[JBoss AS7 Development] - Extending the Management Model for a Subsystem

by Rob Cernich

Rob Cernich [http://community.jboss.org/people/rcernich] created the discussion "Extending the Management Model for a Subsystem" To view the discussion, visit: http://community.jboss.org/message/614009#614009 -------------------------------------------------------------- Hey all, I'm working on an administrative console for SwitchYard and have a couple of questions regarding the management model. 1. Will the management API (eventually) support node level ACL? (I assume so based on http://community.jboss.org/docs/DOC-16583 http://community.jboss.org/wiki/ManagementAPISecurityAuthorizationRespons...) 2. Is the management API the best architectural choice for exposing operational metrics and operations (e.g. reprocessing messages in a dead-letter queue)? 3. Is the management API the best architectural choice for exposing application specific meta-data (e.g. services defined within a SwitchYard application)? (My concern here relates to transforming SwitchYard application meta-data from its native XML/Java form to a JSON/ModelNode form.) 4. I've read somewhere that the management API plays nicely with JMX. Are there plans to expose the management API through JMX? If so, will additional work be required of the subsystem developer? For more specific details regarding basic SwitchYard requirements, please refer to the following thread: http://community.jboss.org/thread/168791 http://community.jboss.org/thread/168791 Overall, I've been very happy with the functionality provided by the management API and have found it fairly easy to work with. I also like the fact that any functionality I add is easily accessible through the CLI (nice for testing). I just want to make sure I'm heading in the right direction before I get too far along. Thanks in advance, Rob -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/614009#614009] Start a new discussion in JBoss AS7 Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Web Development] - Session Management issue in JBOSS Server

by Nagendra Singh

Nagendra Singh [http://community.jboss.org/people/nagenss] created the discussion "Session Management issue in JBOSS Server" To view the discussion, visit: http://community.jboss.org/message/614102#614102 -------------------------------------------------------------- We are migrating our application from Weblogic Service Pack 6 to JBoss 5.0 server. I have a query related to session management in JBOSS. Scenario on Weblogic Server: If I open 2 instances on the application on 2 tabs of same IE browser, I'm allowed to do that as it generates 2 different session ID for both tabs. Problem Scenario on JBOSS server: I'm able to successfully login to the application for the first time. But when I try to open a new session in the TAB of the same IE browser, it is not allowing me to do that. It is not allowing to generate a new Session ID in JBOSS where as in Weblogic it is allowing me to do so This may be the problem with JBOSS container. In weblogic, the container generates the session ID and sets it in the request object. We fetch the ID using "request.getSession().getId()". (Correct me if my analysis is wrong as I'm new to JBOSS) Thanks in Advance.. :) -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/614102#614102] Start a new discussion in JBoss Web Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss AS7 Development] - JBoss AS7 User Guide

by Brian Stansberry

Brian Stansberry [http://community.jboss.org/people/brian.stansberry] modified the document: "JBoss AS7 User Guide" To view the document, visit: http://community.jboss.org/docs/DOC-16068 -------------------------------------------------------------- h2. Note: This article is an early version of JBoss AS 7 documentation written during the early development phases. Please see the https://docs.jboss.org/author/display/AS7/Documentation JBoss AS 7 Documentation page for the official JBoss AS 7 docs. This is a brief guide intended to help users who wish to experiment with JBoss AS 7 as it undergoes development. Feedback on its content is most appreciated, either via comments on this page, via forum posts in this "JBoss AS7 Development" section of the wiki, or by posts to the https://lists.jboss.org/mailman/listinfo/jboss-development jboss-development mailing list. AS 7 is currently in "Beta" status, so users should not expect all of the capabilities of more stable AS 5 and 6 releases to be present. Users should also be aware that significant changes may be made from one alpha release to another. In addition to this, please reference http://community.jboss.org/en/jbossas/dev/jboss_as7_development?view=tags... all articles tagged #jboss_7_userguide h2. Getting JBoss AS 7 AS 7 is available from the http://www.jboss.org/jbossas/downloads.html jboss.org download page. As in earlier JBoss AS releases, installation consists of unzipping the release distribution. Users are encouraged to check out the AS 7 source and build it themselves. This is quite quick and painless once git is installed on your system, and getting git set up is also quite easy to do. See the http://community.jboss.org/docs/DOC-15596 Hacking On JBoss AS 7 wiki page for more details on working with the AS 7 source. h2. Quick Start Once you have the distribution unzipped, you need to decide whether you want to work in "domain mode" or "standalone mode". See "Domain Mode vs. Standalone Mode" below for more on what those choices mean. If you want to work in domain mode, open a terminal and cd into the distribution's bin directory, and run the "domain" launch script: $ cd bin $ ./domain.sh On Windows: > cd bin > domain.bat This will launch a total of 5 processes on your system: three JBoss AS server instances; a Domain Controller process that acts as a central management point for all servers that belong to the same "domain"; and a lightweight Process Controller process that is responsible for spawning the other 4 processes and monitoring their lifecycle. If you want to work in standalone mode, open a terminal and cd into the distribution's bin directory, and run the "standalone" launch script: $ cd bin $ ./standalone.sh On Windows: > cd bin > standalone.bat This will launch a single process on your system, a standalone JBoss AS server instance. h3. Stopping a running instance of standalone server A running instance of a standalone server can be stopped in either of the following ways: * If you have access to the command prompt console from where you started the server, then pressing Ctrl + C will cleanly shutdown the server. * Alternately, from a new command prompt you can use the following command to trigger a shutdown of the running standalone instance: $ cd bin $ ./jboss-admin.sh --connect command=:shutdown The "--connect" by default connects to localhost at port 9999 and triggers the shutdown. If your server doesn't use the default port or isn't bound to localhost, then you can explicitly specify the host port combination to the --connect as follows: $ ./jboss-admin.sh --connect controller=<IP>:<port> command=:shutdown where <IP> is the IP to which the server is bound and the <port> is the management port. If you have the AS 7 source checked out, there are a number of demos that can be run from the source checkout's demos module. See below for details. h2. Domain Mode vs. Standalone Mode One of the primary new features of AS 7 is the ability to manage multiple AS instances from a single control point. A collection of such servers are referred to as members of a "domain", with a single Domain Controller process acting as the management control point. Domains can span multiple physical (or virtual) machines, with all AS instances on a given host under the control of a Host Controller process. The Host Controllers interact with the Domain Controller to control the lifecycle of the AS instances running on that host and to assist the Domain Controller in managing them. When you launch JBoss AS in "domain mode" (via the domain.sh or domain.bat launch scripts) your intent is to launch a Domain Controller, a Host Controller and usually at least one AS instance. For more on running servers in domain mode, a roughly 20 minute video is available online (divided in two pieces): http://www.youtube.com/watch?v=phV3QiKQf2E http://www.youtube.com/watch?v=phV3QiKQf2E http://www.youtube.com/watch?v=gCeQ2KIO0qc http://www.youtube.com/watch?v=gCeQ2KIO0qc For many use cases, the centralized managment capability available via domain mode is not necessary. For these use cases, the AS can also be run in "standalone mode". In standalone mode each AS instance is an independent process, much like an AS 3, 4, 5, or 6 instance is. Standalone instances can be launched via the standalone.sh or standalone.bat launch scripts. If more than one standalone instance is launched and multi-server management is desired, it is the user's responsibility to coordinate management across the servers. A given server instance cannot be switched between domain mode and standalone mode; i.e. you cannot launch domain.sh, stop the processes, and then launch standalone.sh and expect any relationship between what was running. The configurations are separate. We may in future releases include some tooling to ease the task of translating a given server configuration from domain mode to standalone mode. h4. Deciding Between Domain Mode and Standalone Mode Which use cases are appropriate for domain mode and which are appropriate for standalone mode? Domain mode is all about coordinated multi-server management -- with it JBoss AS provides a central point through which users can manage multiple servers, with rich capabilities to keep those servers' configurations consistent and the ability to roll out configuration changes (including deployments) to the servers in a coordinated fashion. It's important to understand that domain mode and standalone mode are all about how your servers are managed, not what capabilities they have to service end user requests. This distinction is particularly important when it comes to high availability clusters. The current AS 7 beta1 release does not support HA functionality. However, it's important to understand that once HA functionality is added in a later beta, it will be orthogonal to "domain mode" vs. "standalone mode". That is, a group of servers running in standalone mode will be able to be configured to form an HA cluster. The domain and standalone modes determine how the servers are managed, not what capabilities they provide. So, given all that: * A single server installation gains nothing from domain mode, so standalone mode is a better choice. * For multi-server production environments, the choice of domain mode versus standalone mode comes down to whether the user wants to use the centralized management capability domain mode provides. Some enterprises have developed their own sophisticated multi-server management capabilities and are comfortable coordinating changes across a number of independent JBoss AS instances. For these enterprises, a multi-server architecture comprised of individual standalone mode AS instances is a good option. * Standalone mode is better suited for most development scenarios. In particular, there is no "domain mode" for embedding JBoss AS; e.g. in an Arquillian-based testsuite. Any individual server configuration that can be achieved in domain mode can also be achieved in standalone mode, so even if the application being developed will eventually run in production on a domain mode installation, much (probably most) development can be done using standalone mode. * Domain mode can be helpful in some advanced development scenarios; i.e. those involving interaction between multiple AS instances. Developers may find that setting up various servers as members of a domain is an efficient way to launch a multi-server cluster. h2. Contents of the AS 7 Distribution The AS 7 distribution includes the following directories: *bin* -- location of the launch scripts *docs* -- license files, documentation, schemas, examples, etc. The amount of content in this directory will increase as development continues. *modules* -- AS 7 is based on a modular classloading architecture. The various modules used in the server are stored here. Generally speaking, this is not an area that would be modified by end users. *domain* -- only relevant when domain mode is used. Configuration files, deployment content, and writeable areas used by the domain mode processes that run off of this installation. See below for further details. *standalone* -- only relevant when standalone mode is used. Configuration files, deployment content, and writeable areas used by the single standalone server that runs off this installation. See below for further details. h3. Contents of the "domain" Directory Only relevant when domain mode is used. *configuration* -- configuration files for the domain and for the Host Controller and any servers running off of this installation. If we've done our jobs well, these configuration files are the only configuration files end users should need to touch (outside of deployment descriptors in their own application deployments). See below for more on these files. *content* -- an internal working area for the Host Controller that controls this installation. This is where it internally stores deployment content. This directory is not meant to be manipulated by end users. *log* -- location where the Process Controller and Host Controller write their log files. *servers* -- writeable area used by each AS instance. Each AS instance will have its own subdirectory, created when the server is first started. In each server's subdirectory there will be the following subdirectories: data -- information written by the server that needs to survive a restart of the server log -- the server's log files tmp -- location for temporary files written by the server *system-content* -- an internal working area. Storage for non-end-user deployments; i.e. deployments that the subsystems that comprise a running AS themselves deploy into the runtime as part of the service they provide. (Not used in Beta1, removed for Beta2.) h3. Contents of the "standalone" Directory Only relevant when standalone mode is used. *configuration* -- configuration files for the standalone server that runs off of this installation. If we've done our jobs well, these configuration files are the only configuration files end users should need to touch (outside of deployment descriptors in their own application deployments). See below for more on these files. *data* -- information written by the server that needs to survive a restart of the server *deployments* -- an area where end user deployment content can be placed if automatic detection and deployment of that content into the server's runtime is desired. The server's management API exposes other means for installing deployment content, and use of that API in preference to the deployments directory is preferred. We realize however, that at this early stage in AS 7's development the tooling around the deployment API is in its infancy, so many users will utilize the deployments directory to deploy content. Note that "domain mode" does not support deploying content based on scanning a filesystem. *log* -- the server's log files *tmp* -- location for temporary files written by the server *system-content* -- an internal working area. Storage for non-end-user deployments; i.e. deployments that the subsystems that comprise a running AS themselves deploy into the runtime as part of the service they provide. (Not used in Beta1, removed for Beta2.) h2. "Domain Mode" Configuration Files Located in the *domain/configuration* directory. *domain.xml* -- primary configuration file for the domain. Among other things, includes the configuration of the various "profiles" that AS instances can be configured to run. A profile configuration includes the detailed configuration of the various subsystems that comprise that profile (e.g. an embedded JBoss Web instance is a subsystem; a JBoss TS transaction manager is a subsystem, etc). Includes the definition of groups of sockets that those subsystems may open. And includes definition of "server groups", to which a profile, a group of socket definitions and zero or more deployments are mapped. Each individual server will be mapped (in host.xml, see below) to a server group; the configuration of that server group largely defines the configuration of the individual server. A domain.xml file must be located in the domain/configuration directory of an installation that's meant to run the Domain Controller. It does not need to be present in installations that are not meant to run a Domain Controller; i.e. those whose Host Controller is configured to contact a remote Domain Controller. The presence of a domain.xml file on such a server does no harm; it will be ignored. Users are encouraged to have a look at the https://github.com/jbossas/jboss-as/blob/master/controller/src/main/resou... AS 7 configuration schema, starting with the <domain> element, to learn more about configuration of a Domain Controller. *host.xml* -- configuration file for the Host Controller that runs off of this particular installation. Each installation must have a host.xml file. Contains configuration information that is specific to the particular installation. Primarily: * the listing of the names of the actual AS server instances that are meant to run off of this installation, along with the server group they belong to. * configuration of how the Host Controller is to contact the Domain Controller to register itself and access the domain configuration. This may either be configuration of how to find and contact a remote Domain Controller, or a configuration telling the Host Controller to itself act as the Domain Controller. * configuration of items that are specific to the local physical installation. For example, named interface definitions declared in domain.xml can be mapped to an actual machine-specific IP address in host.xml. Abstract path names in domain.xml can be mapped to actual filesystem paths in host.xml. Users are encouraged to have a look at the https://github.com/jbossas/jboss-as/blob/master/controller/src/main/resou... AS 7 configuration schema, starting with the <host> element, to learn more about configuration of a Host Controller. *logging.properties* -- Contains the logging configuration for the Host Controller and Process Controller that run off of this installation. Also defines the initial bootstrap logging configuration for each individual AS instance. This boostrap logging configuration is replaced with the logging configuration specified in the domain.xml file once the server boot has reached the point where that configuration is available. h2. "Standalone Mode" Configuration Files Located in the *standalone/configuration* directory. *standalone.xml* -- primary configuration file for the AS instance. Among other things, includes the configuration of the "profile" that the AS instance is configured to run. A profile configuration includes the detailed configuration of the various subsystems that comprise that profile (e.g. an embedded JBoss Web instance is a subsystem; a JBoss TS transaction manager is a subsystem, etc). Also includes the definition of the sockets that those subsystems may open. Users are encouraged to have a look at the https://github.com/jbossas/jboss-as/blob/master/controller/src/main/resou... AS 7 configuration schema, starting with the <server> element, to learn more about configuration of a standalone AS instance. *logging.properties* -- Contains the initial bootstrap logging configuration for the AS instance. This boostrap logging configuration is replaced with the logging configuration specified in the standalone.xml file once the server boot has reached the point where that configuration is available. h2. General Configuration Concepts In both Domain Mode and Standalone Mode a number of common configuration concepts apply: h4. Extensions An extension is a module that extends the core capabilities of the server. The AS core is very simple and lightweight; most of the capabilities people associate with an application server are provided via extensions. An extension is packaged as a module in the modules folder. The user indicates that they want a particular extension to be available by including an <extension/> element naming its module in the domain.xml or standalone.xml file. <extensions> ... <extension module="org.jboss.as.transactions"/> <extension module="org.jboss.as.web" /> <extension module="org.jboss.as.webservices" /> <extension module="org.jboss.as.weld" /> </extensions> h4. Paths A logical name for a filesystem path. The domain.xml, host.xml and standalone.xml configurations all include a section where paths can be declared. Other sections of the configuration can then reference those paths by their logical name, rather than having to include the full details of the path (which may vary on different machines). For example, the logging subsystem configuration includes a reference to the "jboss.server.log.dir" path that points to the server's "log" directory. <file relative-to="jboss.server.log.dir" path="server.log"/> The AS automatically provides a number of standard paths without any need for the user to configure them in a configuration file: * jboss.home - the root directory of the JBoss AS distribution * user.home - user's home directory * user.dir - user's current working directory * java.home - java installation directory * jboss.server.base.dir - root directory for an individual server instance * jboss.server.data.dir - directory the server will use for persistent data file storage * jboss.server.log.dir - directory the server will use for log file storage * jboss.server.tmp.dir - directory the server will use for temporary file storage * jboss.domain.servers.dir - directory under which a host controller will create the working area for individual server instances (domain mode only) Users can add their own paths or override all except the first 5 of the above by adding a <path/> element to their configuration file. <path name="example" path="example" relative-to="jboss.server.data.dir"/> See the XSD for details. A <path/> element in a domain.xml need not include anything more than the name attribute; i.e. it need not include any information indicating what the actual filesystem path is: <path name="x"/> Such a configuration simply says, "There is a path named 'x' that other parts of the domain.xml configuration can reference. The actual filesystem location pointed to by 'x' is host-specific and will be specified in each machine's host.xml file." If this approach is used, there must be a path element in each machine's host.xml that specifies what the actual filesystem path is: <path name="x" path="/var/x" /> h4. Interfaces h4. A logical name for a network interface/IP address/host name to which sockets can be bound. The domain.xml, host.xml and standalone.xml configurations all include a section where interfaces can be declared. Other sections of the configuration can then reference those interfaces by their logical name, rather than having to include the full details of the interface (which may vary on different machines). An interface configuration includes the logical name of the interface as well as information specifying the criteria to use for resolving the actual physical address to use. The criteria is one of two types: either a single element indicating that the interface should be bound to a wildcard address, or a set of one or more characteristics that an interface or address must have in order to be a valid match. <interface name="global">  <any-address/> </interface> <interface name="external"> <nic name="eth0"/> </interface> <interface name="default">  <subnet-match value="192.168.0.0/16"/> <up/> <multicast/> <not> <point-to-point/> </not> </interface> <interface name="loopback"> <inet-address value="127.0.0.1"/> </interface> See the XSD for full details on the various criteria options. An <interface/> element in a domain.xml need not include anything more than the name attribute; i.e. it need not include any information indicating what the actual IP address associated with the name is: <interface name="internal"/> Such a configuration simply says, "There is an interface named 'internal' that other parts of the domain.xml configuration can reference. The actual IP address pointed to by 'internal' is host-specific and will be specified in each machine's host.xml file." If this approach is used, there must be an interface element in each machine's host.xml that specifies the criteria for determining the IP address: <interface name="internal"> <nic name="eth1"/> </interface> h4. Socket Bindings and Socket Binding Groups A socket binding is a named configuration for a socket. The domain.xml and standalone.xml configurations both include a section where named socket configurations can be declared. Other sections of the configuration can then reference those sockets by their logical name, rather than having to include the full details of the socket configuration (which may vary on different machines). A socket binding includes the following information: * name -- logical name of the socket configuration that should be used elsewhere in the configuration * port -- base port to which a socket based on this configuration should be bound. (Note that servers can be configured to override this base value by applying an increment or decrement to all port values. See below for more details.) * interface (optional) -- logical name (see "Interfaces" above) of the interface to which a socket based on this configuration should be bound * multicast-address (optional) -- if the socket will be used for multicast, the multicast address to use * multicast-port (optional) -- if the socket will be used for multicast, the multicast port to use * fixed-port (optional, defaults to false) -- if true, declares that the value of port should always be used for the socket and should not be overridden Socket binding configurations are organized inside a <socket-binding-group/> element. That element also includes a default-interface attribute; that interface will be used for any bindings that do not specify their interface attribute. h4. System Properties System property values can be set in a number of places in domain.xml, host.xml and standalone.xml. The values in standalone.xml are set as part of the server boot process. Values in domain.xml and host.xml are applied to servers when they are launched. h4. Profiles and Subsystems The most significant part of the configuration in domain.xml and standalone.xml is the configuration of one (in standalone.xml) or more (in domain.xml) "profiles". A profile is a named set of subsystem configurations. A subsystem is an added set of capabilities added to the core server by an extension (see "Extensions" above). A subsystem provides servlet handling capabilities; a subsystem provides an EJB container; a subsystem provides JTA, etc. A profile is a named list of subsystems, along with the details of each subsystem's configuration. A profile with a large number of subsystems results in a server with a large set of capabilities. A profile with a small, focused set of subsystems will have fewer capabilities but a smaller footprint. The content of an individual profile configuration looks largely the same in domain.xml and standalone.xml. The only difference is standalone.xml is only allowed to have a single profile element (the profile the server will run), while domain.xml can have many profiles, each of which can be mapped to one or more groups of servers. The profile element in domain.xml also supports an <includes profile="another_profile"/> tag which allows configuration reuse whereby several more complex profiles can include the contents of simpler profiles. The contents of individual subsystem configurations look exactly the same between domain.xml and standalone.xml. h2. Standalone Mode Configuration Concepts In addition to the general configuration concepts described above, the following concepts are specific to an AS instance running in standalone mode. h4. Server Name The root <server/> element in standalone.xml include a name attribute. If set, the value becomes the name of the server. If not set If not set, defaults to the runtime value of java.net.InetAddress.getLocalHost().getHostName(). Users are encouraged to use distinct names for all servers in the operational environment. The server name is made available to all services running in the server. h4. Paths and Interfaces As mentioned above, domain.xml supports not fully describing a path (by providing the actual filesystem path) or an interface (by providing criteria to determine the IP address to use). This is not supported in standalone.xml. h4. Socket Binding and Avoiding Port Conflicts In standalone.xml, only a single <socket-binding-group/> element is allowed. In standalone.xml, the <socket-binding-group/> element can also include a port-offset attribute. The value of this attribute will be added to the port attribute value for any binding to derive the actual port to use for the socket. Setting the port-offset to a value other than zero allows multiple AS instances with the same socket binding and interface configurations to run on the same machine without having port conflicts. In domain.xml the <socket-binding-group/> element does not include a port-offset attribute; see "Domain Mode Configuration Concepts" below for more on how an equivalent configuration is done. h4. Profiles As noted above, only a single profile element is allowed in standalone.xml. h4. Deployments The standalone.xml file includes a section listing the deployment content available for use on the server. Deployment content is made available for use either by uploading it using the AS's management APIs, or by configuring a deployment scanner service and placing the content in the folder scanned by that service (i.e. the deployments/ folder.) Each deployment element includes the following information: * name -- Unique identifier of the deployment. Must be unique across all deployments. * runtime-name -- name by which the deployment should be known within the runtime. This would be equivalent to the file name of a deployment file, and would form the basis for such things as default Java Enterprise Edition application and module names. This would typically be the same as name, but in some cases users may wish to have two deployments with the same runtime-name may (e.g. two versions of "foo.war") both available in the deployment content repository, in which case the deployments would need to have distinct name values but would have the same runtime-name * hash -- a hash of the deployment content, created by the server when the content was uploaded. The server uses the hash internally to find content in the repository. * start -- a boolean flag indicating whether the content is actually deployed into the runtime (and should be automatically deployed when the server starts.) h2. Domain Mode Configuration Concepts In addition to the general configuration concepts described above, the following concepts are specific to configuring a set of JBoss AS instances in domain mode. h4. Domain.xml vs Host.xml Domain configuration is divided into two portions: a set of configuration elements that is consistent on all hosts across the domain (stored in the domain.xml file on the host that is acting as the Domain Controller), and a set of configuration elements that differs on each host (stored in a host.xml on each host). Most configuration should come from the domain.xml; the host.xml is meant to be limited to details that need to vary from one host to another (e.g. IP addresses, filesystem paths, and, most significantly the names of the servers that should run on each host. Each host's Host Controller is responsible for launching the servers configured in its host.xml file. To do this the Host Controller gets a copy of the domain-wide configuration from the Domain Controller, extracts the portion of the domain-wide configuration that is relevant to the server (e.g. the details of the profile the server is configured to run), applies host-specific information (e.g. the IP addresses to use for named interfaces), and creates a server-specific configuration. The Host Controller then launches the server process and provides it its configuration. If that server-specific configuration were represented in XML form, it would look the same as a standalone.xml file -- the Host Controller essentially synthesizes a standalone.xml from the relevant domain.xml and host.xml content. h3. Domain.xml Configuration Concepts h4. Profiles As noted above, the domain.xml file can contain multiple profiles. Different servers in the domain can run different profiles. h4. Paths and Interfaces As discussed above, path and interface elements in domain.xml can legally include nothing more than the name of the path or interface, in which case each host.xml is responsible for specifying the details of the path or interface. h4. Deployments The Domain Controller maintains a repository of deployment content that is available for use in the servers in the domain. The domain.xml file includes a section listing the deployment content available for use in the domain. Deployment content is made available for use by uploading it using the AS's management APIs. Each deployment element includes the following information: * name -- Unique identifier of the deployment. Must be unique across all deployments in the domain. * runtime-name -- name by which the deployment should be known within the runtime. This would be equivalent to the file name of a deployment file, and would form the basis for such things as default Java Enterprise Edition application and module names. This would typically be the same as name, but in some cases users may wish to have two deployments with the same runtime-name may (e.g. two versions of "foo.war") both available in the deployment content repository, in which case the deployments would need to have distinct name values but would have the same runtime-name * hash -- a hash of the deployment content, created by the server when the content was uploaded. The server uses the hash internally to find content in the repository. Note that the fact that a deployment is listed in the domain-level deployments listing does not mean it will actually be deployed on any servers. It simply means its content is known to the domain and available for use. Deployments are only deployed on servers when they are mapped to server groups (see below). h4. Server Groups Besides the general configuration concepts described in the "General Configuration Concepts" section above, the most important element in the domain.xml is the definition of Server Groups. Each AS instance is a member of a server group. (Even if the group only has a single server, the server is still a member of a group.) It is the responsibility of the domain management system to ensure that all servers in a server group have a consistent configuration. They should all be configured with the same profile and they should have the same deployment content deployed. The domain can have multiple server groups. An example server group definition is as follows: <server-group name="main-server-group" profile="default"> <socket-binding-group ref="standard-sockets"/> <deployments> <deployment name="foo.war_v1" runtime-name="foo.war" hash="ABCDEFG1234567890ABC"/> <deployment name="bar.ear" runtime-name="bar.ear" hash="1234567890ABCDEFG123"/> </deployments> </server-group> A server-group configuration includes the following required attributes: * name -- the name of the server group * profile -- the name of the profile the servers in the group should run In addition, the following optional elements are available: * socket-binding-group -- specifies the name of the default socket binding group to use on servers in the group. Can be overridden on a per-server basis in host.xml. If not provided in the server-group element, it must be provided for each server in host,xml. * deployments -- the deployment content that should be deployed on the servers in the group. * system-properties -- system properties that should be set on all servers in the group * jvm -- default jvm settings for all servers in the group. The Host Controller will merge these settings with any provided in host.xml to derive the settings to use to launch the server's JVM. See the "JVMs" section in "Host.xml Configuration Concepts" below. h3. Host.xml Configuration Concepts h4. Paths and Interfaces Any paths or interfaces declared in domain.xml but not fully specified there need to be fully specified in host.xml. Since filesystem paths and IP addresses often vary from host to host, these details are often provided in eac host's host.xml. h4. System Properties System property values can be declared in a top level element in host.xml. Properties declared here will be set on all servers launched on the host. h4. JVMs The host.xml file can include one or more named JVM configurations. The configurations will include such details as the location of the JVM binary, heap sizes, environment variables, etc. The individual server configurations can refer to one of these JVM configurations by name and the Host Controller will use the named configuration to launch the server. Note that JVM configuration details can also come from the server-group element in domain.xml and from the individual server element (see below.) If configured in more than one place, the elements will be merged, with server element values taking priority over server-group values, which in turn take priority over the host-level jvm configuration. h4. Management Interfaces The configuration of the connectors the Host Controller exposes to support remote management. TODO details h4. Domain Controller Configuration of how the Host Controller should find and communicate with the Domain Controller: <domain-controller>  <remote host="192.168.100.1" port="9999"/> </domain-controller> TODO details If this host should act as Domain Controller, this is declared as follows: <domain-controller> <local/> </domain-controller> h4. h4. Servers The most significant configuration item in host.xml is the listing of the servers that should be launched on the host. Each server has its own element: <servers> <server name="server-one" group="main-server-group">  <jvm name="default" /> </server> <server name="server-two" group="main-server-group" start="true">  <socket-binding-group ref="standard-sockets" port-offset="150"/> <jvm name="default"> <heap size="64m" max-size="256m"/> </jvm> </server> <server name="server-three" group="other-server-group" start="false">  <socket-binding-group ref="standard-sockets" port-offset="250"/> </server> </servers> Each server element includes the following required attributes: * name -- the name of the server. Must be unique across the host. * group -- the name of the server-group the server is a member of * start -- (defaults to true) whether the server should be automatically started when the Host Controller starts In addition, the server element includes the following optional elements: * socket-binding-group -- the name of the socket binding group to use. Besides the socket binding group name, a port-offset can also be configured. The value of this attribute will be added to the port attribute value for any binding to derive the actual port to use for the socket. Setting the port-offset to a value other than zero allows multiple AS instances with the same socket binding and interface configurations to run on the same machine without having port conflicts. * paths -- allows specification of paths at the individual server level. Configurations at this level will override any configurations with the same name at the domain or host level. * interface-specs -- allows specification of interfaces at the individual server level. Configurations at this level will override any configurations with the same name at the domain or host level. * system-properties -- system properties values specific to this server * jvm -- jvm configurations for this server h2. Available Subsystems AS 7 is under active development. Not all capabilities present in more mature releases of the AS 5 and 6 series are available in AS 7 yet. Following is a brief listing of the subsystems available in the various AS 7 releases. Items listed below may not be entirely feature complete. h4. 7.0.0.Beta1 * logging -- configuration of logging appenders, categories, etc * threads -- thread pool management * sockets -- socket binding management * naming -- local JNDI. Note that direct remote access to JNDI is not supported in Alpha1 (see the client.jms demo for an example of a clever hack to get remote access to JNDI via an MBeanServerConnection) * transactions -- JTA * jmx -- MBeanServer with remote access capability * web -- basic servlet and JSP support * ee - common EE facilities (injection etc) * ejb3 - EJB3 component implementaton * jax-rs - RestEasy integration * messaging -- HornetQ server * JMS -- JMS queues, topics and connection factories * JCA connectors * Datasources * JCA resource adapter deployments * osgi -- OSGI bundle deployment * remoting -- JBoss Remoting 3 connectors * managed beans -- EE 6 managed bean deployments * SAR deployments -- both legacy mbean deployments and those based on the JDK 6 ServiceLoader concept. Note that not all legacy sar capabilities are supported * Filesystem based hot deployment scanning (standalone mode only) -- note that exploded deployments are not currently supported h2. Demos in the Source Checkout The source checkout includes a "demos" module that includes a number of demos that can be run from maven. Building the module from the /demos directory will output a usage note that explains how to run the demos: usage: [echo] To run an example: [echo] 1) In a separate console window,start either a standalone JBoss AS instance or a JBoss AS domain [echo] 2) Run mvn package -Dexample=<example.name> where "exammple.name is the name of the example [echo] [echo] Valid example names to run against a standalone JBoss AS instance are [echo] sar - deploys mbeans packaged in a sar [echo] managedbean - deploys a managed bean [echo] serviceloader - deploys a serviceloader style service [echo] messaging - deploys HornetQ native sender and receiver [echo] jms - deploys HornetQ JMS sender and receiver [echo] jms.client - Uses HornetQ JMS API from the client [echo] rar - deploys a resource adapter [echo] ds - deploys a test bean for data sources [echo] war - deploys a simple servlet and connects to it [echo] client.messaging - creates a HornetQ core queue using the management API [echo] client.jms - creates a JMS queue using the management API [echo] web.connector - creates and removes a jboss web connector [echo] [echo] Valid example names to run against a JBoss AS domain are [echo] domain.configs - reads the domain config and any available host controller configs [echo] domain.ds - deploys deploys a test bean for data sources [echo] domain.messaging - deploys HornetQ native sender and receiver [echo] domain.rar - deploys deploys a resource adapter [echo] domain.servers - shows domain, host controller and server configs, starts/stops servers The primary point of the demos is to look at the source code and see how they use the AS's management API to deploy content and/or alter the configuration of the running server(s). To see how an example works, look at the relevant demos/src/main/java/org/jboss/as/demos/<example.name>/runner.ExampleRunner.java file. -------------------------------------------------------------- Comment by going to Community [http://community.jboss.org/docs/DOC-16068] Create a new document in JBoss AS7 Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=102&co...]

[JBoss ESB Development] - Re: httprouter issues with GET/POST WADL Services and Web Routing

You have to use a different style of URL/Resource styling. Something like: http://localhost:8080/esbRestProxy/http/esb-proxy/simple/customers/1 http://localhost:8080/esbRestProxy/http/esb-proxy/simple/customers?id=1 @GET @Produces("application/xml") *public* StreamingOutput getCustomer(@QueryParam("id") *int* id) { .... } It kinda sucks, it is a limitation of SOA-P. As far as I know, you can not accomplish this with the current version 5.0.2. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/614008#614008] Start a new discussion in JBoss ESB Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-dev-forums] [JBoss AS7 Development] - Data Source Configuration in AS 7

by Gerry Matte

Gerry Matte [http://community.jboss.org/people/gerry.matte] commented on the document "Data Source Configuration in AS 7" To view all comments on this document, visit: http://community.jboss.org/docs/DOC-16657#comment-6977 -------------------------------------------------- Good suggestion to create an XA datsource using the web interface (admin console). After I created an XA datasource using the admin cvonsole, the differences were obvious. An XA datasource (using an XA driver such as used in this example) should probably use the xa-datasource tag rather than the datasource tag - see the second code line in "Defining the Datasource itself". That choice of tag seems to govern which admin console tab displays the completed datasource. Configuring an XA datasource using the standard datasource tag seems to work ok - my test servlet was able to lookup the datasource, get a connection, and execute an sql statement with no exceptions thrown. If you choose to use xa-datasource, the datasource properties are defined using the xa-datasource-property tag. --------------------------------------------------

[JBoss AS7 Development] - Adding an Operation Handler for an AS 7 Subsystem

by Brian Stansberry

Brian Stansberry [http://community.jboss.org/people/brian.stansberry] modified the document: "Adding an Operation Handler for an AS 7 Subsystem" To view the document, visit: http://community.jboss.org/docs/DOC-16655 -------------------------------------------------------------- h3. WARNING: This article is out of date as of AS 7.0.0.CR1 and will be rewritten. This article is a quick description of the steps needed to add a new handler to an AS7 subsystem for handling a management operation. This is as of the AS 7.0.0.Beta1 release. Developers are encouraged to look at the latest code as a better source for understanding the process. Looking at the handlers in the org.jboss.as.web package in the AS 7 source tree's web/ module is a good approach. h3. Handling the Operation 1) The handler must implement the org.jboss.as.controller.OperationHandler interface or one of its subinterfaces. /** * Execute the operation, passing the result to {@code resultHandler}. The submodel is not available * unless one of the subtypes of this interface is implemented. This method <b>must</b> invoke one of * the completion methods on {@code resultHandler} regardless of the outcome of the operation. * * * @param context the context for this operation * @param operation the operation being executed * @param resultHandler the result handler to invoke when the operation is complete * @return a handle which may be used to asynchronously cancel this operation or retrieve the compensating model operation * @throws OperationFailedException If the operation fails to execute correctly */ OperationResult execute(OperationContext context, ModelNode operation, ResultHandler resultHandler) throws OperationFailedException; 2) Handlers that need to read or write the persistent management model (i.e. ones that don't solely deal with their subsystem's runtime services) must implement one of the following marker interfaces: * ModelQueryOperationHandler -- for handlers that only read the persistent management model * ModelAddOperationHandler -- for handlers that add a new +addressable resource+ to the model. (Inserting an attribute value for an existing resource is different.) Typically all handlers that implement this interface would be for an operation named "add". * ModelRemoveOperationHandler -- for handlers that remove a +addressable resource+ from the model+.+ (Removing an attribute value for an existing resource to is different.) Typically all handlers that implement this interface would be for an operation named "remove". * ModelUpdateOperationHandler -- for handlers that update existing resources in the persistent management model. (Note: these marker interfaces may be replaced with a diferent mechanism for providing this information before AS 7.0.0.CR1) 3) Handlers are encouraged to perform some validation on the parameters contained in the passed in operation ModelNode. See the org.jboss.as.controller.operations.validation package for some general purpose helpers. If any parameter is invalid, the handler should throw OperationFailedException. OFE is the preferred exception for pretty much any failure condition. 4) If the handler needs to read or write the persistent management model, they can get a reference to the portion of the model indicated by the operation's address by calling context.getSubModel() on the passed in OperationContext. 5) If the operation doesn't throw an exception but the effect of the operation can be reversed via another operation, the operation should create a ModelNode that represents that "compensating operation" (E.g. an operation that sets an attribute to a new value would create a ModelNode that represents an operation to set the attribute back to the old value.) Pass this compensating operation out by calling return new BasicOperationResult(compensatingOperation) If there is no valid compensating operation (e.g. for a read-only operation) then return new BasicOperationResult(); 6) Handlers that seek to alter the runtime state are encouraged to do so asynchronously (i.e. after the call to OperationHandler.execute() returns . This is done by calling context.getRuntimeContext() on the passed in OperationContext. * If that method returns null, the controller that called the handler has determined that it's currently inappropriate to execute runtime operations. The handler should not attempt to alter runtime state. * Otherwise, the handler should create an object that implements the org.jboss.as.controller.RuntimeTask interface. This typical idiom is to create an anonymous inner class inside the OperationHandler.execute() method. This RuntimeTask should be passed to the calling context via a call to context.getRuntimeContext().setRuntimeTask(theTask) The ModelController that called OperationHandler.execute() will ensure that either the runtime task is run or the changes made by the handler to the model are discarded. The RuntimeTask *must* ensure that one (and only one) of the following methods is invoked on the passed in RuntimeHandler: * handleResultComplete() -- if the runtime task is able to perform its changes successfully * handleResultFailed(ModelNode failureDescription) -- if some problem occurs. The failureDescription should describe the problem. The RuntimeTask need not invoke the ResultHandler directly. A common idiom is to install or remove an MSC Service in the RuntimeTask and to add a listener that invokes the RuntimeHandler when the service is started, stopped or fails. See ResultHandler.ServiceStartListener and ResultHandler.ServiceRemoveListener for ready-to-use listener implementations. When the RuntimeTask executes, it is provided a RuntimeTaskContext from which it can get access to an MSC ServiceTarget and ServiceRegistry. 7) All handlers *must* do one (and only one) of the following in the execute method: * Throw an exception (preferably OperationFailedException) * On the passed in ResultHandler, invoke resultHandler.handleResultComplete() * Register a RuntimeTask as described in 6) above. 8) Handlers must be thread safe. The handler can assume that any object passed in is thread safe (including the model made available via OperationContext.getSubModel()). h3. Describing the Operation All operations except "write-attribute" handlers (see below) must have a description that management API callers can access. The description is registered with the core management system along with the OperationHandler (see "Registering the Operation" below). The description must come from an implementation of the org.jboss.as.controller.descriptions.DescriptionProvider interface. /** * Gets the descriptive information (human-friendly description, list of attributes, * list of children) describing a single model node or operation. * <p> * The implementation must assume that the caller intends to modify the * returned {@code ModelNode} so it should not hand out a reference to any internal data structures. * * @param locale the locale to use to generate any localized text used in the description. * May be {@code null}, in which case {@link Locale#getDefault()} should be used * * @return {@link ModelNode} describing the model node's structure */ ModelNode getModelDescription(Locale locale); It is recommended that the handler implement the org.jboss.as.controller.descriptions.DescriptionProvider interface. When the OperationHandler implementation is registered, a DescriptionProvider impl must be registered with it, and having the same class implement both interfaces works well. See http://community.jboss.org/docs/DOC-16317 http://community.jboss.org/docs/DOC-16317 for details on what the DescriptionProvider should return. All free-form text output from a DescriptionProvider must be externalized into a ResourceBundle. It is strongly encouraged that DescriptionProvider implementations have minimal code, and instead invoke a static method in a separate utility class. A typical idiom is to call that utility class XYZSubsystemDescriptions. The goal here is to improve boot time performance by not loading all the often-verbose code needed to generate description when the DescriptionProvider implemenation is loaded. Instead the code is loaded when the DescriptionProvider is invoked, which in many cases (e.g. embedded testing) will never occur. h3. Handlers for the "write-attribute" Operation The system includes a special operation called "write-attribute". This operation exists for every resource and takes two single parameters: * name -- the name of the attribute that is being written * value -- the new value of the attribute This operation is logically equivalent to a JMX setAttribute call. Calls to "write-attribute" will only be accepted for attributes that have had an OperationHandler registered (see below). The handler must know how to access the "name" and "value" parameters. There is no need to write a DescriptionProvider to associate with the OperationHandler for a "write-attribute" operation. h3. Registering the Operation Your OperationHandler will only be invoked if the core management system knows about it. This is done by registering the handler as part of the subsystem's implementation of the org.jboss.as.controller.Extension interface, in the implementation of the Extension.initialize(ExtensionContext context) method. Assume that the resource to which your operation applies had been registered as follows: public void initialize(ExtensionContext context) { final SubsystemRegistration subsystem = context.registerSubsystem(SUBSYSTEM_NAME); final ModelNodeRegistration resource = subsystem.registerSubsystemModel(getTheRootResourceDescription()); If your OperationHandler is a handler for the "write-attribute" operation, e.g. for the "foo" attribute, it would generally be registered as follows: resource.registerReadWriteAttribute("foo", null, handler, AttributeAccess.Storage.CONFIGURATION); The second parameter is usually null. It could be an OperationHandler that is able to handle the "read-attribute" operation for the "foo" attribute. If null, a default handler is used that reads the current attribute value from the persistent configuration model. The final parameter is either AttributeAccess.Storage.CONFIGURATION or AttributeAccess.Storage.RUNTIME. This indicates where the attribute value is stored. CONFIGURATION means it is stored in the persistent configuration; RUNTIME means it is stored in runtime memory only and the value will be lost on server restart. For all other operations, the OperationHandler is registered as follows: resource.registerOperationHandler("my-operation-name", handler, descriptionProvider); where "my-operation-name" is the name of the operation the end user would invoke to trigger your handler. A common idiom is to have the same class implement OperationHandler and DescriptionProvider, to make that class a singleton, and to declare the operation name as a constant on the handler class: resource.registerOperationHandler(MyHandler.OPERATION_NAME, MyHandler.INSTANCE, MyHandler.INSTANCE); There are some overloaded variants of ModelNodeRegistration.registerOperationHandler() that may be useful in some unusual situations.
