Re: [jboss-user] [JBoss Microcontainer Development] - JBoss Reflect Performance Javassist vs Introspection

The flow of these break points is: 1. RegisterModuleCallback.addModule() - bootstrap-classloader:0.0.0 2. RegisterModuleCallback.addModule() - jmx-classloader:0.0.0 3. JBossClDelegatingClassPool() - bootstrap-classloader:0.0.0 4. JBossClDelegatingClassPool() - jmx-classloader:0.0.0 5. Get TypeInfo for AspectManagerJMXRegistrar fails (aop classpool not created yet) 6. RegisterModuleCallback.addModule() - deployers-classloader:0.0.0 7. JBossClDelegatingClassPool() - deployers-classloader:0.0.0 8. Get TypeInfo for AOPAnnotationMetaDataParserDeployer fails (aop classpool not created) 9. Get TypeInfo for AOPDeploymentAopMetaDataDeployer fails (aop classpool not created) 10. Get TypeInfo for BeansDeploymentAopMetaDataDeployer fails (aop classpool not created) 11. RegisterModuleCallback.addModule() - profile-classloader:0.0.0 12. JBossClDelegatingClassPool() profile-classloader:0.0.0 Looking at the sequence of files from bootstrap.xml: * bootstrap/vfs.xml - No classloader * bootstrap/classloader.xml - defines bootstap-classloader:0.0.0 * bootstrap/stdio.xml - defines stdio-classloader:0.0.0 * bootstrap/kernel.xml - defines asynch-classloader:0.0.0 * bootstrap/aop.xml - defines aop-classloader:0.0.0 and the RegisterModuleCallback * bootstrap/jmx.xml - defines jmx-classloader:0.0.0 * bootstrap/deployers.xml - defines deployers-classloader:0.0.0 * bootstrap/profile.xml - defines deployers-classloader:0.0.0 Assuming these get deployed in order (which I will look at next) it seems strange that the RegisterModuleCallback receives bootstrap-, jmx-, deployers- and profile-classloader, but not the aop-, stdio and, asynch-classloaders -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538975#538975] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Another thing to fix or do properly is where and how we define these classpool jars. e.g. in which boostrap sub xml should we define classpool roots; specially with some deployers dependency in the registry -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538972#538972] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

I found later that the jbpm installer is not creating any table in the mysql database even though I am indicating mySQL while installing. I tried after preinstalling mySQL. It never asked me where I have installed mySQl. Later I retried by creating an environment variable MYSQL_HOME (??) I re-istalled with hypersonic database, now the login is going through but ;later jbpmpersistence error is coming. It looks that it is not creating the entire database in the default database( I suppose) also. Please throw more light. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538956#538956] Start a new discussion in jBPM Development PVM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JCA] - Newbie: ORB Notify Channel Source JCA

by Derek Wildstar

Derek Wildstar [http://community.jboss.org/people/starblazer74] created the discussion "Newbie: ORB Notify Channel Source JCA" To view the discussion, visit: http://community.jboss.org/message/538954#538954 -------------------------------------------------------------- Hi Guys, I've created a small JCA Source that is connecting to a Corba Notification channel as push. The connector itself works fine but I guess that I've missed something basilar into ORB setup. With a fresh start of Jboss I can see the banner of Jacorb initialization and my project is receiving messages from channel. However when I stop my project and restart it I can see the Jacorb banner twice (as the ORB object has been initialized twice). Beside implementation details I'm creating ORB instance into endpoint activation using: ORB orb = ORB.init(new String[0], properties) and then calling the following: orb.shutdown(false); orb.destroy() into endpointdeactivation. I'm pretty sure that I've missed something basilar here but at the moment I'm brain dead. Any help or RTFM (but let me know which one) would be appreciated :) Regards Claudio. PS I'm on JBoss 4 and using Jacorb 2.3.1 -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538954#538954] Start a new discussion in JCA at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [JBoss Portal] - IPC sample project ala JSR 286

I've just seen that there was this question... It is less value added than before JSR-286... of course. but still interesting, for the nice explanation of the principles. and for an implementation based on messaging, which have it's advantages in some specific use cases. the main draw back is to make portlets that are not full compliant with the JSR. one use case that can requiere some real messaging is when the message must be received by the portlet. the JSR states it limit like this (page 109) : "Portlet events are not a replacement for reliable messaging (see other JavaEE APIs, like Java Message Service, JMS, for providing reliable messaging). Portlet events are not guaranteed to be delivered and thus the portlet should always work in a meaningful manner even if some or all events are not being delivered." so... it is better if it can be done with the JSR way... but in case of unavoidable need of messaging... this approach is a nice architecture and code base. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538944#538944] Start a new discussion in JBoss Portal at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
