[JBoss Messaging Development] - Cluster Topic with console applications as subscribers

by mariqn nenchev

mariqn nenchev [http://community.jboss.org/people/mnenchev] created the discussion "Cluster Topic with console applications as subscribers" To view the discussion, visit: http://community.jboss.org/message/536919#536919 -------------------------------------------------------------- Hi, I have two jboss instances running in cluster. I deployed clustered topic, which i want to be used by external java se console apps. My ear app is sending messages to the topic and all console apps must receive them, no matter from which node they are sent. I tested this scenario with two jboss instances on different machines and two console apps on the same machines. For some reason only the local subscriber receives the message. I.e.: node1:send message ->console app 1 receives, console app 2 does not. node2:send message ->console app 2 receives, console app 1 does not. Any ideas? The topic is marked as true. And i both the console apps are subscribed successfully. Jboss also successfully forms a cluster. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536919#536919] Start a new discussion in JBoss Messaging Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss AOP] - Problem to get custom interceptor stack up and running.

by Jonas Heineson

Jonas Heineson [http://community.jboss.org/people/heineson] created the discussion "Problem to get custom interceptor stack up and running." To view the discussion, visit: http://community.jboss.org/message/536906#536906 -------------------------------------------------------------- Hello, I have a problem getting an interceptor stack up and running on my JBoss (4.2.3.GA). The jboss starts fine, without any error messages, but when I connect a client to the server I get a NullPointerException suggesting that my Interceptor is not loaded (since it is the first one on the stack): ... Caused by: java.lang.NullPointerException at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:101) at org.jboss.ejb3.stateless.StatelessClusteredProxy.invoke(StatelessClusteredProxy.java:112) ... The stack in question is a modified version of the default ClusteredStatelessSessionClientInterceptors stack defined in ejb3-interceptors-aop.xml: jboss-aop.xml: <interceptor scope="PER_VM"/> <stack name="MtClusteredStatelessSessionClientInterceptors">  <interceptor-ref name="com.computas.mt.jboss.clustering.FixedServerInterceptor"/> <interceptor-ref name="org.jboss.aspects.security.SecurityClientInterceptor"/> <interceptor-ref name="org.jboss.aspects.tx.ClientTxPropagationInterceptor"/> <interceptor-ref name="org.jboss.aspects.remoting.ClusterChooserInterceptor"/> <interceptor-ref name="org.jboss.aspects.remoting.InvokeRemoteInterceptor"/> </stack> Annotations of SLSB class: @Stateless(name="EJBSingletonInvoker") @Clustered(loadBalancePolicy = FixedServerBalancer.class) @RemoteBinding(interceptorStack = "MtClusteredStatelessSessionClientInterceptors") public class MtEJBSingletonInvokerBean { ...} Interceptor: public class FixedServerInterceptor extends ClusteredIsLocalInterceptor { @Override public Object invoke(Invocation invocation) throws Throwable { // doing some extra stuff return super.invoke(invocation); } The jboss-aop.xml and the custom interceptor are both located in a module called mt-aop-<version>.aop which is in turn placed in an .ear together with the other modules of the application. Have also turned on instrumentation in the jboss-aop-jdk50.deployer/META-INF/jboss-service.xml What am I missing / doing wrong here?

Re: [jboss-user] [JBoss Microcontainer] - How can I disable bean lifecycles per entire descriptor?

To view the discussion, visit: http://community.jboss.org/message/536897#536897 -------------------------------------------------------------- Ales, Thanks for the providing the project link as ref. I think I understand what you're saying about using the BeanMetaDataFactory for grouping of beans method. I tried look into the jboss-threads-metadata, but I didn't see a sample of descriptor using the ThreadsMetaData yet. So I am still not clear as how would you apply the ignore rule to the entire group of beans. Would I need to programmatically disable this inside the BeanMetaDataFactory instance's implementation (like in ThreadsMetatData.java), or simply adding the <create method="create" ignore="true"> under the <my-group xmlns="urn:foo:bar:1.0"> in descriptor XML file would work? Thanks, /Z -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536897#536897] Start a new discussion in JBoss Microcontainer at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [JBoss Microcontainer] - Is it possible to add classloader root with wildcard pattern?

To view the discussion, visit: http://community.jboss.org/message/536890#536890 -------------------------------------------------------------- > When writing deployment <classloader>, is it possible to specify a wildcard parttern like "<lib>/myapp/lib/*.jar</lib>" instead of single entry at time with <root>? Again, not out of the box, but it's only two classes that you need to extend. New module class (X), so you have your own determineVFSRoots() impl -- which understands wildcard: * override VFSClassLoaderPolicyModule And new XML mapped VFSClassLoaderFactory to override the getModuleClass -- returning X. * custom <classloader> element -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536890#536890] Start a new discussion in JBoss Microcontainer at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Is it possible to have remote access to jBPM without hibernate? For example: We have a system x and we want to start a workflow from jBPM by using the services (RepositoryService, TaskService, .....). Is this possible? If so, how is this possible?

Re: [jboss-user] [JBoss Web Services Development] - CXF jms integration

We always assume that user already have this Queue/Topic deployed before webservice jms endpoint deployment or the jms deployment is deployed with jms endpoint, like how the MDB is deployed.+ Yes, you can provide initial test cases without this Queue/Topic abstraction in our SPI ;) -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/536888#536888] Start a new discussion in JBoss Web Services Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM Development] - How to provide my own transaction to jBPM?

by Guido Helmers

Guido Helmers [http://community.jboss.org/people/helmers] created the discussion "How to provide my own transaction to jBPM?" To view the discussion, visit: http://community.jboss.org/message/536887#536887 -------------------------------------------------------------- Hi, we're using jBPM 4.3, the jBPM tables are part of a bigger database schema, also containing our own tables. Our transactional service method looks like this: @Transactional public String create(Issue issue) { // http://community.jboss.org/message/536887#536887/1 http://community.jboss.org/message/536887#536887/1 (own stuff) issueDao.persist(issue); Map<String, Object> variables = new HashMap<String, Object>(); variables.put("ISSUE_ID", issue.getId()); // http://community.jboss.org/message/536887#536887/2 http://community.jboss.org/message/536887#536887/2 (jBPM stuff) ProcessInstance processInstance = executionService.startProcessInstanceByKey("PROCESS_KEY", variables); // http://community.jboss.org/message/536887#536887/3 http://community.jboss.org/message/536887#536887/3 (jBPM stuff) List list = taskService.createTaskQuery().processInstanceId(processInstance.getId()).list(); // ... etc } First we write some stuff to our own tables, then we tell jBPM to start a process. This is all done within one transactional method (I was hoping...). *jbpm.cfg.xml:* *tx.hibernate.cfg.xml:* *The problem...* The problem is that jBPM creates its own transaction, and does not take part in the transaction started by our own application (as you can see by writing an integration test that succeeds on steps [1] and [2], but uses a mockTaskService to throw an exception at [3] - what you see then is that our own tables are emptied (top-level transaction is rolled-back), but JBPM4_HIST_PROCINST is still filled, in other words [2] is executed in its own transaction and is not rolled back). I tried to remove the "standard-transaction-interceptor" from tx.hibernate.cfg.xml hoping that jBPM would magically participate in my own transaction, but that doesn't make jBPM very happy. Does anyone have an idea how I can tell jBPM to use my transaction, instead of starting its own? I read in the jBPM 4 developer's guide: http://docs.jboss.org/jbpm/v4/devguide/html_single/#d0e2216 http://docs.jboss.org/jbpm/v4/devguide/html_single/#d0e2216 that +"User provided transasctional resources such as JDBC connections or hibernate connections"+ is not yet available in jBPM4. I guess this feature is what I need... is it already implemented or in the pipeline? Does anyone know when this feature will be available, or if there is a workaround for it? This post is related to my earlier post on the fact that jbpm4 does not use the hibernate SessionFactory injected into it: https://community.jboss.org/thread/150549?tstart=0 https://community.jboss.org/thread/150549?tstart=0 In the test project attached to that issue, you can also see how transaction management in our application works... Perhaps the problem is solved as soon as the SessionFactory injection issue is solved?
