Event to JMS to Event mapping behavior -------------------------------------- Key: SEAMJMS-16 URL: https://issues.jboss.org/browse/SEAMJMS-16 Project: Seam JMS Issue Type: Bug Reporter: John Ament While working on seam jms, I've noted the following behavior. java.lang.IllegalStateException: Singleton not set for BaseClassLoader@3479404a{vfs:///apps/jboss/jboss-6.0.0.Final/server/all/conf/jboss-service.xml} at org.jboss.weld.integration.provider.JBossSingletonProvider$EarSingleton.get(JBossSingletonProvider.java:59) [:6.0.0.Final] at org.jboss.weld.Container.instance(Container.java:58) [:6.0.0.Final] at org.jboss.weld.resolution.ResolvableBuilder.checkQualifier(ResolvableBuilder.java:209) [:6.0.0.Final] at org.jboss.weld.resolution.ResolvableBuilder.addQualifier(ResolvableBuilder.java:174) [:6.0.0.Final] at org.jboss.weld.resolution.ResolvableBuilder.addQualifierIfAbsent(ResolvableBuilder.java:184) [:6.0.0.Final] at org.jboss.weld.manager.BeanManagerImpl.resolveObserverMethods(BeanManagerImpl.java:464) [:6.0.0.Final] at org.jboss.weld.manager.BeanManagerImpl.fireEvent(BeanManagerImpl.java:604) [:6.0.0.Final] at org.jboss.weld.manager.BeanManagerImpl.fireEvent(BeanManagerImpl.java:598) [:6.0.0.Final] at org.jboss.seam.jms.bridge.IngressMessageListener.onMessage(IngressMessageListener.java:45) at org.hornetq.jms.client.JMSMessageListenerWrapper.onMessage(JMSMessageListenerWrapper.java:91) [:6.0.0.Final] at org.hornetq.core.client.impl.ClientConsumerImpl.callOnMessage(ClientConsumerImpl.java:822) [:6.0.0.Final] at org.hornetq.core.client.impl.ClientConsumerImpl.access$100(ClientConsumerImpl.java:46) [:6.0.0.Final] at org.hornetq.core.client.impl.ClientConsumerImpl$Runner.run(ClientConsumerImpl.java:940) [:6.0.0.Final] at org.hornetq.utils.OrderedExecutorFactory$OrderedExecutor$1.run(OrderedExecutorFactory.java:100) [:6.0.0.Final] at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) [:1.6.0_22] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) [:1.6.0_22] at java.lang.Thread.run(Thread.java:662) [:1.6.0_22] This exception occurs when trying to fire an event with the contents of a JMS message. The message listener in this case is instantiated from the portable extension and receives the bean manager as an argument in the constructor. I am able to get as far as reading the data from JMS, but when firing the second event the above exception occurs. I'm not certain that this is a Weld problem, but it seem slike a good place to start based on the packages shown.
