"java.lang.NullPointerException on JBoss 6 M2" To view the discussion, visit: http://community.jboss.org/message/536677#536677 -------------------------------------------------------------- I am trying to deploy 2 MDBs in a standalone XP machine running JBoss 6 M2. I am getting the following exceptions in my server.log I do have a ejb-jar.xml but I gather I do not need one since I have EJB3, but I do have session beans that are from EJB 2.0. I have configured an Mysql datasource and necessary queues in the appropriate xml files, but it is apparent I am not doing something right somewhere. How can I solve this problem? Any pointers in resolving this issue are appreciated. Thanks in advance. The errors are below: 2010-04-09 16:47:20,661 WARN [org.jboss.resource.adapter.jms.inflow.JmsActivation] (pool-1-thread-3) Failure in jms activation org.jboss.resource.adapter.jms.inflow.jmsactivations...@40d447(ra=org.jboss.resource.adapter.jms.jmsresourceadap...@967df destination=queue/jissuetrackerLog destinationType=null tx=true durable=false reconnect=10 provider=DefaultJMSProvider user=null maxMessages=1 minSession=1 maxSession=15 keepAlive=30000 useDLQ=true DLQHandler=org.jboss.resource.adapter.jms.inflow.dlq.GenericDLQHandler DLQJndiName=queue/DLQ DLQUser=null DLQMaxResent=10): java.lang.NullPointerException at org.jboss.jms.client.container.ConnectionAspect.getConnectionState(ConnectionAspect.java:252) at org.jboss.jms.client.container.ConnectionAspect.handleSetExceptionListener(ConnectionAspect.java:117) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.jboss.aop.advice.PerInstanceAdvice.invoke(PerInstanceAdvice.java:122) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.jms.client.container.ClosedInterceptor.invoke(ClosedInterceptor.java:170) at org.jboss.aop.advice.PerInstanceInterceptor.invoke(PerInstanceInterceptor.java:86) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.jms.client.delegate.ClientConnectionDelegate.setExceptionListener(ClientConnectionDelegate.java) at org.jboss.jms.client.JBossConnection.setExceptionListener(JBossConnection.java:116) at org.jboss.resource.adapter.jms.inflow.dlq.AbstractDLQHandler.setupDLQConnection(AbstractDLQHandler.java:142) at org.jboss.resource.adapter.jms.inflow.dlq.AbstractDLQHandler.setup(AbstractDLQHandler.java:83) at org.jboss.resource.adapter.jms.inflow.dlq.JBossMQDLQHandler.setup(JBossMQDLQHandler.java:48) at org.jboss.resource.adapter.jms.inflow.JmsActivation.setupDLQ(JmsActivation.java:414) at org.jboss.resource.adapter.jms.inflow.JmsActivation.setup(JmsActivation.java:352) at org.jboss.resource.adapter.jms.inflow.JmsActivation$SetupActivation.run(JmsActivation.java:730) at org.jboss.resource.work.WorkWrapper.run(WorkWrapper.java:172) at org.jboss.threads.SimpleDirectExecutor.execute(SimpleDirectExecutor.java:33) at org.jboss.threads.QueueExecutor.runTask(QueueExecutor.java:780) at org.jboss.threads.QueueExecutor.access$100(QueueExecutor.java:45) at org.jboss.threads.QueueExecutor$Worker.run(QueueExecutor.java:800) at java.lang.Thread.run(Thread.java:619) at org.jboss.threads.JBossThread.run(JBossThread.java:122) --------------------------------------------------------------------------------------- The following is the code of one of the MDBs.
