I upgraded to JBossAS 4.2.0.GA and JBM1.3.0.GA and when I deploy my message handling MBean I get the following when it tries to create a jms session. I am not quite sure what this is even saying to me. Any insight as to what I need to do to fix this would be sincerely appreciated. 2007-06-03 11:04:37,988 INFO [com.eLynx.Messaging.MessageReceiver] EMail ServiceService MessageReceiver thread started... | 2007-06-03 11:04:37,988 INFO [com.eLynx.Messaging.MessageReceiver] EMail Service Service started. | 2007-06-03 11:04:37,988 DEBUG [com.eLynx.Service.EMail.EMailService] Started eLynx.EMail:service=EMailService | 2007-06-03 11:04:45,315 ERROR [com.eLynx.Messaging.MessageReceiver] Exception running MessageReceiver [thread id=115]. | java.lang.NullPointerException | at org.jboss.jms.client.container.FailoverValveInterceptor.invoke(FailoverValveInterceptor.java:86) | at org.jboss.aop.advice.PerInstanceInterceptor.invoke(PerInstanceInterceptor.java:105) | at org.jboss.jms.client.delegate.ClientConnectionDelegate$createSessionDelegate_6052335267724906805.invokeNext(ClientConnectionDelegate$createSessionDelegate_6052335267724906805.java) | at org.jboss.jms.client.container.ClosedInterceptor.invoke(ClosedInterceptor.java:170) | at org.jboss.aop.advice.PerInstanceInterceptor.invoke(PerInstanceInterceptor.java:105) | at org.jboss.jms.client.delegate.ClientConnectionDelegate$createSessionDelegate_6052335267724906805.invokeNext(ClientConnectionDelegate$createSessionDelegate_6052335267724906805.java) | at org.jboss.jms.client.delegate.ClientConnectionDelegate.createSessionDelegate(ClientConnectionDelegate.java) | at org.jboss.jms.client.JBossConnection.createSessionInternal(JBossConnection.java:269) | at org.jboss.jms.client.JBossConnection.createSession(JBossConnection.java:91) | at com.eLynx.Messaging.MessageReceiver.run(MessageReceiver.java:552) | 2007-06-03 11:04:46,424 ERROR [com.eLynx.Messaging.MessageReceiver] Exception closing JMS Session objects. | java.lang.NullPointerException | at org.jboss.jms.client.container.ClosedInterceptor.maintainRelatives(ClosedInterceptor.java:288) | at org.jboss.jms.client.container.ClosedInterceptor.invoke(ClosedInterceptor.java:165) | at org.jboss.aop.advice.PerInstanceInterceptor.invoke(PerInstanceInterceptor.java:105) | at org.jboss.jms.client.delegate.ClientConnectionDelegate$closing_N1847373599029068216.invokeNext(ClientConnectionDelegate$closing_N1847373599029068216.java) | at org.jboss.jms.client.delegate.ClientConnectionDelegate.closing(ClientConnectionDelegate.java) | at org.jboss.jms.client.JBossConnection.close(JBossConnection.java:131) | at com.eLynx.Messaging.MessageReceiver.run(MessageReceiver.java:629) Here is the code snippet where it occurs: // Lookup our JMS connection factory | InitialContext context = getInitialContext (); | QueueConnectionFactory connFactory = (QueueConnectionFactory) context | .lookup (getProperty (MessageReceiverProperties | .PropJMSConnectoryFactory)); | | // Get our jms connection | m_jmsConnection = connFactory.createQueueConnection (); | | // Get our jms session | m_jmssession = m_jmsConnection.createSession (false, Session.AUTO_ACKNOWLEDGE); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4050748#...
