"JBOSS Messaging Issue" To view the discussion, visit: http://community.jboss.org/message/552965#552965 -------------------------------------------------------------- I'm trying to bring up my hello world MDB in JBOSS 5.1 to see how i can get our messaging application into JBOSS 5.1 Messaging. The simple hellow world MDB gives me a wired issue. The MDB deployed fine and no problem in starting the JBOSS 5.1 AS. However when i tried to send a message from a client (servlet) which is also running in different JBOSS instance is always throwing the following exception while creating a session. 09:03:24,790 ERROR [STDERR] java.lang.NullPointerException 09:03:24,790 ERROR [STDERR] at org.jboss.jms.client.container.FailoverValveInterceptor.invoke(FailoverValveInterceptor.java:87) 09:03:24,790 ERROR [STDERR] at org.jboss.aop.advice.PerInstanceInterceptor.invoke(PerInstanceInterceptor.java:86) 09:03:24,791 ERROR [STDERR] at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 09:03:24,791 ERROR [STDERR] at org.jboss.jms.client.container.ClosedInterceptor.invoke(ClosedInterceptor.java:170) 09:03:24,791 ERROR [STDERR] at org.jboss.aop.advice.PerInstanceInterceptor.invoke(PerInstanceInterceptor.java:86) 09:03:24,791 ERROR [STDERR] at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 09:03:24,791 ERROR [STDERR] at org.jboss.jms.client.delegate.ClientConnectionDelegate.createSessionDelegate(ClientConnectionDelegate.java) 09:03:24,791 ERROR [STDERR] at org.jboss.jms.client.JBossConnection.createSessionInternal(JBossConnection.java:269) 09:03:24,791 ERROR [STDERR] at org.jboss.jms.client.JBossConnection.createQueueSession(JBossConnection.java:165) However when i try to connect from a standalone JAVA program the messaging works fine. I have no clue on what i should do now. The following are the configuration, ejb-jar.xml: <message-driven> <ejb-name>HelloWorldMDB</ejb-name> <ejb-class>com.yodlee.messaging.mdbs.HelloWorldMDB</ejb-class> <transaction-type>Container</transaction-type> <message-driven-destination> <destination-type>javax.jms.Queue</destination-type> <subscription-durability>Durable</subscription-durability></message-driven-destination> <resource-ref> <res-ref-name>HelloWorldMDB</res-ref-name> <res-type>javax.jms.QueueConnectionFactory</res-type> <res-auth>Container</res-auth></resource-ref> </message-driven> jboss.xml: <message-driven> <ejb-name>HelloWorldMDB</ejb-name> <destination-jndi-name>queue/HelloWorldQueue</destination-jndi-name> <mdb-user>mqm</mdb-user> <mdb-passwd>mqm</mdb-passwd> <resource-ref> <res-ref-name>HelloWorldMDB</res-ref-name> <jndi-name>MDBDLQCF</jndi-name> </resource-ref> </message-driven> The client code which i use it in servelt and stand alone program is exactly same like below, Properties env = new Properties(); String queueName = "queue/HelloWorldQueue"; String CFname = "ConnectionFactory"; env.put(Context.PROVIDER_URL, "jnp://....:1099"); env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); env .put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); try { InitialContext ctx = new InitialContext(env); System.out.println("Looking up for queue"); System.out.println(ctx.lookup(queueName).getClass().getName()); Queue destination = (Queue) ctx.lookup(queueName); System.out.println(destination.getQueueName()); System.out.println("Looking up for connection factory"); System.out.println(ctx.lookup(CFname).getClass().getName()); QueueConnectionFactory qcf = (QueueConnectionFactory)ctx.lookup(CFname); System.out.println("getting connection"); QueueConnection conn = qcf.createQueueConnection("abc", "abc"); System.out.println("creating session"); QueueSession queueSession = conn.createQueueSession(false,Session.AUTO_ACKNOWLEDGE); QueueSender sender = queueSession.createSender(destination); TextMessage message = queueSession.createTextMessage(); message.setText("Test Message"); System.out.println("Sending Message..."); sender.send(message); System.out.println("Finished Sending Message."); sender.close(); conn.close(); queueSession.close(); } catch (Exception e) { e.printStackTrace(); } Can you help me fixing this problem? Do you need any other information to debug? I'm using JBOSS Messaging 1.4.6 GA version. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/552965#552965] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2042]
