I've set up a JBoss Messaging 1.4.4.GA configuration in a JBoss 4.2.2 server, using the provided ant script. I have a simple sample application that sets up a message consumer (via a spring message listener container) on a queue. This code worked perfectly with JBM 1.4.2 and earlier, but it seems that switching the client to the jboss-messaging-client jar of 1.4.4.GA breaks with the following exception: Failed to invoke; nested exception is java.lang.Exception: java.lang.NoSuchMethodError: org.jboss.remoting.Client.connect(Lorg/jboss/remoting/ConnectionListener;Ljava/util/Map;)V org.jboss.jms.exception.MessagingJMSException: Failed to invoke at org.jboss.jms.client.delegate.DelegateSupport.handleThrowable(DelegateSupport.java:271) at org.jboss.jms.client.delegate.ClientConnectionFactoryDelegate.org$jboss$jms$client$delegate$ClientConnectionFactoryDelegate$createConnectionDelegate$aop(ClientConnectionFactoryDelegate.java:198) at org.jboss.jms.client.delegate.ClientConnectionFactoryDelegate$createConnectionDelegate_N3019492359065420858.invokeNext(ClientConnectionFactoryDelegate$createConnectionDelegate_N3019492359065420858.java) at org.jboss.jms.client.container.StateCreationAspect.handleCreateConnectionDelegate(StateCreationAspect.java:80) at org.jboss.aop.advice.org.jboss.jms.client.container.StateCreationAspect_z_handleCreateConnectionDelegate_24216257.invoke(StateCreationAspect_z_handleCreateConnectionDelegate_24216257.java) at org.jboss.jms.client.delegate.ClientConnectionFactoryDelegate$createConnectionDelegate_N3019492359065420858.invokeNext(ClientConnectionFactoryDelegate$createConnectionDelegate_N3019492359065420858.java) at org.jboss.jms.client.delegate.ClientConnectionFactoryDelegate.createConnectionDelegate(ClientConnectionFactoryDelegate.java) at org.jboss.jms.client.JBossConnectionFactory.createConnectionInternal(JBossConnectionFactory.java:205) at org.jboss.jms.client.JBossConnectionFactory.createConnection(JBossConnectionFactory.java:87) at org.jboss.jms.client.JBossConnectionFactory.createConnection(JBossConnectionFactory.java:82) at org.springframework.jms.support.JmsAccessor.createConnection(JmsAccessor.java:184) at org.springframework.jms.listener.AbstractJmsListeningContainer.createSharedConnection(AbstractJmsListeningContainer.java:378) at org.springframework.jms.listener.AbstractJmsListeningContainer.refreshSharedConnection(AbstractJmsListeningContainer.java:363) at org.springframework.jms.listener.DefaultMessageListenerContainer.refreshConnectionUntilSuccessful(DefaultMessageListenerContainer.java:785) at org.springframework.jms.listener.DefaultMessageListenerContainer.recoverAfterListenerSetupFailure(DefaultMessageListenerContainer.java:767) at org.springframework.jms.listener.DefaultMessageListenerContainer$AsyncMessageListenerInvoker.run(DefaultMessageListenerContainer.java:898) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.NoSuchMethodError: org.jboss.remoting.Client.connect(Lorg/jboss/remoting/ConnectionListener;Ljava/util/Map;)V at org.jboss.jms.client.remoting.JMSRemotingConnection$1.run(JMSRemotingConnection.java:362) at java.security.AccessController.doPrivileged(Native Method) at org.jboss.jms.client.remoting.JMSRemotingConnection.start(JMSRemotingConnection.java:356) at org.jboss.jms.client.delegate.ClientConnectionFactoryDelegate.org$jboss$jms$client$delegate$ClientConnectionFactoryDelegate$createConnectionDelegate$aop(ClientConnectionFactoryDelegate.java:165) ... 15 more Switching back to the 1.4.2.GA client jar (still connecting to a 1.4.4 broker) seems to solve the problem. Am I using the wrong JBoss remoting library? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4237073#...
