Dear all I have a problem with JMS on JBoss 4.3.0. My queue works well but whenever after I reload my application I could not cast the queue object to my custom message object (CustomMessageBean ): ERROR: java.lang.ClassCastException: CustomMessageBean public void onMessage(Message message) { | try { | if (message instanceof ObjectMessage) { | String messageId = message.getJMSMessageID(); | ObjectMessage qObjectMessage = (ObjectMessage) message; | CustomMessageBean mailBeanJMS = (CustomMessageBean) qObjectMessage | .getObject(); | MailMgr receiverMailMgr = new MailMgr(); | rlog.debug("messageid: " + messageId); | ...... | | } | } catch (Exception e) { | System.out.println("ERROR: " + e.toString()); | } | } Here is configuration content for the queue: | <mbean code="org.jboss.jms.server.destination.QueueService" | name="jboss.messaging.destination:service=Queue,name=myQueue" | xmbean-dd="xmdesc/Queue-xmbean.xml"> | <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer</depends> | <depends>jboss.messaging:service=PostOffice</depends> | </mbean> To solve this problem, I have to restart JBoss Server every times I apply new source code! please help me solve this problem.
