[Messaging, JMS & JBossMQ] - java.lang.ClassCastException
by vermanaveen
Please help.
I am using jboss-4.0.5.GA and have defined JMS connection factories and queues. Everything is fine in the AppServer and all MDB's are deployed and work fine. I get a ClassCastException while trying to do a lookup for the QueueConnectionFactory. The class being returned by JBoss is org.jboss.resource.adapter.jms.JmsConnectionFactoryImpl inline to javax.jms.QueueConnectionFactory which is what i expect to get.
The connectionfactory is defined as below in the jms-ds.xml file in jboss..
| --------------------------------------------------------------------------------
|
| <tx-connection-factory>
| <jndi-name>jms/novaJMSConnectionFactory</jndi-name>
| <xa-transaction/>
| <use-java-context>false</use-java-context>
| <track-connection-by-tx/>
| <rar-name>jms-ra.rar</rar-name>
| <connection-definition>org.jboss.resource.adapter.jms.JmsConnectionFactory</connection-definition>
| <security-domain-and-application>JmsXARealm</security-domain-and-application>
| </tx-connection-factory>
|
| --------------------------------------------------------------------------------
|
The client program does a simple lookup for the connection factory and the relevent section is as shown below..
queueConnectionFactory = (javax.jms.QueueConnectionFactory) jndiContext.lookup("jms/novaJMSConnectionFactory");
The above line fails with a ClassCastException because JBoss is not returning the connection factory typecasted to javax.jms.QueueConnectionFactory; but is returning an object to javax.naming.Reference.
Below is my ejb-jar.xml that I use for creating the EAR file.

[Management, JMX/JBoss] - Re: how to get mbean to deploy after ejb is bound
by mazz＠jboss.com
I've had to do this very thing in my app. The easist thing to do is:
1) In your MBean, do not do anything that requires the EJBs in your start() method (that is, do not expect the EJBs to be deployed when your MBean is deployed).
2) Create a "reallyStartNow" method in your MBean - this is when it can perform its startup routines that require the EJBs to be deployed
3) if you don't already have a war in your ear, create one
4) create a StartupServlet and make sure it is loaded at startup (defined in web.xml appropriately)
5) in your StartupServlet's init() method, use JMX to find your MBean and invoke the "reallyStartNow" method.
MBeans are deployed first, then EJBs within your EAR, then Webapps within your EAR are started last. So, your init() method is called at a point in time when you know everything else is ready.
This works perfectly for me.
