    java.lang.ClassCastException

    Naveen Verma Newbie

      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.

          Are you attempting to use the CF outside of JBoss?

            Sorry for the confusion..yes we are using CF outside AppServer

              The JMS/JCA adapter is not meant to be used outside of the application server. It is specifically for EJB and Servlets that need JMS XA. For JMS outside of the server you need to use something like the following:

              
              QueueConnectionFactory qcf = (QueueConnectionFactory)ctx.lookup("ConnectionFactory");
              


              The "ConnectionFactory" binding is the generic ConnectionFactory meant to be used outside of the container. Also, you should remove the

              <use-java-context>false</use-java-context>
              


              From you *-ds.xml file.

                Based on the suggestions, I did all suggested changed. Now I am getting javax.naming.NameNotFoundException: jms not bound

                Infact, can you please suggest how do I create my own connection factory? I have my MDB

                  I don't know about frustrated, but you're getting very confused. :-)

                  And it is very difficult to help when you post "random"/incomplete information.
                  Normally, I'd ignore this post as unanswerable, instead I'm going to *guess*
                  what you problem is.

                  Posting wrong/irrelevant information is almost certainly a sign that you don't know
                  what you doing and that you should revert to the examples in the documentation
                  for comparison.

                  1) Always show full stacktraces (I've got no idea where your NameNotFound occurs)

                  2) Why do you show mdb config and then talk about client code?

                  3) The JBossMQ connnection factories are bound at "ConnectionFactory"
                  by default. If you want to alias this then look at deploy/jms/uil2-service.xml
                  which contains some different types of jndi aliases.

                  Anyway, your original problem is resolved. This is really a JNDI question not a
                  JMS question (like 50% of the questions in the forum it is offtopic).

                  If you don't understand how to configure/use JNDI then you've got no chance.
