QUESTION Re. Integrating TIBCO EMS with Weblogic 8.1 using MDB

Question

Hi All,
          I am trying to integrate TIBCO EMS 4.3.0 with Weblogic 8.1 SP6.
          I have created a topic "SIMPLE.TOPIC" on the EMS. I have configured the Foreign JMS Server as follows:
          Name: TIBCO JMSServer
          JNDI Initial Context Factory:com.tibco.tibjms.naming.TibjmsInitialContextFactory
          JNDI Connection URL:tibjmsnaming://emshost:emsport
          I have configured the connection factory as follows:
          Name: TIBCO JMSTopicConnectionFactory
          Local JNDI Name: TopicConnectionFactory.Local
          Remote JNDI Name:TopicConnectionFactory
          User Name:username to connect to EMS server
          Password::pssword to connect to EMS server
          My JMS destination is configured as follows:
          Name: Tibco JMS Destination
          Local JNDI Name:SIMPLE.TOPIC.LOCAL
          Remote JNDI Name:SIMPLE.TOPIC
          My weblogic-ejb-jar.xml consists of the following code:
                    <weblogic-ejb-jar>
            <weblogic-enterprise-bean>
              <ejb-name>SimpleTopicListener</ejb-name>
              <message-driven-descriptor>
                <pool>
                  <max-beans-in-free-pool>200</max-beans-in-free-pool>
                  <initial-beans-in-free-pool>20</initial-beans-in-free-pool>
                </pool>
                <destination-jndi-name>SIMPLE.TOPIC</destination-jndi-name>
               <connection-factory-jndi-name>TopicConnectionFactory</connection-factory-jndi-name>     
              </message-driven-descriptor>
              <enable-call-by-reference>True</enable-call-by-reference>
            </weblogic-enterprise-bean>
          </weblogic-ejb-jar>
                              The problem is, when I try to deploy this mdb, I get the following error:
          The Message-Driven EJB attempted to connect to the JMS destination with the JNDI name: SIMPLE.TOPIC. However, the object with the JNDI name: SIMPLE.TOPIC is not a JMS destination, or the destination found was of the wrong type (Topic or Queue).
          I have checked and double checked to make sure that the topic SIMPLE.TOPIC does exist on the EMS server.
          Does anyone know what is the issue here and how to resolve it?
          Many thanks!

Answer 1

(1) Check the standard ejb jar and make sure you've specified a topic destination type (the default is queue). For details, you can reference the WebLogic 9.0 MDB developer guide (the MDB dev guide was revised in 9.0 to include more detail than the 8.1 guide). Also, you might want to take a look at our integration/interop FAQ (again for 9.0 or later).
          (2) Change the weblogic-ejb-jar to reference the foreign local JNDI names - not the remote JNDI names.
          (3) Be careful about using the "." and "/" characters in local JNDI names - these have side-effects in JNDI (they force creation of subcontexts).
