Error looking up Topic when it's a resource reference in an EJB

Question

I have also posted this in the JNDI group, but as an after thought I thought
          it might be wise to post it here also.
          WLS 8.0
          Running in JBuilder for WLS
          I have a Stateless Session Bean in which I am looking up a JMS Connection
          Factory and a Topic. My first lookup consists of the following:
          InitialContext ctx = null;
          TopicConnectionFactory conFactory = null;
          ctx = new InitialContext();
          conFactory = (TopicConnectionFactory)
          ctx.lookup("java:comp/env/ConnectionFactory");
          That one works just fine. Later in the code i do the following lookup:
          Topic topic = null;
          topic = (Topic) ctx.lookup("java:comp/env/Topic");
          I get a NammingException. If I change the line to lookup the actuall Topic
          it works:
          topic = (Topic) ctx.lookup("jms/csrmh_refresh");
          Here is the Config.xml entries forthe JMS Configuration:
          <JMSConnectionFactory DefaultDeliveryMode="Non-Persistent"
          JNDIName="jms/ConnectionFactory" Name="JMS ConnFactory"
          Targets="myserver"/>
          <JMSServer Name="JMS Server" PagingStore="PagingStore"
          Store="PersistanceStore" Targets="myserver">
          <JMSTopic CreationTime="1065030416220"
          JNDIName="jms/csrmh_refresh" Name="RMH_Refresh"/>
          </JMSServer>
          Here is what is in the ejb.xml:
          <resource-ref>
          <description />
          <res-ref-name>ConnectionFactory</res-ref-name>
          <res-type>javax.jms.TopicConnectionFactory</res-type>
          <res-auth>Container</res-auth>
          </resource-ref>
          <resource-env-ref>
          <description />
          <resource-env-ref-name>Topic</resource-env-ref-name>
          <resource-env-ref-type>javax.jms.Topic</resource-env-ref-type>
          </resource-env-ref>
          Here is what is in the weblogic
          <reference-descriptor>
          <resource-description>
          <res-ref-name>ConnectionFactory</res-ref-name>
          <jndi-name>jms/ConnectionFactory</jndi-name>
          </resource-description>
          <resource-env-description>
          <res-env-ref-name>Topic</res-env-ref-name>
          <jndi-name>jms/csrmh_refresh</jndi-name>
          </resource-env-description>
          </reference-descriptor>
          Does anyone understand why the mapping doesn't work?
          Thanks,

As far as I can tell from your descriptors, what you're trying to do is OK.
          Could you post the stack trace for the exception you're getting, if you have
          one?
