    jndi jms topic lookup fails while deployment

    Prasad Deshpande Expert

      Hi,

       

      I have defined a topic in hornetq & referring that topic using some other name in my ejb, it throws me following error.

       

      15:10:07,604 ERROR (DeploymentScanner-threads - 1) {"Composite operation failed and was rolled back. Steps that failed:" => {"Operation step-2" => {"Services with missing/unavailable dependencies" => ["jboss.deployment.subunit.\"efp.ear\".\"efprocess.jar\".jndiDependencyService missing ","jboss.naming.context.java.comp.efp.efprocess.ErrorLoggerHandler.env/jms/ErrorTopic.jboss.deployment.subunit.\"efp.ear\".\"efprocess.jar\".component.ErrorLoggerHandler.9 missing "]}}}

       

       

      Annotation is like below :

       

      @Resource(name="jms/ErrorTopic", type=Topic.class, mappedName="topic/efpErrorTopic")

      public class ErrorLoggerHandlerBean implements ErrorLoggerHandlerLocal {

      ...........

      }

       

       

      I can see all my topics & queus are deployed from following logs:

       

      15:09:54,213 INFO  [org.hornetq.core.server.impl.HornetQServerImpl] (MSC service thread 1-8) trying to deploy queue jms.topic.AuditTopic

      15:09:54,229 INFO  [org.hornetq.core.server.impl.HornetQServerImpl] (MSC service thread 1-4) trying to deploy queue jms.topic.ErrorTopic

      15:09:54,276 INFO  [org.hornetq.core.server.impl.HornetQServerImpl] (MSC service thread 1-2) trying to deploy queue jms.queue.ActiveActivityQueue

       

      Does anyone have any clues as why this is failing (that too while ejb deployment.. actual lookup is way too far.)?

          Aparently, mappedName should start with "java:/". So tag becomes mappedName="java:/topic/efpErrorTopic", then it works fine.

           

          A small question still if someone can answer,

           

          what is a default namespace in AS7? So suppose, I don't specify "java:/", then where exactly jndi lookup performed? I guess in earlier versions it was "java:comp/env", I tried in AS7 for com/env, but it didn't work for  me. Could anyone answer please?

            Hmm, I'll have to see what's going on here. I mean, I'll have to check to what namespace the queue/topics are bound by default when you have

             

            <jms-queue name="testQueue">
                             <entry name="queue/test"/>
                          </jms-queue>
            

             

            From what you say, it looks like they are by default bound to java: namespace.

              Yes, I had look at this discussion over weekned, but I thought since the issue is not yet fixed, it still allows to bind to java:/ namespace. I've created a small piece of code to expose JNDI tree, & I found that when you deploy queue/topic like

               

              <jms-queue name="testQueue">
                <entry name="queue/test"/>
              </jms-queue>
              <jms-topic name="testTopic">
                <entry name="topic/testTopic"/>
              </jms-topic>

              It get's bound under "java:/queue" & "java:/topic" namespace. This is exactly how, I was able to proceed with the error in the first post. But since, http://lists.jboss.org/pipermail/jboss-as7-dev/2011-July/002890.html is going to change the way it is now, I'll have to wait until this is being fixed.

                This is fixed as part of AS7-1210 and is available in latest AS7 nightly builds.

                  Strange enough, If I specify as follows in destination configuration:

                  <jms-queue name="testQueue">
                    <entry name="queue/testQueue"/>
                  </jms-queue>
                  <jms-topic name="testTopic">
                    <entry name="topic/testTopic"/>
                  </jms-topic>

                  I get message that it is bound to "java:jboss/jms/queue/testQueue" & "java:jboss/jms/topic/testTopic" resp. but when I see it in JNDI It shows in "java:jboss/queue/testQueue" & "java:jboss/topic/testTopic" resp.

                   

                  Not sure why..

                   

                  so I explicitely have to specify as :

                   

                  <jms-queue name="testQueue">
                    <entry name="java:jboss/jms/queue/testQueue"/>
                  </jms-queue>
                  <jms-topic name="testTopic">
                    <entry name="
                  java:jboss/jms/topic/testTopic"/>
                  </jms-topic>

                   

                  need to dig-in more..

                    Which JNDI tree? The one available from the command line client?

                      Not really, I created a sample servlet that browses JNDI, until AS7 comesup with JNDI console, it will be helpful to me...
