    Problem with message redistribution in cluster

    srinivaas venkat Novice
      Hi I'm not able to run the queue-message-redistribution example that comes with Hornetq. I get the below exception with a failure message but I'm able to run the clustered-queue example successfully. Pls help.

       

      Environment details: Jboss 5.0.0.GA, HornetQ 2.0.0 CR2, Windows Xp (SP2)

          You are using HornetQ 2.0.0.CR2. Did you try using 2.0.0.GA instead to see if the example works?

            Jeff, Yes i tried with HornetQ GA version too and i get the same result. But I could see that the re-distribution working fine in my actual application where i have a cluster of queue nodes. It is only the example code that is not working.

              this is a rather old one but just in case someone comes across this NPE: setting

               

                  <broadcast-groups>

                      <broadcast-group name="my-broadcast-group">

                          <local-bind-address>127.0.0.1</local-bind-address>
                          <local-bind-port>8889</local-bind-port>

                          <local-bind-address>127.0.0.1</local-bind-address>

                          <local-bind-port>8888</local-bind-port>

                          ...

                      </broadcast-group>

                  </broadcast-groups>

               

                  <discovery-groups>

                      <discovery-group name="my-discovery-group">

                        <local-bind-address>127.0.0.1</local-bind-address>

                         ...

                      </discovery-group>

                  </discovery-groups>

              solved it - at least for me.
              You will see the cluster bridges being created.
