hello ! I have a requirement in which i have a MDB in Weblogic which has to listen to messages coming in a TOPIC ( not a queue) through MQ series.Now i configured pub/sub and created a default queue manager.I ran runmqbrk e.t.c ..Also my bean in the weblogic is also looking Ok. When i tested this , i see the debug statement indicating that the publish to the topic is happening , but the MDB is not reacting( i put an SOP inside the onMEssage method ).My DESTINATION-JNDI name in the MDB weblogic-ejb-jar.xml matches with the name of the topic.Also the naming convention used for the topic and topic connection factory i mentioned correctly ( i presume ) as Topic - > MQ.Topics.(topicName) and factory as MQ.Factories.(factoryName). Now pls tell me what else do i need to do to make my MDB listen to the topic! Any methods to verify the topic getting published ? I am not able to see anything in the MQ explorer ! Rather i cant figure out whats happening ! Any help greatly appreciated ! Thanks !
