Hi Shammi, Thanks for the idea. I tried this out with activemq-client jar and several other jars. Still the casting problem exists. Further inspection showed me that there is another older version of jms osgi bundle (geronimo-spec-jms_1.1.0.rc4-wso2v1) in the carbon server. I think that this bundle causes the issue since this is an older version of jms and when we include the ActiveMQ jar to the lib the org.apache.activemq. ActiveMQConnectionFactory will not be able to cast into older version of javax.jms.TopicConnectionFactory.
So either we have to update the versions of existing jms bundles or we might have to find an older version of ActiveMQ jar which comply with geronimo-spec-jms_1.1.0.rc4 version. Appreciate your thoughts on the matter.
