In my thinking , I should only specify the queue and connecitonFactory and my message client and message server can comnunication to each other when I use jms message provider.
But in some situation , I have to configure activation specification on WebShpere despite I have configured the proper queue and connection factory.
The definition of activation specification as below , but I can't understand.
Can someone tell me the meaning and why I should configure activation specification even I have configured proper queue and connection factory?
You create a JMS activation specification if you want to use a message-driven bean to communicate with the default messaging provider through Java™ EE Connector Architecture (JCA) 1.5. JCA provides Java connectivity between application servers such as WebSphere® Application Server, and enterprise information systems. It provides a standardized way of integrating JMS providers with Java EE application servers, and provides a framework for exchanging data with enterprise systems, where data is transferred in the form of messages.
