A Message Driven bean listener interface may define more than one message listener method. The resource adapter will determine which method will be invoked
So, In a typical development environment, The MDB has to define all the methods that are required by Message Listener interface (atleast provide empty implementation for an unwanted message listener method), and the resource adapter will decide on which method to choose?
But my question context is little different, I certainly understand that there are many message listeners based on messaging types. If the message listener interface (Like MessageListener interface imposes one method onMessage()), has many methods (like in POJI), MDB has to implement all those methods and the resource adapter will pick up one thats needed?
