    How get a MDB messages from a queue ? Who polls ?

    ameo Novice

      I have a question to MDB functionality.


      An MDB implements the MessageListener interface, so it uses the asynchronous onMessage() callback for JMS messages arriving in the queue.


      What does it mean ?


      How do the system (ejb-container ?) recognize, that a new message is placed in the queue ?  Does it polls agains the database queue and instantiate a new MDB ?
