[jboss-dev-forums] [EJB 3.0 Development] New message: "How get a MDB messages from a queue ? Who polls ?"

JBoss development, A new message was posted in the thread "How get a MDB messages from a queue ? Who polls ?": http://community.jboss.org/message/527444#527444 Author : Murat Yanik Profile : http://community.jboss.org/people/ameo Message: -------------------------------------------------------------- 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 ?   Greetings -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/527444#527444
