Every MDB type is associated with a particular Topic or Queue. When a client sends a JMS message, the server will allocate a correct MDB instance to service that request. In other words, an MDB is invisible to the client (which is why MDBs have no home or remote interfaces).
MDB has no client view (no home/component interface), therefore client cannot call MDB directly. Instead, client send message to JMS and JMS will deliver the message to MDB. [ January 30, 2006: Message edited by: Kengkaj Sathianpantarit ]

A JMS Topic or a queue is configured as a resource on the server under a JNDI name. A client has to do a JNDI look up to get a reference to a particular Topic or Queue and then post the message
OK ... One question. There is a EJB Server S1 that register a Queue with a name MX and there is a EJB Server S2 that register a Queue with the same name. If I look up with the JNDI name MX, what happen??
