    i think that it is very useful to use JMS.

  3. callbacks from EJB[ Go to top ]

    Hi, There are in principle three solutions to this problem: 1. The client creates a temporary JMS destination, it passes the JNDI name of this destination to the EJB and then the EJB can send a callback message to the JMS destination (the client listens to that one in a separate thread). 2. The client creates an RMI object (implementing java.rmi.Remote) and registers it with the EJB. 3. The client implements a JAX-RPC endpoint to which the EJB will send a SOAP callback message. Greetings, Sorin
