Abstract:

A system, method, and program product, in which a stateful EJB session bean is used as the front end to client calls. In this configuration, a queue is represented by a session bean instance. âPutâ and âgetâ are called on the relevant session bean instances. Thus, for example, a client, instead of first finding a home for a given type of OMs then calling âputâ on the home to send out messages, will find a session bean home, create a session bean instance corresponding to a queue, and call âputâ on the bean instance to send messages. In this manner, the message queue can be managed using standard EJB techniques.
