Hello,

Calling one ejb from another is routine and done the same way as in any other client. To improve performance use Local Interfaces or ensure the Application Server is using pass-by-reference. If we are talking about Entity Beans then use the CMR features in EJB 2.0.

Here the WDJ manager bean will be calling the MartialArtist bean through its local interface.
