1. Use the Reflection technology to call EJB: http://www.theserverside.com/patterns/thread.jsp? Thread_id = 24019 The EJB call frame in the JDONSD framework is actually doing this, the specific principle is in my book "Java practical The "EJB Method Call Framework" section of the System Development Guide. 2.
