Hi Jean, Here's another couple of articles on classloading in J2EE, which you might find interesting:
http://www.onjava.com/pub/a/onjava/2001/06/26/ejb.html http://www.onjava.com/pub/a/onjava/2001/07/25/ejb.html Bear in mind that these are over a year old though. I'm using Weblogic 6.0, which doesn't support the Manifest "Class-Path:" mentioned in the articles, so I have to either copy all library classes into the EJB jar or put the library jars on the Weblogic class path. This might be fixed in Weblogic 6.1 and/or 7.0, but I don't know. I would package your EJBs into a single EJB jar if they are logically part of the same application. If you use Local EJB objects, then I think you have to do this anyway. HTH.
