hi
maybe you can find what you need at :
http://dev2dev.bea.com/devcenters/archive.html?technology=7 , do you need steps or sample of an application that show you how to build and configure an MDB in workshop ?
then you must take a look at documentation that come with bea workshop . i remember that there was some step by step tutorial for
ejb developemtn.
i have write a step by step tutorial on using MDB and a servlet/jsp client in Netbeans and Glassfish . maybe it can help you somehow.
