look here, for generating EJBs http://xdoclet.sf.net and a Xdoclet-Petstore-Sample http://xpetstore.sf.net and Struts and EJBs http://developers.sun.com/events/techdays/codecamps/ THE LINK: Struts and Core J2EE Patterns Together Demo and https://strutsejb.dev.java.net/ i guess... now you have stuff... :-) cheers, PS: J2EE-Patterns-Book is great!
