Hey, I use maven2 for build. i package my application as an ear with the following structure: lib - with third parties jars. Server.jar Server-inf.jar Persistence.jar Server-startup.sar As you see I use sar in order to startup task when the application is loaded (I put dependency on the MBean in order to load after all ejb were loadeded ) The server-startup use classes in server and server-inf. The sar is loaded after all ejb were loaded , but I get ClassNotFound when I try in server-startup code to load classes from server.jar Any solution will be more than welcome.
