Here is the source code for the AllTypes bean. It's
actually supposed to be
the same as the one that jboss distribution is bundled with. package org.jboss.zol.testbean2.bean; import java.rmi.*; import javax.ejb.*; import java.util.Collection; import java.util.ArrayList; import org.jboss.zol.testbean.interfaces.StatefulSession;

As you've probably noticed I added some comments in this function, except this everything else is untouched from the original source code (including the client source code). I managed to deploy the AccountManager and the Account home and remote interfaces as well as the beans themselves.
