I think creating dual proxies gets too complicated and not being able to cast a proxy to EJBObject opens another can of worms No we definitely cannot do this. The EJB3 spec places no such restriction upon a business interface. Doing this would mean that perfectly valid EJBs (that execute on other people's platforms) do not execute on JBoss.
