In order to get the restriction up and working, you have to define a
different code base for your beans, which few vendors actually do. That
would be specified in your java.policy file, not in the EJB server
itself (there's no API for the container to do that).
Funny, but EJB actually has to go the extra step to place these
restrictions, and I don't think anybody actually took the time (or ever
will) to do that.
