The 1.1. spec. section 14.3 says that EJB references "allow" the Bean
Provider to refer to the homes of other enterprise beans. I have not yet
found anywhere that says that Bean Providers must only use EJB references -
perhaps someone could enlighten me.
I think that using EJB references is good practice and would not mind if
they were made mandatory for all references but it is hard to see how this
could be achieved.

Hi Dan,
On re-reading the 1.1 spec I have to say your definitely correct and
it makes sense.
Without this the jndi names are a big dependency/management problem.
Thanks.
