[jboss-as7-dev] Invoking remote EJBs on JBoss AS 4/5/6 from JBoss AS 7

[Stephen Coy]

So,

The security context definitely seems to make it across the wire. I can get the correct caller principal and role based method permissions are behaving as expected.

Transactions are a different story however. I will dig deeper, because I think this will be useful for those that want/need to be able to perform gradual migrations.

Cheers,

Steve C
