Hi all,
I was going through the EJB 2.0 pfd 2 and was wondering about
the section which mentions that a remote interface lookup will
require a PortableRemoteObject.narrow while the a local interface
lookup can be just cast (normal java cast) to the home interface.
But now - I have the feeling that ejb-links are redundant. The purpose
of an ejb-link was to establish fast, easy co-located lookups between
EJBs in the same jvm - which is exactly what local interfaces are
supposed to achieve - but with supposedly less overhead plus the
ability to pass objects by reference instead of by value. But it seems
like now ejb-links themselves are now used to look up local home
interfaces.
<spec>
Context initialContext = new InitialContext();
CartHome cartHome = (CartHome)
initialContext.lookup("java:comp/env/ejb/cart");
</spec>
Comments on why this seems to be superfluous? Or rather if it
is so (as I believe)? And what is the role of ejb-links w.r.t remote
and local interfaces in PFD2?
