GUI clients do not benefit from local interfaces.

There's nothing you need to do on the web-tier configuration.
What kinds of programs are candidate benificiaries of local interfaces?
Sounds like JSPs and servlets are. Anything else?
Anybody know of any example source code?
EJBs that call other EJBs will also benefit from the local calls. The savings you get are:
1. Pass by reference (memory use)
2. Not over the wire (delay)
3. No PortableRemoteObject (delay)
Since all but the simplest applications have complex (chained) EJB logic, most applications will benefit from the middle-tier optimizations.
