Re: [JBoss-user] Load-Balancing Problems

We took Sun's ServiceLocator example (at
http://java.sun.com/blueprints/corej2eepatterns/Patterns/ServiceLocator.html)
and extended it to cache not only the Context and the
Home, but the remote too. Reusing the remote (session
beans only...:) ) has the same effect, and you will
round robin happilly.
