The use of java.lang.reflect.Proxy (or "no stubs") in EJBoss is really nice but
as I understand it you still need to dynamically or manually load the proxy
handlers to communicate back to the server. The java.lang.reflect.Proxy provides
you with a dynamic proxy generation on the client VM (providing your using JDK
1.3) but it doesn't eliminate the need for an InvocationHandler that smart
enough to connect to the server and handle things like transaction propagation
and communication of method invocations. Of course, I'm basing my assessment on
EJBoss model from a few months ago and this may have changed. If not, I don't
think your use of java.lang.reflect.Proxy buys you much.
