Hi,
 
We 're using JBoss AS 5.1.0.GA and we have several deployed servers but not with the same version.
And when we invoke a method which does not exist in a server we 've got a NullPointer exception :
 
java.lang.NullPointerException

Is it possible to get and control the methods list of an ejb with the proxy
at the client side (in a interceptor for example).
 
Thanks in advance.
