Re: [jgroups-users] RpcDispatcher does not invoke remote method

Since you mention that the other RPCs get executed, I assume the cluster 
does form (that was going to be my first questions)... So only this 
specific RPC doesn't get called?

Note that the way you invoke the RPC is not very efficient, I suggest 
MethodLookup instead if you want better performance.

Which handle() method did you overwrite? MessageDispatcher or 
RpcDispatcher? Are you forwarding the call correctly (e.g. to super)?

Since I have no insight into your code I suggest write a small program 
that reproduces the problem and post it so I can take a look.
