Hi Folks,

I am making an RMI call to a remost host (Weblogic) and am getting the following nested exceptions
Java Syntax (Toggle Plain Text) 
  1. weblogic.rjvm.PeerGoneException: ; nested exception is: 
  2. 	java.rmi.UnmarshalException: Incoming message header or abbreviation processing failed ; nested exception is:

  34. 	at weblogic.rjvm.ConnectionManager.dispatch(ConnectionManager.java:748)

When I try to connect to remote host (A) using RMI call, it works fine, but when I try to connect to remost host (B) using RMI call, it gives me the above exception.

Can some one suggest...

Thanks.

you could start your own thread instead of just re-opening a thread that's been dead for almost a year

s_damry,

The problem was that the classes on the server was different than the classes on the client side.

You need to make sure to reference the same class (from the same built) in your client side.

That's all you need to do.
