Hi, I need your urgent help the problem described below, I have successfully deployed the EJB in weblogic 5.1, and I try to run a java client program to acces it, but upon invoking it, I got the following Unmarshal exception, it happened when the client tries to lookup for the home interface of the deployed EJB. Can someone offer me some help explaining what exactly this means? and any suggested solutions?

I can't say enough to thank you for your help.

Unmarshalled exception usually occurs when ur client and ur server are referring to different virsions of the same file.
u might have done something like compiled a file and not restarted the server or if u r using a browser client the try deleting ur Temporary Internet files.
