Marshalling argument exception

The server starts fine, but the error occurs when I try to add any job from the Client.I get the following error

java.rmi.MarshalException: error marshalling arguments; nested exception
is:

Pls give me the solution..

What is going on here is that one of the object that you are trying to send over RMI is an instance of the class snaq.db.CacheConnection, or (more likely) contains a reference to one somewhere.

This ain't going to work. The CacheConnection class is not serializable, and there's a good chance that cannot be made serializable.

A possible cure for this is to mark the field (or fields) of type CacheConnection in the classes you are trying to send as transient.
