JMX and MBean serialVersionUID problem

Hi.

I have instrumented a web based application with MBeans and also written its own JMX connector server that will allow external clients to connect to it. I am deploying the application on Websphere Application Server version 5.x. Now the problem is that when I connect using MC4J console, it throws the following error message :-
