Regarding RemoteException

Hi All,

I am using Solaris machine to start a remote MBean server. Then from another local machine I remotely bring the data from the remote server. I am successfully starting up the remote server, but when I start local server, I get the following exception:

 [java] Exception in thread "main" java.rmi.ServerError: Error occurred in s
erver thread; nested exception is:

Please advise, thanks
