Hi Ramya,

I think the server has shut down for some reasons ,because generally
java.net.ConnectException: Operation timed out: connect occurs only when you try to connect to the server when it is not up.I also see some of the reasons like unable to invoke etc.

I am not sure about this ,just find it out.
