Webservice error

I have webservice provided by client. When I call the webservice I get Error: java.net.SocketTimeoutException: Read timed out
But the call is successful and data is being passed from my system to their system. Because of this SocketTimeoutException i am not able to capture the response from webservice. Is there any configuration that I need to set or any suggession.
Thank you in advance

set the following extended setting.
watt.net.timeout=1800.

Thanks Krishna that worked.
