Hi All,
I am new to Webservice and i am not trying to lookup for a web service, that is hosted on a remote server.
I have created a SOAP request and am trying to access the Web Service.
My Question is,
Whenever the Web service-hosted server is down, i want to log the request data as an XML file.

Basically i need to handle the Connection Refused exception..

any help/input is most appreciated..
