I used the SOAP UI to send in a request to the web service end point and I got a response back. The method just returns the string passed in. Here is the response:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<ReturnStringResponse xmlns="AddUser">
<ReturnStringResult>Hello Monisha</ReturnStringResult>
</ReturnStringResponse>
</soap:Body>
</soap:Envelope>

Which implies that the webservice works fine. Would appreciate if you can please give me further debugging assistance on why it fails when executed from the bpms server.

Thanks,

Monisha
