Fault message "Exception while handling service request" or "signature mismatch" received when passing null parameter from .NET client to Web Service client application
 Technote (troubleshooting)
 
Problem(Abstract)
If you call a Web Services application and the signature of a method within the application requires one or more parameters, the caller must supply the parameters. Failure to supply the parameter or parameters will result in the Web Services application issuing a fault message or a "signature mismatch".
 
Cause
SOAP specifications (currently at http://www.w3.org/TR/SOAP/ ) allows SOAP applications (i.e., WebSphere Application Server Web Services) to reject requests with missing parameters.
 
Resolving the problem
Ensure that the method call passes the required parameters, or overload the method so that if no parameter is specified, the original method gets invoked with a null.
