Hi All,

I have deployed a Web Service Application in WAS 5 and trying to invoke the Web Service.Iam getting the following Exception while trying to invoke the webservice from another application.

It works fine when Iam testing the Webservice using "Test with Web Service Explorer".

Any help on this is appreciated.

Thanks and Regards
Shiv

Following is the Stack Trace of the application.

Hi Shiv

Looking at the stack trace faultstring it seems like that the method invocation across the 2 applications is giving problems.
check the argument type on both the sides and have you done proper conversion for arguments for methods in your Facade/Delegate class.
I guess that may be the problem.

Hi Vikram

Thanks for your quick response.

I think the argument type is not a problem.Iam passing Strings as input parameter and getting the output as an array of the VO Object(which generally has getter and setter methods.).Moreover is works fine with the "Test with WebService Explorer".I wonder if its related to any jar file missing on the application server but no idea abt which jar file.

Thanks and Regards
Shiv
