Webservice task not working

[kavi]

Hi ,

I want to use a webservice task.
Being new to Activiti, to check for sample i tried an eg from "activiti\workspace\activiti-cxf-examples\src\test\resources\org\activiti\engine\impl\webservice"
I zipped the folder and deployed it.
But when i click start instance in process it says "05300003 Wrapped Exception (with status template): null" error.
Why is it so?

What am i missing?

Thanks,
kavi

Do you have a longer stacktrace, the error you have there is very generic.
