[mashup-dev] Annotating JavaScript to make JavaScript Web services Deployment easy

[Deepal Jayasinghe]

It is very cool feature to have JS2WSDL support , and annotation will
help to support that. What you just need to do is populate the
AxisService correctly then at the run time you would get the right wsdl.

Thanks
