Yes.. That's our ultimate goal :).

Cool.. Good Stuff..  Patching Rhino would be great for the start for our
POC as we discussed earlier.. But on the long run I doubt whether Rhino
people will accept this patch, since this will slow down the performance
of Rhino and also we are not implementing a defined annotations spec.
IMHO we might need to come up with a separate JavaScript annotations
parser, which we can use within the deployer. May be we can reuse the
rhino parser, but it'll also be quite trivial to write a new parser to
parse only these specific stuff. We can get some hints from this api.

I'm  wondering about the possibilities of writing this using javascript
it self. But the drawback in that case would be that we need to get the
help from Rhino at the deployment time to run it for us..

To extract the data from the annotation we can follow what is defined in
the PhP annotations. http://wso2.org/wiki/display/wsfphp/WSDL+Generation+API

Thanks,
Thilina
