Hi Venkat, WSDL 2.0 is not supported yet. We do not have a working WSDL 2.0 reader. However the codegen engine works off WOM (not WSDL4J) hence if the WSDL 2.0 reader is done, we are all set to generate code for it :-)
And yes, it is perfectly possible for the codegen to generate code for the HTTP binding. We already have the client API support for doing the REST calls and it should be a matter of putting in a correct template ! -- Ajith Ranabahu
