Hi all,

Problem scenario is: I am writing a Google Gadget. Data presented in the gadget will come from my deployed gwt app. I am planing to call the web service from JS to show the required data.

I need to know how I can expose the Service implementation class like GreetingServiceImpl(generated by default as sample in Eclipse GWT project) as web service.


Regards,
Vikram

Approach suggested http://code.google.com/p/gwtrpccommlayer/ will not work as, it is meant for the the consumption from java based client. Where as I am trying to invoke the web service through Java Script.

I either need to expose GreetingServiceImpl as a SOAP web service or as a REST full web service. I followed the tutorial given here. But instead of creating the Dynamic Web Project, I am trying this in the GWT project it self. But its giving the 404 error.

here is the code.



Servlet declaration in web.xml



And finally I HTML, having java script code to call the above service



Can anyone please give pointer on how can I solve this problem
