Its not a GWT limitation, its a browser restriction - Same Origin Policy. There are ways to workaround the limitation. In your case, you can setup a proxy server to forward the requests from one domain to another. Apache mod_proxy can help you with this.
For example, suppose you have http://rpc.example.com/MyRpcService and http://UI.AnotherExample.com/. You can setup Apache to forward requests from http://UI.AnotherExample.com/services/* to rpc.example.com. Then, you'd configure your RPC client to send requests to "../services/MyRpcService". Since the browser is sending the request to the same domain, everything works fine. It works well (we have our production systems working that way), but I don't recommend using it unless you have run out of options. --Sri On 1 June 2010 11:35, Umesh Adtani <adt...@gmail.com> wrote: > I have a RPC servlet that I would like to make available to other GWT > application developers.
