How can I call a GWT RPC method on a server from a non GWT (but Java) gapplication?

Question

I have a regular Java application and want to access an GWT RPC endpoint. Any idea how to make this happen? My GWT application is on a GAE/J and I could use REST for example

GWT SyncProxy allows you to access GWT RPC services (e.g methods) from pure Java (not JSNI) code.

See http://www.gdevelop.com/w/blog/2010/01/10/testing-gwt-rpc-services/ for details.
