The server side of GWT application

Question

Is it possible to write a server side of GWT application in other languages then Java if yes how to use GWT-RPC mechanism, an sample code please

Thanks

Answer 1

Please read the GWT documentation Communication with the Server :

If you can run Java on the backend and are creating an interface for your application's server-side business logic, GWT RPC is probably your best choice. [...]

If your application talks to a server that cannot host Java servlets, or one that already uses another data format like JSON or XML, you can make HTTP requests to retrieve the data.

Answer 2

You can write your server in any language you choose, GWT is just JavaScript to be run in your users' browsers.

If you decide to go that route, you should look into using RequestFactory to communicate with your server instead of GWT-RPC, which is Java-specific. RequestFactory uses standard JSON, which any language can read/write.

Answer 3

Dont waist your time with GWT-RPC. It's bad. Use RequestFactory. I am surprised people are promoting GWT-RPC. It's a broken toy.
