How to integrate GWT or Vaadin with Play Framework 2.0

gwt, playframework-2.0, vaadin

Solution

GWT and Play2 can work together seamlessly, just as GWT can be used with python and go backends.

Using GWT with Play2 has two parts, serving static files and client-server communication.

For the GWT produced static files (js, css, img..) you can just add them to the Play2 `public` directory, and they will be accessible based on the routes configuration.

For client-server communication your best bet is using a pure json-rest approach, as request-factory, gwt-rpc have some dependency on J2EE servlets.

There are plenty examples of providing a json/REST api with Play2, and plenty examples of interacting with json/REST APIs with GWT.

Problem

Is is possible to implement the client side of a Play Framework 2.x web application using GWT or Vaadin? Play 1.x has a special module that provides GWT integration, but I can not find examples of the use of these technologies together in Play 2.x version. Can these technologies be integrated? Is there a module, or must some other approach be used?
