GWT RemoteServiceServlet + Guice = GuiceRemoteServiceServlet

If you use Guice and GWT you'll probably find this handy:
GuiceRemoteServiceServlet is a wrapper servlet for GWT RPC utilizing Guice for managing RemoteService implementation object's lifecycle.

<servlet>
<servlet-name>GWT-RPCServlet</servlet-name>
<servlet-class>com.gc.gwt.server.GuiceRemoteServiceServlet</servlet-class>
<init-param>
<param-name>guice.module</param-name>
<param-value>com.test.guice.MyGuiceModule</param-value>
</init-param>
</servlet>

<servlet-mapping>
<servlet-name>GWT-RPCServlet</servlet-name>
<url-pattern>/GWT.rpc</url-pattern>
</servlet-mapping>

1. map all you remote service implementations in Guice Module
2. define and map GuiceRemoteServiceServlet as shown above
3. point ALL services to the same /GWT.rpc

Good luck.
