requestfactory #7

Hi John,

Following your advice, I try to use requestfactory for exchanging eo.

It uses another servlet so I have added in web.xml :

<servlet>
       <servlet-name>requestFactoryServlet</servlet-name>
       <servletclass>
         com.google.web.bindery.requestfactory.server.RequestFactoryServlet
       </servletclas>
</servlet>

<servlet-mapping>
       <servlet-name>requestFactoryServlet</servlet-name>
        <url-pattern>/gwtRequest</url-pattern>
</servlet-mapping>

In my gwt script I have something like :
       MyRequestFactory requestFactory = GWT.create(MyRequestFactory.class);
       requestFactory.initialize(eventBus);
       MovieRequest movieReq = requestFactory.movieRequest();
       Request<MovieProxy> req = movieReq.read("a super movie");
       req.fire(new Receiver<MovieProxy>() {
            @Override
            public void onSuccess(MovieProxy movie) {

            }
...

The method "read" is never reach in server EO Movie and I get an exception.

How can I be sure that requestFactoryServlet is started in WO environment and 
what is going to take care of annotation used in MovieProxy ? 
@ProxyFor(your.app.server.eo.Movie.class)

Thanks your your help.
Pierre
