I want to use GUICE on the server side with the GWT 2.3 RequestFactory.
I have my class that extends the ServletModule with :
@Override
public void configureServlets() {
// RequestFactory servlet
bind(RequestFactoryServlet.class).in(Singleton.class);
serve("/gwtRequest").with(RequestFactoryServlet.class);
}
and in the web.xml I have added :
<filter>
<filter-name>guiceFilter</filter-name>
<filter-class>com.google.inject.servlet.GuiceFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>guiceFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
and I have the validation-api.XXX.jar referenced (as it is part of GWT)
When I run it (under Eclipse with the GWT plugin), it says:
jetty-6.1.x

I’m probably missing something but I don’t knwo where to look…
Thanks
Is validation-api.jar in your
war/WEB-INF/lib? (you say “referenced”, which might not be enough)
