Gabriel,
If you can use Guice-Servlet, running it through PersistFilter will start
the persistence service.
Managing things this way is fantastically simple, and you get the benefit of
request-scoped EntityManagers if you inject a provider of these into your
servlets.
public class GuiceServletModule extends ServletModule {
@Override
protected void configureServlets() {
install(new JpaPersistModule("p1"));
filter("/*").through(PersistFilter.class);
serve("/gwtRequest").with(AppRequestFactoryServlet.class);
}
Best regards,
Will
