Re: RequestFactory ServiceLocator use Guice

See https://github.com/tbroyer/gwt-maven-archetypes/tree/master/guice-rf-activities/src/main/resources/archetype-resources/__rootArtifactId__-server/src/main/java

The RequestFactoryServlet is instantiated by Guice (configured in the ServletContextListener); the ServiceLayerDecorators are instantiated by Guice too and injected into the RequestFactoryServlet constructor. Here I'm using a ServiceLayerDecorator that'll use Guice to create the Locators and ServiceLocators, and there's a GuiceServiceLocator that RequestContext can't point to to have their services created by Guice.

Hi there, 

I wish to use Guice to inject objects in ServiceLocator class.  I am having trouble getting it done, end up with injector.injectMembers(), which I should avoid.

Any suggestion how I use Guice in the code below so that my object can be injected into either MyServiceLocator or MyService.

public class MyServiceLocator implements ServiceLocator {

    // field injection does not work here, because GWT internal code is creating ServiceLocator using class.newInstance(), which expects non-argument constructor.

    @Override

    public Object getInstance(Class<?> clazz) {       

        if (clazz.equals(MyService.class)) return new MyService();    // cannot use injection because I am creating the object using new()

        else return null;

    }

}

Thanks,

Yan
