RequestFactory ServiceLocator use 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
