Some errors when Using Locator and ServiceLocator in GWT2.4

Cannot validate this method because the domain mapping for the return type (XXXProxy) could not be resolved to a domain type Add @SuppressWarnings("requestfactory") to dismiss.

Starting with GWT 2.4, RequestFactory interfaces must be validated before they can be used by the RequestFactory server code or JVM-based clients. This document explains the mechanisms for validating those interfaces.

according to http://code.google.com/p/google-web-toolkit/wiki/RequestFactoryInterfaceValidation

I have done but came out some error in Proxy and Request class. like that:

Cannot validate this method because the domain mapping for the return   type (XXXProxy) could not be resolved to a domain type Add @SuppressWarnings("requestfactory") to dismiss.
Could not find domain method similar to java.lang.Integer countUsers()。

Help！I have passed for using Implementing a service in an entity class but can't pass Using Locator and ServiceLocator.

Mycode：

@ServiceName(value="UserProxy.class", locator="UserServiceLocator.class")
public interface UserServiceRequest extends RequestContext {

    Request<Integer> countUsers();
    Request<Void> generateUsers();
    Request<List<UserProxy>> findAllUsers();
    InstanceRequest<UserProxy, Void> persist();
    InstanceRequest<UserProxy, Void> remove();

}

@ProxyForName(value = "User.class", locator = "UserLocator.class")
public interface UserProxy extends EntityProxy {

    //...setter and getter

    EntityProxyId<UserProxy> stableId();

}

error [debug to use method on server]

You seem to be using the @ServiceName annotation incorrectly, in a couple of ways. If you want to mention a class literal, use @Service instead

@Service(value=MyServiceType.class, locator=MyServiceLocator.class)

If you want to use @ServiceName, you need the full package name

@ServiceName(value="com.company.server.MyServiceType", locator="com.company.gwt.MyServiceLocator")

The same is true for @ProxyFor and @ProxyForName, which you also seem to be using incorrectly.

In any case, you can't make the RequestContext's service point to a proxy - it should probably point to User, not UserProxy.
