servlets - My service is not reached when using guice + gwt -

i trying setup guice+gwt far cannot invoke service . async request fails.

here guice context listener:

import ne.projl.client.service.projservice; import ne.projl.server.projserviceimpl;  import com.google.inject.abstractmodule; import com.google.inject.guice; import com.google.inject.injector; import com.google.inject.persist.persistfilter; import com.google.inject.persist.jpa.jpapersistmodule; import com.google.inject.servlet.guiceservletcontextlistener; import com.google.inject.servlet.servletmodule;  public class myguiceservletconfig extends guiceservletcontextlistener {      @override     protected injector getinjector() {          return guice.createinjector(new servletmodule(){             @override             protected void configureservlets() {                 // todo auto-generated method stub                 install(new jpapersistmodule("projpunit"));                 filter("/*").through(persistfilter.class);                 serve("springgwtservices/*").with(projserviceimpl.class);                 //bind(projservice.class)              }          }, new abstractmodule(){              @override             protected void configure() {                 bind(projserviceimpl.class);              }          });     }  }

and async remote procedure call :

projservice.testdao(5, new asynccallback<void>(){              @override             public void onfailure(throwable caught) {                 // todo auto-generated method stub                 label des= new label("mer7 can");                 rootpanel.get().add(des);             }              @override             public void onsuccess(void result) {                 // todo auto-generated method stub                 label des= new label("merge1 can");                 rootpanel.get().add(des);             }           }); 

the caught error :

and projserviceasync interface :

public interface projserviceasync {     void greetserver(string input, asynccallback<string> callback)             throws illegalargumentexception;      void testdao(integer id, asynccallback<void> callback); } 

and relevant console output :

it looks missing application root in guiceservletconfig

in "myguiceservletconfig" try changing:

serve("springgwtservices/*").with(projserviceimpl.class);

to:

serve("/showcase/springgwtservices/*").with(projserviceimpl.class);

if doesn't work try adding "/test" on end instead of "/*" so:

serve("/showcase/springgwtservices/test").with(projserviceimpl.class);

so matches path in "projservice"

@remoteservicerelativepath("springgwtservices/test")
