Got a little service and a runtime exception. Similar issues have been reported when the ErraiApp.properties maker was missing . This is not the case here - I put it in every module, just in case. Still the same run-time error.

The app war has two modules: web-shared and web-server. The web service classes are no missing, each of the module has a ErraiApp.properties. Any idea?

web-server module:

===================

@WebService//could be @Stateless too

public class PingService implements Ping{

    @Override public String ping() {  return "Ping OK!";}

}

web-shared module:

==================

@Path("/ping") @Produces(MediaType.APPLICATION_JSON)

public interface Ping {   

    @GET  @Path("/hello")    String ping();

}

web-app:

==================

...

@Inject private Caller<Ping> pingCaller;

@AfterInitialization   private void afterInitialization() {

        pingCaller.call((String response) -> {  Console.log(response);  }).ping();

}

... And I am getting:

========================================================
