Question

After deploying the ejb project and the web project on glassfish and when I run my webservice PatientService I have HTTP Status 404 - Not Found. this is my code :
import java.util.List;
import javax.inject.Inject;
import javax.inject.Named;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.UriInfo;
#Named
#Path("/patient")
#Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
#Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public class PatientService {
#Inject
private PatientEntityFacade patientEntityFacade;
#Context
private UriInfo uriInfo;
#GET()
#Path("/findALL")
public List<PatientEntity> findAll(){
return patientEntityFacade.findAll();
}
}
