Subresource for target class has no jax-rs annotations

Question

I am trying to call a webservice method via a proxy but I have got an error message that says: "Subresource for target class has no jax-rs annotations.: org.jboss.resteasy.core.ServerResponse"

Here is my server class

@Path("/authorizationCheck")
public class AuthorizationRestService implements AuthorizationService  {

  @Override
    @Path("/webserviceTest")
    public Response webserviceTest(){
    TestDTO  x = new TestDTO();
    x.setFieldOne("ffff");
    x.setFieldTwo("gggg");
    Response res = Response.ok(x).build();
    return res;


    }
}

with a an interface like this

@Path("/authorizationCheck")
public interface AuthorizationService {

    @POST
    @Path("/webserviceTest")
    public Response webserviceTest();
}

and my return object wrapped in response

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class TestDTO {

    private String fieldOne;

    private String fieldTwo;

    public String getFieldOne() {
        return fieldOne;
    }

    public void setFieldOne(String fieldOne) {
        this.fieldOne = fieldOne;
    }

    public String getFieldTwo() {
        return fieldTwo;
    }

    public void setFieldTwo(String fieldTwo) {
        this.fieldTwo = fieldTwo;
    }



}

and finally my client class

@Stateful
@Scope(ScopeType.CONVERSATION)
@Name("authorizationCheckService")
public class AuthorizationCheckService {

    public void testWebservice(){
        RegisterBuiltin.register(ResteasyProviderFactory.getInstance());
        AuthorizationService  proxy = 
                ProxyFactory.create(AuthorizationService.class,
                        ApplicationConfig.WORKFLOWSERVER_URL + "services/authorizationCheck/webserviceTest");
        Response response =   proxy.webserviceTest();
        return;



    }
}

what I am doing wrong here , any help will be appreciated.

Answer 1

You have two annotations with webserviceTest() which are @POST and @Path.

Repeat BOTH the annotations in over ridden method in implemented class. That means add the @POST annotation to webserviceTest() method.

It should work then !

And here is the reason why it din't work.. without proper annotations in implementing class. Why java classes do not inherit annotations from implemented interfaces?

Answer 2

You can remove the @Path annotations on the implementation class and concrete method, and only annotate your interfaces, like this:

public class AuthorizationRestService implements AuthorizationService  {

    @Override
    public Response webserviceTest(){
        TestDTO  x = new TestDTO();
        x.setFieldOne("ffff");
        x.setFieldTwo("gggg");
        Response res = Response.ok(x).build();
        return res;
    }
}

Note: don't forget @Produces on your interface method to define your MIME type, such as MediaType.APPLICATION_XML

@Path("/authorizationCheck")
public interface AuthorizationService {

    @POST
    @Path("/webserviceTest")
    @Produces(MediaType.APPLICATION_XML)
    public Response webserviceTest();
}
