HTTP method GET is not supported by this URL. (Jav

Question

im following one of the online tutorials for making rest api in java. I work in Eclipse 4.5.2. When i enter http://localhost:7001/ds2/api/v1/status i got mentioned in a title error. I included Jersey 1.19. Im using Oracle WebLogic Server 12c R2 (12.2.1). Starting page(index) works fine, but anything i would enter after /api/ gives me the same error.

My V1_status.java class:

package ds2.status;

import javax.ws.rs.*;
import javax.ws.rs.core.*;

@Path("/v1/status")
public class V1_status {
    @GET
    @Produces(MediaType.TEXT_HTML)
    public String returnTitle() {
        return "<p>Java Web Service</p>";
    }
}
