javax.ws.rs.NotFoundException: Could not find reso

I found this same question in here few times, but I couldn't find an answer to that.

When I run my application, Im getting the following error

javax.ws.rs.NotFoundException: Could not find resource for full path: http://localhost:8080/RemoteQuartzScheduler/rest/TestClass/hello

Here is the pom file of the project (I only added the main parts)

Here is my Test.java class

@Path("/TestClass")
public class Test implements Serializable{

  private static final long serialVersionUID = -262701666015379272L;

  @GET
  @Path("/hello")
  public Response heloMessage() {

    String result = "Hello Word!!!!!!!!!";

    return Response.status(200).entity(result).build();
  }   
}

Please tell me where did I do wrong?? Thanks in advance

I haven't gotten a chance to test your version (with the web.xml), and honestly I don't work much with xml when I do use Resteasy, so I won't go trying to explain what is wrong (if anything) with the web.xml.

But when working with an javax.xs.rs.core.Application subclass, we can define an @ApplicationPath("/path") annotation. This defines a servlet for our JAX-RS application, with the url mapping of /path/*. This is specified in the JAX-RS spec.

You can see more here about this deployment option, as well as others, in section 2.3.2 Configuration - Servlet. This is a 1.1 spec (you are using 2.0), but the deployment options are similar. I just couldn't find an html link to the 2.0. You can download the pdf though from here.

You can also read more about deployments with Resteasy here in the documentation.

But basically, what this deployment option does is scan for annotations of @Path, @Provider, etc for the application. The reason is that JAX-RS will first look for classes and object in overridden getClasses() and getSingletons(), respectively. If then return empty sets, this tell JAX-RS to do scanning (per the spec).
