Resource config error java REST project

Question

I'm following a tutorial for creating a RESTful java web service. I'm at the point where I have a GET service test method created, however when I try to call it I get the exception:

"SEVERE: StandardWrapper.Throwable com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes"

I googled this error message and read other posts but could not seem to get a working solution from what I read. My web.xml looks like this.

    <servlet-mapping>
        <servlet-name>Jersey REST Service</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>


</web-app>

My source code class looks like this:

package com.zcservices.rest.status;

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

@Path("/v1/status")
class V1_status
{
    @GET
    @Produces(MediaType.TEXT_HTML)
    public String returnTitle()
    {
        return "<p>The webservice is operational</p>";
    }

}

My project structure looks like this:

Full Stack Error: (This occurs when I start the server, yet it will still startup successfully and I will see this error when trying to navigate to the page to exercise the method in the above source code).

Any help would be appreciated, thank you.

Answer 1

Your setup looks OK. What strikes me though is that your class has default access. Try making it public:

@Path("/v1/status")
public class V1_status
