Configure Jersey MVC to serve Viewable without web.xml

Question

The important part is: without web.xml.

I already have a working JAX-RS app running on Glassfish 3.1.2.2 without a web.xml, configured purely by annotations.

The question is, how can I maintain the web.xml-less nirvana and still use Jersey MVC to serve static resources from the resources or webapp directory of my Maven .war project?

I see in many answers how can I do this with web.xml configuration, but nobody mentions how to map resources without the web.xml file.

Currently I have a ui.html file under the resources directory, a JAX-RS Application subclass and a resource class. No web.xml in the project and the following is working well:

@Path("/ui")
@GET
public Response ui() {
    String content = "Hello StackOverflow";
    return Response.ok(content).build();
}

While this one is failing with the IOException from the resolver:

   @Path("/ui")
   @GET
   public Response ui() {
      Viewable viewable = new Viewable("/ui.html");
      return Response.ok(viewable).build();
   }

java.io.IOException: The template name, /ui.html, could not be resolved to a fully qualified template name I also tried to specify it with a relative path, but that didn't work either.

The dependencies I'm using for Jersey are as follows:

     <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.18</version>
    </dependency>

I understand that a proper example project would be the best and willing to provide that if people are having a hard time figuring out what I'm talking about, just let me know.

Peter Metz, I believe this is possible by using the @WebFilter annotation on a class that extends org.glassfish.jersey.servlet.ServletContainer (Jersey 2.26):-

package com.myorg.myapp.config;

import javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;

import org.glassfish.jersey.servlet.ServletContainer;

@WebFilter(value = "/*", initParams = @WebInitParam(name = "javax.ws.rs.Application", value = "com.myorg.myapp.config.JerseyConfig"))
public class JerseyFilter extends ServletContainer {

    private static final long serialVersionUID = 1L;

}
