title: RestEasy - Unable to find MessageBodyReader?
body: <p>I've written a simple RestEasy client proxy to perform an iTunes search.  It looks like this:</p>
  
  <pre><code>@Path("/")
  public interface AppleAppStoreLookupClient {
  
      /**
       * Attempts to lookup an apple app store item by its ID
       * 
       * @param id
       *            The item ID
       * @return The app details
       */
      @GET
      @Path("/lookup")
      @Produces(value = { "text/javascript" })
      public AppleAppDetailsResponse lookupByID(@QueryParam("id") String id);
  }
  </code></pre>
  
  <p>My JSON model class is simple, as well.  In fact, for the first call all I want is the "resultCount" value, just to make sure connectivity works.</p>
  
  <pre><code>@XmlRootElement
  @XmlAccessorType(XmlAccessType.NONE)
  public class AppleAppDetailsResponse implements Serializable {
  
      private static final long serialVersionUID = 8881587082097337598L;
  
      @XmlElement
      private int resultCount = -1;
  
     ...getters and setters...
  
  }
  </code></pre>
  
  <p>However, when I run a simple test, I get the following Exception:</p>

  <p>I'm running RestEasy 2.3.6.  Any idea what could be causing such an error?</p>
