      Description

      The RESTEasy integration in Seam throws an exception when trying to serve an "empty" root resource. The resource looks like this:

      @Path("/")
      public class RootResource {
      @GET
      @Produces("text/plain")
      public String getResource()

      { return "Root resource"; }

      }

      The request path would be "http://localhost:8080/seam/resource/rest/". This path would be used for providing a resource for describing the additional resources published by the application, such as WADL or an AtomPub Service Description.

      This works fine under RESTEasy's own bootstrapper, without the Seam configuration handling.
