Sergey Beryozkin commented on CXF-3248:
---------------------------------------

Glen, how do you run this example in CXF ? Are you sure you haven't specified NotFoundExceptionMapper as a service bean ?

>             Project: CXF
>          Issue Type: Bug
>          Components: JAX-RS
>    Affects Versions: 2.3.2
>            Reporter: Glen Mazza
>            Priority: Minor

> Example 7-1 of the JAX-RS book samples (see https://issues.apache.org/jira/browse/CXF-3247) is returning a unclear error message when it processes the following ExceptionMapper:
> @Provider
> public class NotFoundExceptionMapper implements ExceptionMapper<NotFoundException>
> {
>    public Response toResponse(NotFoundException exception)
>    {
>       return Response.status(Response.Status.NOT_FOUND)
>               .entity(exception.getMessage())
>               .type("text/plain").build();
>    }
> }
> This is the error message it's returning:
> WARNING: No resource methods have been found for resource class com.restfully.shop.services.NotFoundExceptionMapper
> I'm not sure why an exception mapper needs to have resource methods, or what a "resource method" is for that matter.  I think this error is appropriate for root resources only and not exception mappers, if so, this message should be suppressed for exception mappers.  OTOH, if this warning does have meaning for exception mappers, could it be made clearer for newbies/novices?
> Note this example has other bugs with it, not related to this problem (https://issues.jboss.org/browse/RESTEASY-495).
> To duplicate, download and extract RESTEasy and make the pom.xml and web.xml changes all described in https://issues.apache.org/jira/browse/CXF-3247.  Then just run mvn clean install and you'll see the above error message.
