I created a small ExceptionMapper that I thought would catch all
exceptions thrown from my resource class.  But it doesn't catch any
exceptions.  That makes me think it's not properly registered.	How can
I tell if it's registered or not?  What is the proper way to do it.  I
can't seem to find what I'm looking for in the forums or the samples.
My ExceptionMapper starts off like this:
package com.foobar.atg.sniffernet.collector.provider;
import javax.ws.rs.core.*;
import javax.ws.rs.ext.*;
@Provider
public class JSONExceptionMapper implements ExceptionMapper<Exception>
{
    public Response toResponse(Exception e) {
-------
My web.xml has this in it:
   
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</s
ervlet-class>
     <init-param>
       <param-name>com.sun.jersey.config.property.packages</param-name>
       <param-value>com.foobar.atg.sniffernet.collector.resource;
                    com.foobar.atg.sniffernet.collector.provider
       </param-value>

The jetty server log shows this:
