I did it using a ExceptionMapper:
 
package com.perfectprintpattern.service.exception.handling;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;
import com.perfectprintpattern.service.exception.customError.CustomErrorException;
@Provider
public class CustomExceptionMapper implements
    ExceptionMapper<CustomErrorException> {
  @Context
  protected HttpServletRequest request;
  public Response toResponse(CustomErrorException exception) {
    this.request.setAttribute("javax.servlet.jsp.jspException", exception);
    return Response.status(exception.getStatus()).build();
  }
}
 
works great!!!

Betreff:[Jersey] could not be mapped to a response, re-throwing to the HTTP container
 
Hi,
 
when I fire a MyException extending RuntimeException it properly gets mapped to the JSP I defined for MyException via error-page in the web.xml.
 
This Exception gets handled properly! Why do I see the error in the subject in the eclipse IDE???
 
It's not wrong that it is mapped that way?
