Instead of writing a JSP you could register a Servlet service with a servlet object implementing the OptingServlet interface. Upon the accepts method call you might decide whether to handle the error condition or not. Thus if the servlet decides to handle, it is called. If the servlet decides not handle the condition, another servlet is looked up. Hope this helps. Regards Felix
