Re: about filter

When the final filter in a chain calls doFilter() the service method of the 
servlet is called.  If the servlet throws an exception it can be caught and 
acted upon by a filter if you wish.

try
{
     doFilter(req, resp, chain);
}
catch (Exception e)
{
      // the servlet failed
}

Bob
