Re: about filter

[Bob Withers]

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

SERVLET-INTEREST£¡

          when a method of a servlet is successful, its filter begin to 
do something, or the filter not do anything.
    I want to know, in filter how to know whether that method is successful?
