How do you know that the doFilter method isn't executing? The first thing I would try is to create a dummy JSP page in the Jsp folder that looks something like: <html> <head></head> <body> <pre> <% (new Exception()).printStackTrace(out); %> </pre> </body> </html> If your Filter shows up in the stack trace, then it is being called, and the problem is in the Filter. > Can anyone help me to figureout the problem ?

Usually you have to override all of the parameter related methods in your HttpServletRequestWrapper to make certain that they show up in the target servlet. > Manoj. > > -- > View this message in context: > http://www.nabble.com/Tomcat-6-and-Servlet-filter-problem-tp17337357p17337357.html > Sent from the Tomcat - User mailing list archive at Nabble.com. > > > --------------------------------------------------------------------- > To start a new topic, e-mail: users@tomcat.apache.org > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
