RE: Need Help: Please do help me

[David Cypers <da...@skynet.be>]

for page validation, i use the filter-mechanism from the servlet 2.3 api.
just write a filter which checks the parameters in your request, validates
them against an internal table , and forwards the filter chain to 1) the
page OR 2) an error page indicating that the user is not validated for the
request

if you attach your filter to the Struts controller , all requests can be
filtered (ic. validated) before the requests even reach the controller.

Regards,
David

ps : it's also very very easy to reuse your validation mechanism for other
servlets!!

For user authentication, use container security not Struts. Struts
example should not be based on login.
