There are several excellent example apps on sourceforge, as well as on the links page of the basic struts documentation at struts.jakarta.apache.org > > I have a welcome file named "index.jsp".

Redirect maybe... post maybe... but not forward. Contemplate the definition of forward for wisdom.

Back, next and reload will do to a struts app what they do with any other app: Allow the user to break your application in new and interesting ways. --Jim Barrows --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
