How would you forward the user to the login page? The processPreprocess() method returns true or false.

While you can use a filter to do this, why not extend the RequestProcessor class? By overriding the processPreprocess function you can check for your flag. If found simply return true to continue processing. Otherwise forward the user onto the login page. * *James Adams wrote: >I have created an Action class which does session >validation by checking to see if a "loggedIn" flag is >set in the session - if it is absent, or set to false, >then I want to forward to the login page.
