Hi david I spent a little to much allocated time on this so I had to move on, and I am going to come back to it at a later date. I have a quick 'hack' (a taglib which checks the session in each jsp) for my prototype to present to the client......Anyway, when i do it i will let you know.....
What i have found so far though is that by using declarative exception handling in my struts-config.xml the error, i think, needs to be thrown from a action class. If i could do it from my requestProcessor that would be great? I wasnt sure how to configure my app to call processRoles() on evey request, so i overrode the locale method as a test as this was been called eveytime. However because the locale method dosnt throw any exceptions i again ran into problems. So overall what i really would like to do would be to extend requestProcessor with my own custom method which throws my own exception which will be redirected to the appropriate page and called on every request. Sounds easy and probably is to someone who has a better understanding of stuts than i do? Anyway wont give up and will let you know if you are interested....? Bank holiday this monday!! so a long relaxing weekend is due before i crack on with this one ; ) cheers Andy On Friday 22 Aug 2003 4:21 pm, you wrote: > Andy, > > Did you get processRoles to work for you? > How do you redirect to the (error) page of > your choice in it? > > Thanks, > David > > -----Original Message----- > From: Andy Richards [mailto:[EMAIL PROTECTED] > Sent: Thursday, August 21, 2003 9:55 AM > To: Struts Users Mailing List > Subject: Re: login request + ActionServlet RequestProcessor Action > > > Hmm > > Strugling a bit with this one now.??
