Hi everybody,

I have servlet (LoginHandler) which I use for several servlets to check if special logins have already taken place. My forward procedure is always something like this:




My problem is, that I want to access the attribute from the new servlet Register. How is this possible? I know I can forward the Information as an parameter, but I would prefer attributes. Any ideas how to solve this?

Best regards

Joe

Because the redirect will result in the browser generating a new request, the one to which you are attaching the attribute goes out of scope as soon as the response is sent to the client.

You'll either need to use a parameter, or to attach the attribute to a higher-scoped context (session or application), whichever makes the most sense for your app.

Another alternative is to use a forward rather than a redirect, which will not result in a new request. Whether that makes sense or not in your app, you'll need to determine.
