Well, I will descript the problem exactly. the first page use a tag class to
render a random question from database, and their possible answers, the user
must choose the right answer and submit the form for processing.
I need the random question numbers, which are question ids to
*Results*servlet.
*Results* servlet is a servlet that must display the same questions that was
displayed in the Questions page to run a query against the database to
display the questions and the correct and wrong answers.
My Problem is that, I want to pass these numbers, Questions IDs, from the
first page, which i have made it as a tag class, to Results page, which was
made as servlet. I tried to use request.setAttribute("Ids", ids); but when
retrieve it in Results servlet, I got *null. *
That was my problem my buddy, by the way, when i used session, it worked
fine. and you stated that this will not work, but i think that storing these
ids in a session is a good choice, isn't it?
If you have any comments please post it.
