hi,
I have a jsp page in which users listen to audio files and provide feedback.
Multiple files are presented on the same page; users respond to each one
individually, ie, for each response there is a form. Each time a user
presses a button, a servlet processes the data and regenerates the page so
the user can continue. My users like this better than a standard form
approach where all questions must be answered and a single form with
multiple data is submitted in a batch.
The problem is that I want to access within the jsp page a list of which
audio files have been responded to, so this can be indicated to users. I was
hoping to keep a vector of filenames in a bean and access it from the page
each time it was displayed, and add filenames to the vector from my servlet
each time users made a response. However, each time my jsp page is
regenerated by the servlet using:
RequestDispatcher rd =
this.getServletContext().getRequestDispatcher("pageneme.jsp");
rd .forward(request,response);
a new instantiation of my bean is created and I can never properly build
this vector. How can I create a persistent object that multiple
instantiations of my page can access during a given session? Do I have to
store it in a httpsession object?
thanks in advance,
Matt
