hi!
I'm not sure what effect you like to achieve... but if the JSP
acts as view for the servlet that processes the data,
your best bet is to forward the request instead of redirecting:
(req, res are the HttpServletRequest/Response-references originally passed
to the servlet)
req.setAttribute ("name", yourresult);
RequestDispatcher rd =
getServletContext().getRequestDispatcher("path/to/your.jsp");
rd.forward(req,res);
you may add any object reference to the request with the
'setAttribut("name",objref)' method.
wrap your result inside an object and inside the jsp use
'getAtrribute("name")' to fetch the
reference to that object and thus your data.
hope this helps.
greets
btw, there is an "include"-method as well in the RequestDispatcher-class
which includes
the resource in the response and returns control back to the caller.
