Is there a way to send parameters from servlet to jsp without redirecting the browser to that page?
RequestDispatcher disp = request.getRequestDispatcher("shoppingCart.jsp"); disp.forward(request, response); 
- 1put the value in session scope and get that value in any jsp pageAbhishek Mishra– Abhishek Mishra2014-06-30 17:40:12 +00:00Commented Jun 30, 2014 at 17:40
- 2u just did it. set attribute to request before disp.forward(req,res). Access it from request(within the JSP you are forwarding to) using req.getAttribute(..); FYI request dispatcher doesn't sends response to web browser(watch your url when you do dispatch, it dosn't changes); hence no redirect ..

There can be one way as below:
RequestDispatcher disp = request.getRequestDispatcher("shoppingCart.jsp"+"?myParam=myValue"); disp.forward(request, response); If you are fine with "GET" method then you can solve this problem with appended parameters.

Worth mentioning you would want to url encode the parameters if you have any special characters :)
Well you can either set the attributes(used in case of internal communication with servlets or servlet to jsp or vice-versa) to the response object and forward the request you can achieve this as :
request.setAttribute("someKey","someValue"); You can also use the session scope to share the attributes between servlet and jsp like this:
Http session = request.getSession(); session.setAttribute("someKey","someValue");
