Pass data from Java Servlet to JSP? [duplicate]

Answer 1

import javax.servlet.http.*;

public class AccountsServlet extends HttpServlet {

    public void doGet (HttpServletRequest request, HttpServletResponse response) {

        try {
            // Set the attribute and Forward to hello.jsp
            request.setAttribute ("somename", "someValue"); // to save your temporary calculations. 
            getServletConfig().getServletContext().getRequestDispatcher("/namedcounter.jsp?name=" + req.getParameter("name")).forward(request, response);
        } catch (Exception ex) {
            ex.printStackTrace ();
        }
    }

}

In the above code servlet will not create 2 different requests. It will forward, also will retain all data from original request.

request.setAttribute ("somename", "someValue"); // to save your temporary calculations.
