RequestDispatcher

[Lucky Singh]

Is this right?

public class Login extends HttpServlet
{
public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException, ServletException
{
String user, pass;
boolean response = false;

user = req.getParameter("username");
pass = req.getParameter("password");

DatabaseChecker ct = (DatabaseChecker)(getServletContext().getAttribute("ct"));
response = ct.validate(user,pass);

if(response == true)
{
HttpSession userSession = req.getSession(true);
userSession.putValue("userName", user);
RequestDispatcher rd = getServletContext().getRequestDispatcher("/Welcome.jsp");
if (rd != null)
{
rd.forward(req,res);
}
}
else
{
//Return to LoginPage.
RequestDispather rd2 = getServletContext().getRequestDispatcher("/Login.jsp");
rd2.forward(req,res);
}
}//end doGet.
}//end Login.

Hi there,
I was told to put return; after the call to rd.forward(req, resp);
I also used String nextScreen to hold the "/Welcome.jsp" or "/Login.jsp" names so used the following format:

        String nextScreen = "/Welcome.jsp" ;
        if ( found ) 
        {
            RequestDispatcher rd =
                request.getRequestDispatcher( nextScreen ) ;
            rd.forward( request , response ) ;
            return ;
        }
        else 
        {
            RequestDispatcher rd =
                request.getRequestDispatcher( "/Error.jsp" ) ;
            rd.forward( request , response ) ;
            return ;
        }

Hope that helps.
All the best,
Kate!!
