I'm trying to load JSP files from servlets.but this program is nort working. can anyone tell me ehat might be the problem.


import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class Login extends HttpServlet{

public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException,IOException{


String userId = req.getParameter("userId");
String password = req.getParameter("password");

String uName =userId;

// if uName is null .. user is not authorized.

if (uName == null)
{

PrintWriter ot = res.getWriter();
ot.println(" Please verify the Userid and password");
ot.close();
}
else
{

// So the user is valid let's create a seesion // for this user.

HttpSession userSession = req.getSession(true);

// put the user name session variable.

userSession.putValue("userName", uName);

// now we need to transfer the control to welcome.jsp

RequestDispatcher rd =
getServletContext().getRequestDispatcher("/welcome.jsp");

if (rd != null)
{
rd.forward(req,res);
}

}


}// end of doPost

}// end of servlet class

thanks in advance.
bye

Not exactly an Ant question is it? Moving to the Servlets forum.

What do you mean "not working"? Are you seeing errors in the browser window, in your logs?
