this is correct. but problem is there are different messages in different servlets which should display in the login.jsp page. for this scenario how to do that?

mali_angel 9-Jul-13 2:35am View

this is too complex for a beginner like me :(

mali_angel 9-Jul-13 2:34am View

Your both answers did not work for me. both displays 'null' before login. once user logged it displays correct message. i want to stop displaying 'null' word before display correct message.

mali_angel 9-Jul-13 2:00am View

why URLEncoder.encode(message)); line's encode word cut by a line?

mali_angel 9-Jul-13 1:46am View

message srings are in servlets.I want to do those messages show in jsp. in here out.println(""); these lines should not empty right? this line "<p><%=request.getAttribute("loginMsg") %></p>" is public for every servlet message.

I have an another issue..in my project Login.jsp page login button connects to UserServlet.java file.but I took another file to keep session codes. I want to connect Login.jsp to Usersevlet.java file loginDetail method. Inside that method I need to Call Session file loginSession method. my question is how to do that?

mali_angel 5-Jul-13 7:27am View

Do i have to do both operations? or only one?

mali_angel 5-Jul-13 3:10am View

I Created This method to check login status. is this right? are there any mistakes? how do we check this code with different users?please tell me whether its correct or not. Thank you in advance

private void loginSession(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{
HttpSession session = request.getSession(false);
try {
response.setContentType("text/html");
PrintWriter writer = response.getWriter();
writer.println("<html><body>");
// If user is not in a session then he is not logged in
if (session == null) {
session = request.getSession();
String message = "You are not logged in!";
response.setContentType("text/html");
request.setAttribute("loginMsg", message);
RequestDispatcher rd = getServletContext().getRequestDispatcher("/Login.jsp");
rd.forward(request, response);
//current user
}else if(session.isNew()==true){
response.sendRedirect(response.encodeRedirectURL("Login.jsp"));
}
else if (!session.isNew()){
String message = "Thank you, you are already logged in...Here is the data in your session";
request.setAttribute("message", message);
RequestDispatcher rd = getServletContext().getRequestDispatcher("/Menu.jsp");
rd.forward(request, response);
//new user
}else if((String)session.getAttribute("username")==null){
String message = "Time out please login!";
request.setAttribute("loginMsg", message);
RequestDispatcher rd = getServletContext().getRequestDispatcher("/Login.jsp");
rd.forward(request, response);
}
} catch (Exception e) {
e.printStackTrace();
}
}

how to do flag? is this a flag?
session.setAttribute("username", Uname);

mali_angel 4-Jul-13 7:21am View

thanx JasminHan309. im also a java learner. defenitly i ll share if i know anythng about this :)

mali_angel 4-Jul-13 5:18am View

I cannot understand how to check this code. how do I know whether it is correct or not.

next time I don't want to login again to access the functionalities? So, I need to put a flag indicating the login status in the session object which span the life cycle of a specific time, e.g, 30 minutes. And the put a filter to query the flag every time a request comes to determine if the client has logged.

How am I going to do above things? here my another file of this project..

package com.mobitel.bankdemo.web;

import java.io.PrintWriter;
import java.util.Enumeration;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
/**

*/
@WebServlet("/GetSession")
public class GetSession extends HttpServlet {
private static final long serialVersionUID = 1L;

public GetSession() {
super();
// TODO Auto-generated constructor stub
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
HttpSession session = request.getSession(false);
try {
response.setContentType("text/html");
PrintWriter writer = response.getWriter();
writer.println("<html><body>");
// If user is not in a session then he is not logged in
if (session == null) {
String message = "You are not logged in!";
request.setAttribute("loginMsg", message);
RequestDispatcher rd = getServletContext().getRequestDispatcher("/Login.jsp");
rd.forward(request, response);
//current user
} else if (!session.isNew()){
String message = "Thank you, you are already logged in...Here is the data in your session";
request.setAttribute("message", message);
RequestDispatcher rd = getServletContext().getRequestDispatcher("/Menu.jsp");
rd.forward(request, response);
//new user
} else if((String)session.getAttribute("username")==null){
String message = "Time out please login!";
request.setAttribute("loginMsg", message);
RequestDispatcher rd = getServletContext().getRequestDispatcher("/Login.jsp");
rd.forward(request, response);
}
} catch (Exception e) {
e.printStackTrace();
}
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}

}</body></html>

Is this correct or not? what are my mistakes here

Thank you in advanced
