Practical 1B: Create a servlet for a login page. If the username and password are correct then it says message “Hello ” else a message “login failed”


index.html

<html>
<head>
<title>Login Form</title>
</head>

<form action="LoginServlet" >

Enter User ID<input type="text" name="txtId"><br>

Enter Password<input type="password" name="txtPass"><br>

<input type="reset">
<input type="submit" value=" Click to Login " >
</form>
</html>


LoginServlet.java

package mypack;

import java.io.*;

import javax.servlet.ServletException;

import javax.servlet.http.*;

public class LoginServlet extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8);
PrintWriter out = response.getWriter();
out.println("<html><head><title>Servlet LoginServlet</title></head>");
 String uname = request.getParameter("txtId");

String upass = request.getParameter("txtPass");

if(uname.equals("admin") && upass.equals("12345"))
{
out.println("<body bgcolor=blue >"); 
out.println("<h1> Welcome !!! "+uname+"</h1>"); 
}
else{
out.println("<body bgcolor=red >");
out.println("<h1> Login Fail !!! </h1>");
} 
 out.println("</body></html>");

}

}
