[QUOTE="heenputha, post: 9822263, member: 313147"] Here is the simple login form.. This code goes with index.jsp. YOur jsp page <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>JSP Page</title> </head> <body> <h2>Hello World!</h2> <form action="Login"> <input type="text" name="name"/> <input type="password" name="pass"/> <input type="submit" value="Login"/> </form> </body> </html> This is the login.java class.
