Many of the web-based applications consists of login module which lets the user enter with its own identity and also let the admin authenticate the user or differentiate between the registered and normal user. So every user should have identification strings like user id and password. This section explains how to develop this application in JSF.
This application displays a web page indicating the user to enter login id and password in the appropriate fields. If user enters correct information then a message indicating successful login is displayed otherwise failing message is
displayed. For this application login id and password are given below:
Login ID: JavaJazzUp
Password : mypwd
