In this lab you are going to implement basic login and logout operations using the Servlet Session Tracking API.

Create a Java class User that represents a user. In particular, the User class should have at least three properties: name, username, and password. You may add additional properties like id if you want.

Create a servlet Login as follows:

$($a$,$ In the init$()$ method of the Login servlet, create at least two User objects. One of the User objects must have the following property values:

name: "John Doe"

username: "jdoe"

password: "abcd"

Add the User objects to a list and save the list in application scope.

$($b$)$ In doGet$(),$ display a login form, e$.$g$.$

Username:

Password:

The form should submit data to the Login servlet using a POST request.

$($c$)$ In doPost$(),$ check if the submitted username and password match any user in the list of users. If a match is found $($i$.$e$.$ login is successful$),$ set a session attribute user whose value is the User object that matches the

submithed username and password, then redirect to the Members servlet. If no match is found $($i$.$e$.$ login fails$),$ redirect back to the login form.

Create a servlet members. This servlet first checks if the session attribute user is set. If so$,$ it displays the following:

Hi$,==$
