Access to the quick car rental application is now protected with the J2EE security roles AccessQuickCarRental, CarRentalEmployee, and BookingAgent. Therefore, users must be assigned to the appropriate J2EE security roles to have access to the application and perform certain tasks.
In this step, you will assign the users you created in the last step to the corresponding J2EE security roles. The following rules apply:
· Employee and Agent are able to access the application. You will assign these users to the J2EE security role AccessQuickCarRental, which protects access to the JSP.
· Employee is able to view reservations. You will assign this user to the J2EE security role CarRentalEmployee, which protects access to the EJB methods. Users assigned to this role only have access to the methods used for displaying information.
· Agent is able to perform all actions. You will assign this user to the J2EE security role BookingAgent, which also protects access to the EJB methods. Users assigned to this role have access to all of the EJB’s methods.
· OtherUser does not have access to the application.
The J2EE Engine is running.
You are connected to the J2EE Engine as an administrator using the Visual Administrator.
