Defining Actions in the actions.xml
File 
Use
You have now included permission checks in your application to check if a user has the authorization to view reservations or to maintain a reservation for a specific vehicle type. To perform these activities, the user must have the appropriate permissions assigned in his or her user account.
To make the administration of these permission assignments easier, you will group individual permissions together in actions that the administrator will assign to the user’s roles. To specify these groups of permissions in corresponding actions, you will create a file with the name actions.xml that you will later deploy to the AS Java.
The actions.xml file that you create for this tutorial will contain the following actions:
· ViewReservations
Users that are assigned to roles containing this action will be able to view reservations.
· MaintainStandard
Users assigned to roles containing this action will be able to maintain standard vehicle types (economy, compact, intermediate, full size, and mini van).
● MaintainPremium
Users assigned to roles containing this action will be able to maintain the premium and luxury vehicle types.
The corresponding permissions are checked in the EJB methods using the QuickReservationEjbPermission class.
To create this file in the EJB project, you will use the Navigator in the SAP NetWeaver Developer Studio.
