Using Security Expressions
For checking security in the user interface or in the Oracle ADF binding layer, Oracle ADF provides the following set of specialized security expressions: 
#{securityContext.authenticated}
#{securityContext.userName}
#{securityContext.userInRole['roleList']}
#{securityContext.userInAllRoles['roleList']}
#{securityContext.taskflowViewable['target']}
#{securityContext.regionViewable['target']}
#{securityContext.userGrantedResource['permission']}
#{securityContext.userGrantedPermission['permission']} 
To add a security expression to a user interface component, select the component in the visual page editor and open the Property Inspector. Click the down-arrow icon to the right of the property to which you want to add the expression (such as the disabled property on an af:showDetail item on a panel tab). Choose Expression Builder from the context menu that appears.
