10.2.6. Enterprise Beans Security Annotations

download PDF
Enterprise beans use Annotations to pass information to the deployer about security and other aspects of the application. The deployer can set up the appropriate enterprise bean security policy for the application if specified in annotations, or the deployment descriptor.
Any method values explicitly specified in the deployment descriptor override annotation values. If a method value is not specified in the deployment descriptor, those values set using annotations are used. The overriding granularity is on a per-method basis
Those annotations that address security and can be used in an enterprise beans include the following:
@DeclareRoles
Declares each security role declared in the code. For information about configuring roles, refer to the Java EE 6 Tutorial Specifying Authorized Users by Declaring Security Roles.
@RolesAllowed, @PermitAll, and @DenyAll
Specifies method permissions for annotations. For information about configuring annotation method permissions, refer to the Java EE 6 Tutorial Specifying Authorized Users by Declaring Security Roles.
@RunAs
Configures the propagated security identity of a component. For information about configuring propagated security identities using annotations, refer to the Java EE 6 Tutorial Propagating a Security Identity (Run-As).
