Use this task to configure resource security and security permissions for Enterprise JavaBeans (EJB) Version 2.1 message-driven beans.
The association between connection factories, destinations, and message-driven beans is provided by listener ports. A listener port allows a deployed message-driven bean associated with the port to retrieve messages from the associated destination. You create listener ports by specifying their administrative name, the connection factory JNDI name, and the destination name (other optional properties are also configurable). Listener ports provide simplified administration of the associations between connection factories, destinations and message-driven beans, and are managed by a listener manager. The listener manager is provided by the message listener service to control and monitor the JMS listeners that are monitoring JMS destinations on behalf of deployed message-driven beans. For more information about listener ports, see Message-driven beans - listener port components
Messages handled by message-driven beans have no client credentials associated with them. The messages are anonymous.
To call secure enterprise beans from a message-driven bean, the message-driven bean needs to be configured with a RunAs Identity deployment descriptor. Security depends on the role specified by the RunAs Identity for the message-driven bean as an EJB component.
For more information about EJB security, see EJB component security. For more information about configuring security for your application, see Assembling secured applications.
Connections used by message-driven beans can benefit from the added security of using J2C container-managed authentication. To enable the use of J2C container authentication aliases and mapping, define an authentication alias on the J2C activation specification that the message-driven bean is configured with. If defined, the message-driven bean uses the authentication alias for its JMSConnection security credentials instead of any application-managed alias.
To set the authentication alias, you can use the administrative console to complete the following steps. This task description assumes that you have already created an activation specification. If you want to create a new activation specification, see the related tasks.
