This section describes the items defined in the DD of the Message-driven Beans.

With the DD of the Message-driven Beans, you set up the items listed in the following table using the attributes specified beneath the <activation-config> tag.

Table 7-10 Items specified with the attributes beneath the <activation-config> tag

Attribute	Data type	Specifiable value	Default value	Explanation
destination	String	--	--	Specifies the name of the destination that sends the message to the Message-driven Bean. Specify the name set in Name of the Administered object for the CJMSP resource adapter in this attribute.
destinationType	String	javax.jms.Queue javax.jms.Topic	--	Specifies the queue (javax.jms.Queue) or topic (javax.jms.Topic) as the destination type.
messageSelector	String	--	--	Specifies Message Selector to select the messages to be received.
subscriptionName	String	--	--	Specifies the name of the persistence subscriber. Make sure you specify this attribute when Durable is specified in the subscriptionDurability attribute.
subscriptionDurability	String	Durable NonDurable	NonDurable	Specifies whether to set the persistence subscriber. If you want to set a persistence subscriber, specify Durable, and if you do not want to set a persistence subscriber, specify NonDurable. This attribute is only valid when javax.jms.Topic is specified in the destinationType attribute. Also, make sure you specify the following attributes when you specify Durable: subscriptionName clientId
clientId	String	--	--	Specifies the identifier of the persistence subscriber for connecting to CJMSP Broker. Make sure you specify this attribute when you specify Durable in the subscriptionDurability attribute.
acknowledgeMode	String	Auto-acknowledge Dups-ok-acknowledge	Auto-acknowledge	Specifies the acknowledgement mode. For details on the modes to be specified, see the JMS specifications.
endpointExceptionRedeliveryAttempts	Integer	1 to 2147483647	6	Specifies the number of re-delivery attempts if an exception occurs during message delivery.
sendUndeliverableMsgsToDMQ	Boolean	true false	true	Specifies whether to register the un-delivered messages in the dead message queue when a Message-driven Bean throws a runtime exception and when the re-delivery attempts exceed the count specified in the endpointExceptionRedeliveryAttempts attribute. If you want to register the un-delivered messages in the dead message queue, specify true, and if you do not want to register the un-delivered messages in the dead message queue, specify false. If you specify false, the applicable messages are re-delivered to the valid consumers by CJMSP Broker (might even be delivered to the same Message-driven Bean again).
endpointPoolMaxSize	Integer	1 to 2147483647	1	Specifies the maximum endpoint pool value.
endpointPoolSteadySize	Integer	0 to 2147483647	1	Specifies the minimum endpoint pool value.
endpointExceptionRedeliveryInterval	Integer	1 to 2147483647	500	Specifies the interval for re-delivering a message to the endpoint, when an exception occurs, in milliseconds.
