Activation configuration properties are needed to configure message-driven beans at release 1.4 of the J2EE platform if the JMS API is integrated using a J2EE Connector Architecture resource adapter. This section describes the properties you may specify for message-driven beans that consume JMS messages.

You may specify these properties either in the enterprise bean deployment descriptor or in the runtime deployment descriptor, or both. Any properties specified in the runtime deployment descriptor override the properties specified in the enterprise bean deployment descriptor.
