Hello, I hope everyone is doing well today. I have a question about MDB deployment configurations. I am using Xdoclet to generate the ejb-jar.xml and jboss.xml files needed for deployment. Using XDoclet, are there any annotations or ant tasks I can use indicate the desired size of the MDB pool? For example, I want only one MDB listening on the designated queue at all times. If I cannot use XDoclet to do this, how can I edit the deployment descriptors manually to achieve this effect? I don't know if this will help, but here are the current XDoclet annotations that I am using. /** * @ejb.bean name="IntegrationConsumer" displayname="TestConsumerMDB" * acknowledge-mode="Auto-acknowledge" * destination-type="javax.jms.Queue" * subscription-durability="NonDurable" transaction-type="Container" * * @jboss.destination-jndi-name name="queue/ExpressReportsIntegrationQueue" */ public class IntegrationConsumerBean implements MessageDrivenBean, MessageListener { Thank you very much for your time and assistance.
