Hi, I am able to control my deployed MDB programatically. Basically my code invoke the responsible MBean for that MDB and call the invoker.stopDelivery() method on that MBean. It will restrict the MDB to get the message from Queue. I can also withdrow the restriction of the MDB to get message from queue by invoking invoker.startDelivery(); on the MBean. responsible MBean is Code: MBean Name: Domain Name: jboss.j2ee service: EJB plugin: invoker binding: message-driven-bean jndiName: MessageEJB MBean Java Class: org.jboss.ejb.plugins.jms.JMSContainerInvoker -------- But the problem is after invoking invoker.stopDelivery() ,still the MDB reads the 1st queue message. That is If I send 4 message after stop It will read the 1st one - other 3 messages are blocked unless I invoke startDelivery(); If I send 7 messages - MDB consume 1 st one :( other 6 are blocked . then when I invoke startDelivery(); I will get the 6 messages with MDB. Can any body help me -???
