Thanks for all your hard work! I have a query regarding 'sending a message to the back of the queue'. I am processing messages in a cluster and sometimes a message is received but the rest of the cluster hasn't finished doing what it needs to, so that message needs to get sent to the back of the queue. Currently, I do this by just queueing up a new message. The problem is, if the queue is empty, one node in the cluster will immediately pick up that message again (even though the other nodes are still processing). I want to delay this. I tried using JMS_JBOSS_SCHEDULED_DELIVERY and that +almost+ works, but if the queue is +not+ empty this appears to let the new message (which I have put to the end of the queue) jump the queue in accordance with the 'scheduled delivery time'. What I need is like a JMS_JBOSS_DO_NOT_DELIVER_BEFORE. So if the queue is empty it will wait, but if the queue was full and it took a long time to get to the message anyway it will be processed as normal. Can I implement this somehow? Thanks in advance, Richard. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/542981#542981] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
