Hi Claus, Thanks for the link. I think I am using similar approach. My first route "calcQueue" takes incoming message and puts it on a user specific queue (e.g. activemq:queue:Order.User1, activemq:queue:Order.User2)
> <route id="calcQueue"> > <from uri="activemq:queue:WO" /> > <recipientList id="recipientList1"> > <method method="calculate" bean="queueCalculator" /> > </recipientList> > </route> "OrderProcessor" bean in second route "ProcessOrder" processes incoming messages on user specific queues (e.g. activemq:queue:Order.User1, activemq:queue:Order.User2) > <route id="ProcessOrder" errorHandlerRef="deadLetterErrorHandler"> > <from uri="activemq:queue:Order.*" /> > <bean ref="OrderProcessor" method="process" /> > </route> The issue is that when activemq:queue:Order.User1 is in retry mode, Camel doesn't process any messages from other user specific queues. I have redelivery delay of 5 minutes and it will increase in future. At present, Camel doesn't process any message for more than 30 minutes if one queue is blocking. My requirements are: 1) Messages should process in sequential order for each queue. This means that if activemq:queue:Order.User1 is in retry mode, none of the messages from activemq:queue:Order.User1 should process until redelivery attempts are exhausted. 2) When one queue is blocking in retry mode, Camel should continue to process messages in other user specific queues (e.g. activemq:queue:Order.User2, activemq:queue:Order.User3.) Do you think if I define one route per user specific queue then I can achieve above requirements? At present, I have only route defined with wild char character in it? I appreciate you help.
