Thanks James! I have read your reply that i think it will work. but if i have more than 3 brokers in use, it will become more and more complex. i find a artical says that activemq can provider such function. The url is here: http://incubator.apache.org/activemq/How+do+distributed+queues+work here I quoted from this artical:
"Each node communicates with a broker and we can support networks of brokers. Thats to say brokers can communicate with brokers so that we can make large networks of nodes and brokers. When a JMS producer sends a message to a JMS consumer, it may travel through several brokers to reach its final destination." but I doesn't find any examples to help me to understand how to work with it. so it is appreciate that if you could show me some examples for it.
