Hi, we would like to implement a system with X devices. Each device has a 'broadcast topic'. Messages posted on that topic should be received by the device it was originally sent to plus the other (X-1) devices in a reliable way: messages should not get lost in case of system shutdown or network problems. When a device that went down is up again it should be notified of the messages it missed in the meantime.
We looked at several solutions but bumped into problems with each one of them. As we use JRE 1.4 and are not yet switched to JRE 5 we are forced to use Apache MQ version 4.1. If really necessary we could switch to version 5.0 but if it's not necessary we would prefer to avoid that! A. We investigated a network of brokers First we ran into the problem that the brokers did not reconnect after shutting down. This problem was fixed in AMQ-961. We tested the patch for version 4.1 and it seemed to work well. Afterwards we ran into a persistence issue (AMQ-527). That seemed to be fixed in version 5.0 which we can't use at the moment. B. We investigated fanout transport That did not work in version 4.1: specifying more than 2 brokers (fanout:(static:(tcp://remote_device1,tcp://remote_device3))) gives problems. Again, this problem is fixed in the 5.0 version we can't use. C. We investigated durable subsciptions Using durable subscriptions worked in version 5.0 but the sockets between the brokers kept closing; we found a similar bug report AMQ-1433. Switching to version 4.1 was no option because there we bumped into AMQ-319: when device A starts the initial connection to B and C blocks until B and C are up. This is different behaviour then when using version 5.0: in that version the application continues and doesn't wait for the remote connections to come up. I found bug report AMQ-319 but that doesn't solve my problem. So at the momenent we are really stuck. Does anyone have a suggestion? Could we use another solution or are we missing something? Thanks in advance!
