Subject How many ports does AMQ try to listen on?
Date Sun, 30 Oct 2011 15:33:22 GMT
I've got activeMQ failing to bind to a port which I never told it
about. I'm guessing that it calculates that number from the number I
did give it. How can I make all the port numbers explicit? The port
I'm supplying is port 49342 assigned by a utility that looks for
unused ports. So I don't see where it gets 49353.

A little code:

    brokerService.setSchedulerSupport(false);
    brokerService.setUseJmx(false);
    brokerService.setPersistenceAdapter(new MemoryPersistenceAdapter());
    brokerService.setPersistent(false);
    brokerService.setUseShutdownHook(true);
    brokerService.setUseLoggingForShutdownErrors(false);
    brokerService.setSchedulerSupport(false);
    bindAddress = "tcp://0.0.0.0:" + getBrokerPort();
    tcpTransport = brokerService.addConnector(bindAddress);
    brokerService.setDataDirectory(dataDirectory.getAbsolutePath());
    brokerService.start();

A bit of logging:
