There are JUnit tests throughout the code base that demonstrate how to do this. Here's some info on some ways to embed a broker: http://activemq.apache.org/how-do-i-embed-a-broker-inside-a-connection.html > I apologize if I'm missing the examples somewhere on the site, all I'm > seeing is various ways to start/stop brokers, producers and consumers from > the command line. > > *tentatively; a master/slave w/ KahaDB might be preferable if it was stable Master/slave can be configured either using an activemq.xml and a BrokerFactoryBean or it can be configured completely programmatically using Java code. You'd just need to instantiate and configure the correct Java classes for the persistence of your choice.
