For ActiveMQ 3.x/4.xTo use pure in-memory messaging you just need to set the broker URL to be vm://localhost
Actually you can use any text after vm:// so that you can segment multiple logical JMS brokers within the same JVM and classloader, using the name to distinguish between them. There is an example of how to do this along with a description of the available protocols in the Protocols overview. Also see: how to optimise the VM transport |
