# External ActiveMQ Broker

    <openejb>
        <Resource id="MyJmsResourceAdapter" type="ActiveMQResourceAdapter">
            # Do not start the embedded ActiveMQ broker
            BrokerXmlConfig
            ServerUrl tcp://someHostName:61616
        </Resource>

        <Container id="MyJmsMdbContainer" ctype="MESSAGE">

The {{ServerUrl}} would be changed to point to the host and port of the
ActiveMQ process.  The various URL formats that ActiveMQ supports also
work, such as 'failover:'.

The same can be done via properties in an embedded configuration, via the
{{conf/system.properties}} file or on the command line via {{-D}} flags.


    Properties p = new Properties();
    p.put(Context.INITIAL_CONTEXT_FACTORY, LocalInitialContextFactory.class.getName());

    p.put("MyJmsResourceAdapter", "new://Resource?type=ActiveMQResourceAdapter");
    p.put("MyJmsResourceAdapter.ServerUrl", "tcp://someHostName:61616");
    // Do not start the ActiveMQ broker
    p.put("MyJmsResourceAdapter.BrokerXmlConfig", "");

    p.put("MyJmsConnectionFactory", "new://Resource?type=javax.jms.ConnectionFactory");
    p.put("MyJmsConnectionFactory.ResourceAdapter", "MyJmsResourceAdapter");

    p.put("MyJmsMdbContainer", "new://Container?type=MESSAGE");
    p.put("MyJmsMdbContainer.ResourceAdapter", "MyJmsResourceAdapter");

    p.put("FooQueue", "new://Resource?type=javax.jms.Queue");
    p.put("BarTopic", "new://Resource?type=javax.jms.Topic");

    InitialContext context = new InitialContext(p);

From anywhere in the same VM as the EJB Container you could lookup the
above resources like so:
    
    javax.jms.ConnectionFactory cf = (ConnectionFactory)
            context.lookup("openejb:Resource/MyJmsConnectionFactory");

    javax.jms.Queue queue = (Queue) context.lookup("openejb:Resource/FooQueue");
    javax.jms.Topic topic = (Topic) context.lookup("openejb:Resource/BarTopic");
