Deploy 2 Platform instances on same Tomcat

I’m trying to deploy 2 versions of Platform version 1.11.5 on the same tomcat instance. I’ve given the wars different names and I’ve been able to define the application homes. Both instances start ok only that I’m getting the following activemq error:

I’ve tried setting vm://localhost?create=false in the second instance as per the advice from this post http://comments.gmane.org/gmane.comp.java.activemq.user/36774 but this does work.

Here’s what’s defined in the context.xml file on both war(s) (NB:// This had been commented out)

    <Resource
            name="jms/ConnectionFactory"
            auth="Container"
            type="org.activemq.ActiveMQConnectionFactory"
            description="JMS Connection Factory"
    factory="org.activemq.jndi.JNDIReferenceFactory"
    brokerURL="vm://localhost:61626"
    brokerName="LocalActiveMQBroker"/>

    <Resource
            name="jms/someTopic"
            auth="Container"
            type="org.activemq.message.ActiveMQTopic"
            description="my Topic"
    factory="org.activemq.jndi.JNDIReferenceFactory"
    physicalName="FOO.BAR"/>

    <Resource
            name="jms/someQueue"
            auth="Container"
            type="org.activemq.message.ActiveMQQueue"
            description="my Queue"
    factory="org.activemq.jndi.JNDIReferenceFactory"
    physicalName="FOO.BAR"/>

Any suggestions.
