Unable to bind to a port on Openshift

问题

I am running an embedded activemq message server in my application on openshift. According to this, you can only bind on 15000 - 35530. I've tried doing the following, but it's throwing a serious error. What could be the issue?

I am using spring. This is a part in my applicationContext.xml

<amq:broker brokerName="tentacle-broker" start="true">
    <amq:persistenceAdapter>
        <amq:amqPersistenceAdapter directory="/var/lib/openshift/username/jbossews-2.0/jbossews-2.0/activemq2" maxFileLength="32mb"/>
    </amq:persistenceAdapter>
    <amq:transportConnectors>
        <amq:transportConnector uri="tcp://127.10.180.129:15001"/>
    </amq:transportConnectors>
</amq:broker>

This is the error that i'm having

In Openshift, you may only bind to the port that the server allocates for you. Typically that is the value of the environment variable $OPENSHIFT_JBOSS_PORT (it varies between cartridges) and the value differs between gears. Binding to any other port will be reported as an SELinux policy violation and denied.
