Here's the top of my activemq.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:amq="http://activemq.apache.org/schema/core"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
             http://www.springframework.org/schema/beans/spring-beans.xsd
             http://activemq.apache.org/schema/core
             http://activemq.apache.org/schema/core/activemq-core.xsd">


<bean 
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>file:${activemq.base}/conf/messaging.conf</value>
<value>file:${activemq.base}/conf/credentials.properties</value>
</list>
</property>
</bean>

As you can see, i'm using Spring, in our case because we're driving 
Camel routing configurations via imported xml files, too.

Here's a an example of using property placeholders from further down the 
file, standard Spring:

<managementContext>
<managementContext createConnector="true" 
connectorPort="${remote_jmxConnectorPort}"/>
</managementContext>

and another:

<transportConnectors>
<!-- by convention we use 51616 and 51617 (for ssl) so as not to 
conflict with Geronimo's embedded ActiveMQ defaults (61616 & 61617) -->
<transportConnector name="openwire" 
uri="tcp://0.0.0.0:${remote_openwirePortNumber}?keepAlive=true&amp;soTimeout=30000"/>
<transportConnector name="ssl" uri="ssl://0.0.0.0:${remote_sslPortNumber}"/>
</transportConnectors>

i hope this helps,
Joe
