Subject [jira] Commented: (AMQ-2939) plugins attribute is missing from brokers element in XSD.
Date Thu, 28 Oct 2010 09:39:00 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-2939?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=62888#action_62888

Dejan Bosanac commented on AMQ-2939:
------------------------------------

Adding some more side-effects of Spring 3 schema validation

- in activemq.xml file I define the following configuration
<managementContext>
<managementContext createConnector="true" connectorPort="${activemq.jmx.port}" />
</managementContext>

- then I add some system properties on the command line of the JVM:
Java Runtime: Sun Microsystems Inc. 1.6.0_20 /usr/lib/jvm/java-6-sun-1.6.0.20/jre
 Heap sizes: current=253440k  free=250641k  max=506816k
   JVM args: -Dorg.apache.activemq.UseDedicatedTaskRunner=true -Xms256M -Xmx512M -Dactivemq.instance=testrbr
-Dactivemq.jmx.port=1099 -Dactivemq.jetty.port=8161 -Djava.util.logging.config.file=logging.properties
-Dcom.sun.management.jmxremote -Dactivemq.classpath=/mnt/export/activemq/testrbr/conf;/usr/share/activemq/conf;
-Dactivemq.home=/usr/share/activemq -Dactivemq.base=/mnt/export/activemq/testrbr

Unfortunately this fails because of XML validation:
   Caused by: org.xml.sax.SAXParseException: cvc-datatype-valid.1.2.1: '${activemq.jmx.port}'
is not a valid value for 'integer'.

I'm still confused if I setup my own xsd with an element for the plugin, how do I tie that
to the plugin bean?
