Splitting activemq broker configuration into multiple files

I have an activemq broker and I want to split its configuration into multiple files. I want to prepare a separate configuration file, which will be generated automatically and which will contain only definitions of queues.

File 1: activemq.xml

<beans ...>
  <broker ...>

  </broker>
</beans>

File 2: queues.xml

<beans ...>
  <broker ...>
    <destinations>
      <queue physicalName="q1"/>
    </destinations>
  </broker>
</beans>

I tried to use:

Spring import:

<import resource="queues.xml"/>

but got

ERROR: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.activemq.xbean.XBeanBrokerService#1' defined in class path resource [queues.xml]: Invocation of init method failed; nested exception is javax.management.InstanceAlreadyExistsException: org.apache.activemq:type=Broker,brokerName=localhost org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.activemq.xbean.XBeanBrokerService#1' defined in class path resource [queues.xml]: Invocation of init method failed; nested exception is javax.management.InstanceAlreadyExistsException: org.apache.activemq:type=Broker,brokerName=localhost

XInclude:

activemq.xml:

<beans ...
  xmlns:xi="http://www.w3.org/2001/XInclude"
>
  <broker ...>
    <xi:include href="queues.xml" parse="xml"/>
  </broker>

</beans>

but got

ERROR: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 142 in XML > document from class path resource [activemq.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 142; columnNumber: 45; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'xi:include'. org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 142 in XML document from class path resource [activemq.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 142; columnNumber: 45; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'xi:include'.

Xml entities activemq.xml

<!DOCTYPE beans [
<!ENTITY queues SYSTEM "queues.xml">
]>
<beans ...>
  <broker ...>
    &queues;
  </broker>
</beans>

but got

ERROR: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 28 in XML document from class path resource [activemq.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 28; columnNumber: 3; Element type "beans" must be declared. org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 28 in XML document from class path resource [activemq.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 28; columnNumber: 3; Element type "beans" must be declared.

Any ideas? Thanks in advance.

Solution

  • I asked at activemq forums and someone posted a solution there. Here is an answer solution at activemq forum. You can use XML entities, but you have to disable XML validation, so you have to start with: bin/activemq start 'xbean:conf/activemq.xml?validate=false'
