Split ActiveMQ broker configuration into multiple files.

[rattaman <zb...@gmail.com>]

Hello,
I want to split configuration of the ActiveMQ Broker into two files. The
first one will contain the general configuration of the broker and the other
one will contain a list of predefined virtual destinations. We want to
generate those queues automaticaly based on some external data and so we
don't want to put it in the same file as the broker configuration.

Here is a general idea with queues instead of virtual destinations.

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

which is kind of what one could expect.

I also tried to use XInclude but my parser doesn't support this, and DTD
entity, but you can't use it together with XSD.

Any ideas? 

Best regards

I tried to use XML entities before, but failed at the validation step. Looks
like it works if you disable it.

Thank you.

Left this out:

*activemq.xml*

...
        <destinations>
            &virtualDestinations;
        </destinations>
...

The following works for me:

*activemq.xml*


*virtualDestinations.txt*


On startup of the broker, you need to add "?validate=false" to the xbean
url, like this:

    *bin/activemq start 'xbean:conf/activemq.xml?validate=false'*
