Configure ActiveMQ broker using broker-uri

[Genc , Ömer]

Hey,

I would like to configure NetworkConnectors for the DefaultActiveMQBroker using 
a broker URI like described here:

http://activemq.apache.org/broker-uri.html

Therefore I have added the following inside my deployment descriptor for the 
the ActiveMQ Resource Adapter:

<conn:config-property-setting 
name="ServerUrl">vm:broker:(tcp://localhost:61616,network:static://(tcp://remoteHost-1:61616,tcp://
 
remoteHost-2:61616))/DefaultActiveMQBroker?broker.create=yes&amp;jms.watchTopicAdvisories=false&amp;jms.copyMessageOnSend=false&amp;jms.persistent=false</conn:config-property-setting>

However the configuration using the broker uri does not seem to work, by 
stepping through the code, I can see that no NetworkConnectors are added to the 
DefaultActiveMQBroker.

When I try to add NetworkConnectors using the file 
$GERONIMO_HOME\repository\org\apache\geronimo\configs\activemq-broker-blueprint\3.0.1\activemq-broker-blueprint-3.0.1.car\OSGI-INF\blueprint\activemq.xml
 everything works as expected.

Anyone an idea, why this does not work?
Are the configuration possibilities inside deployment descriptor somehow 
limited?

Thanks in advance,
Ömer
