Hi Balazs,
I'll be happy to explain that.
All you need to do in order to enable the management component is to have
the management jar (neo4j-management-{VERSION}.jar) on the classpath of your
application.
The service extensions system enables the Neo4j kernel to pick these things
up automatically.
When your application is running you access the management properties with
JConsole as usual.
Cheers,
-tobias
