[jboss-as7-dev] ConfigAdmin service in AS7

[Thomas Diesler]

Folks,

I completed the configuration admin service in AS

https://github.com/jbosgi/jboss-as/commit/237c53c665df53e5931d2ef6fc15ad7584707b0b

Any service/deployment can now add its configuration properties to the 
model via the ConfigAdminService

<subsystem xmlns="urn:jboss:domain:configadmin:1.0" >
<configuration 
pid="org.apache.felix.webconsole.internal.servlet.OsgiManager">
<property name="manager.root">jboss-osgi</property>
</configuration>
</subsystem>

There are demo test cases that show how to use the service. The notion 
of ConfigurationListener is also supported, so service Foo can react to 
configuration changes for service Bar.

The ConfigAdminService is also the persistent data backend for the 
standard OSGi ConfigurationAdmin 
(http://www.osgi.org/javadoc/r4v42/org/osgi/service/cm/ConfigurationAdmin.html) 
service. The way this currently works is that we deploy the Apache Felix 
Config Admin bundle that takes care of configuration aspects for any 
OSGi bundle deployed to AS7. The Felix CM bundle delegates data 
persistence to the to ConfigAdmin subsystemn - so it shows up in 
domain/standalone.xml.

As a side effect you can use the OSGi webconsole to manage the 
configuration for any AS service that uses the ConfigAdminService.

The branch is currently waiting to get rebased onto 'bootstrap' when 
that becomes generally available.

cheers
