Subject [jira] [Commented] (CONFIGURATION-498) Add OSGi Configuration Admin Service as a source for configuration data
Date Wed, 23 May 2012 19:47:41 GMT

Oliver Heger commented on CONFIGURATION-498:
--------------------------------------------

This is certainly a valid request. Unfortunately, I am pretty new to OSGi, so it is not directly
clear for me where Commons Configuration fits into the picture.

As I have read, there are multiple aspects related to the Configuration Admin service:
* You can create a ManagedService or a ManagedServiceFactory, and then Configuration Admin
calls your service when a configuration is created or changed passing in a Dictionary object.
The creation of configurations is done through methods of the Configuration Admin service.
* Bundles can specify meta data describing the configuration options they support.
* There is a preferences services which can be used by bundles to persist their settings.

Which of these services would you like to access through our Configuration interface?

with it, so please close this issue if it is naive or poorly matched to the goals of the project.

> As part of the OSGi spec, a service called "Configuration Admin" is available to provide
access to properties-based configuration that is stored in the container.  Providing access
to that facility via commons-configuration seems like an ideal situation since it can further
abstract the container that the client code is running on, now including OSGi containers such
as Karaf or Felix.
