Re: [equinox-dev] About CM

["jerry lin" <bluedavy@xxxxxxxxx>]

I'm so sorry for my poor knowledge about the CM implemention of Equinox.

In equinox,We can set service's "service.bundleLocation" value to
null,then we can use ConfigurationAdmin to manage other bundle's
service properties without service's bundleLocation.
Code like this:
<component name="PortComponent">
	<implementation class="com.terdon.spike.port.PortService"/>
	<property name="service.pid" value="com.terdon.port"/>
	<property name="service.bundleLocation" value="null"/>
	<service>
		<provide interface="org.osgi.service.cm.ManagedService"/>
	</service>
</component>
then ManageBundle can use this to manage the configuration:
Configuration configuration=admin.getConfiguration("com.terdon.port", null);

But about how to share properties in two & more bundles,I don't know.
can somebody tell me how to do?
