Re: [equinox-dev] ConfigAdmin getConfiguration from external storage

Hi Philip,

The normal way to hook config admin into an external data storage is
to write a management agent that *calls* getConfiguration() and
supplies the data via an update to the Configuration object. That way
your agent can work with any config admin implementation.

Typically config admin implementations use their own internal storage
area for persistence. If you want to customise that internal storage
then you may need to write your own implementation (though I think at
least the Felix implementation has an extension mechanism so you don't
have to write the whole thing).
