Hi David, yep you're absolutely right, I've been on the wrong track somehow ... So yes, one shouldn't take my statement literally.
At the end we agree on, that it doesn't make a difference for the user of Karaf if the wiring of Karaf Services is done this way or that way ;) regards, Achim 2014-03-04 21:09 GMT+01:00 David Jencks <[email protected]>: > Your view of DS does not match reality, unless perhaps you are being > entirely metaphorical in your description of how DS works.
