Update the map on change .cfg file on Karaf
Hi,
I have defined map based on values from my .cfg file on Karaf. In java code
I use ConfigurationAdmin and Configuration to fill the map. I would like to
update my map when .cfg file was modified but without restaring bundle. Is
it possible to do?
Thank you for any advice,
Dominik Marciniszyn

You may find using a DS component with required configuration and configuration via an annotation considerably simpler.

Thank you, I've used this method and it works good for one file. But I saw If
I would like to handle multiple .cfg files there is a problem. I found an
example of using updated callback function. To do this I need to first
register service and then I can use this method. But in case of many files I
cannot do this. Is there other way to achieve this?

The standard way to obtain the configuration is to registered a
ManagedService object in the OSGi registry.
ConfigAdmin will call it when published, and whenever the configuration is
changed. You don't have to restart your bundle.
