Hi
Try to using FileInstall and ConfigAdmin together.
I can read the config properties from ConfigAdmin,
But I have problem to write it back.
Both FileInstall .cfg file and ConfigAdmin cache .config filw won't update.
My code is like:
Configuration config =
configAdmin.getConfiguration("xxx.xxx.xxx.xxx");
props = config.getProperties();
props = new Hashtable();
props.put("xxx", "xxx");
config.update(props);
Any clue?
Thanks
