Yes and no: Yes, FileInstall will not currently write back changes. There is an enhancement request for this (https://issues.apache.org/jira/browse/FELIX-2571). But the ConfigurationAdmin internal persistance file is certainly written back. But this is not your consumption ;-) > My code is like: > > Configuration config = > configAdmin.getConfiguration("xxx.xxx.xxx.xxx"); > props = config.getProperties(); > props = new Hashtable(); Beware: I suggest you only create a new Hashtable() if getProperties() returns null (if the configuration is new). For an existing configuration, I would rather just update the modified properties.
