Re: Settings Service PID with FileInstall
Hi Guillaume, I'm still not convinced :) Since a file name is usually unique since we are talking of the combination of FileInstall and ConfigurationAdmin.

Re: Settings Service PID with FileInstall
Fileinstall can monitor multiple directories, so you'd need the full path in order to have a unique id. And the ConfigurationAdmin API gives no way to set the PID anyway, so not sure how we could do that. The API only allow the creation of a new factory configuration given its factory PID or the modification of an existing configuration.

Re: Settings Service PID with FileInstall
Guillaume, you are right that if there are multiple directories watched you run into this issue. Never the less the ID still would be unique, just the stored data wouldn't which leads to quite a mess when looking for the reason :) Since the ConfigurationAdmin API doesn't give a way of adding this PID, ok I give up :) Just thinking about a perfect world, where we certainly don't live in, it would have helped. regards, Achim 2011/4/5 Guillaume Nodet gno...@gmail.com: Fileinstall can monitor multiple directories, so you'd need the full path in order to have a unique id.

Re: Settings Service PID with FileInstall
oops, must have missed that :) 2011/4/5 Guillaume Nodet gno...@gmail.com: Yeah, I agree. In Karaf, we've enhanced the config commands so that you can actually edit a configuration based on the zookeeper file it uses, so that should help too.

Re: Settings Service PID with FileInstall
Hi Thanks for the answer. I don't really get why there is this behavior. I get that if you don't have a PID ConfigAdmin should generate one but why not being able to specify one is kind of strange. For example with this behavior I cannot use the metatype which requires the PID be placed on the metatype.xml file Carlos On Apr 1, 2011, at 9:15 AM, Guillaume Nodet wrote: The ConfigAdmin spec specifies that the PID has to be generated, so no, that's not possible.
