Felix, That is sort of the way I am currently setting my system property, and it is the only option I see so far.
Bengt, Yes, I agree with your statement about system properties overriding environment properties. But it would be nice to be able to have file install access the environment variables. Ultimately, I am trying to have multiple karaf instances watch the same directory for configuration file changes. This has been accomplished, but it would be a lot cleaner if the file install could access environment variables. - Andrew ________________________________ From: Bengt Rodehav <[email protected]> To: [email protected] Sent: Monday, December 10, 2012 7:28 AM Subject: Re: File Install System Properties I guess the System.getEnv() method could be used to give FileInstall access to the environment variables. I've been thinking about this myself. Right now I have to fill my startup scripts (and wrapper.conf) with "-D..." for every environment variable I want to use. File install could have an option to enable this. Logically, I think system properties should override environment properties. /Bengt 2012/12/10 Felix Meschberger <[email protected]> > Hi > > This is probably more of a generic Java question than a specific Karaf or > Felix question... > > The only way, I know if is to launch Java with things like > > java -Dsys.prop="$ENV_PROP" > > Regards > Felix > > Am 07.12.2012 um 21:21 schrieb Andrew Burks: > > > Hello Felix, > > > > Thanks for the response.
