is it possible to use environment-variables in launcher-ini? [message #1690134]

Instead of
-data
@user.home/myapp
-configuration
@user.home/myapp/configuration

I'd like to use something like this on windows-machines
-data
%APPDATA%/myapp
-configuration
%APPDATA%/myapp/configuration

I known that I could create shortcuts but:
1. I don't want to create a shortcut for each user
2. this does not work with webstart Smile

Does anybody have an idea how to use environment variables in the launcher-ini?

Thanks

Al

If this is for an app you're creating, you should consider using per-platform p2 touchpoints to configure the osgi.instance.area and osgi.configuration.area. You can see an example in the Arduino Designer.

We're building oir application for different platforms and deploy them together with our application server on customer systems.

Therefore I need a solution that works on customer side.
Best option would be to use environment variables to configure the directories.

I've tried to configire the mentioned properties in config.ini - this works for local clients but unfortunately not with webstart. Sad

I noticed a thread elsewhere in the forum that JNLP requires all properties to be prefixed with "jnlp."; that thread shows an approach for wrapping the Equinox Launcher's main() to populate the properties etc.

We already have a wrapper for the same case.
But I want a solution the works with the default and webstart launcher.

I had a look at the org.eclipse.equinox.launcher_*.jar - this file contains all launcher classes - I think this is a perfect point to patch all launchers. Smile

Do you have any idea where I can checkout the sources of this jar?
