Currently we look for /etc/sysconfig/jboss-eap file.

That doesn't exist on all systems - especially not AS based ones where it seem to be /etc/sysconfig/jboss-as

Would it be possible to use ~/.jboss instead ?

Where ~/ is the home directory of the user used to login with ?

Then this is not bound to product or project; and it does not depend on read access to system files and you can have multiple configurations as long as you log in with different user.

Need to sync with Marek on the chosen one.
