Gentoo 2004.1:
* emerge jboss. Note that the directory layout of JBoss on Gentoo differs from most other distros’ and JBoss’ official layout (you’ll thus need to adjust a couple of ant variables to make the examples work).
* There isn’t any ebuild for JOnAS yet. Install it manually or – better – write an ebuild.
SuSE 9.1 (Professional):
* There are rpm packages both for JBoss and JOnAS. Rpmseek: JBoss and JOnAS
Debian Unstable:
* apt-sources for JBoss
* There aren’t any apt-sources for JOnAS. Create your own deb of JOnAS and become a package maintainer.
