With this setup, members of the
local
group can manage files and pro-
grams in
/usr/local
and below as they wish. They have full power over the
files and they need nothing but their own login credentials to do it. The
root
password can remain private.

This pattern can be repeated. We can give ownership of different branches un-
der
/usr/local
to other groups to allow control to be doled out in small sets.

Using a platform-neutral system like Java has both advantages and disadvan-
tages. A disadvantage is that, generally, Java products don't use the traditional
installation mechanisms of your native platform. You don't install an RPM or
a DEB. But this is somewhat offset by the fact that all a Java application needs
is for its classes to be arranged in a particular pattern on the filesystem. In other
words, all you need to do to install JBoss is to unpack the tarball.
You did the hard part already. Since you have created the group and made
yourself a member of that group,

any member of the group can install the
product:
$ cd /usr/local
$ tar xzvf jboss-3.2.3.tgz
jboss-3.2.3/lib/
jboss-3.2.3/client/
jboss-3.2.3/docs/
jboss-3.2.3/docs/dtd/
jboss-3.2.3/docs/dtd/html-svg/
...
...
etc.

take advantage of a newly created group. There are other obscure ways, such as running a sub-
shell with the
login
argument or running
su -
, but the simplest is to log out and log back in.
