I don't know about the "Whitebox" (whatever that is) OS, but on my
Sparc Solaris boxes, anything placed in $JAVA_HOME/jre/lib/ext/ is
automatically added to CLASSPATH when a Java app is started-up.

I decided to build on how Java works on my Sun boxes, by mimicking its
"default CLASSPATH add-ons" directory in /usr/local. Then I wrote a
"java_profile" script that automatically adds any jarfile it finds
there into the CLASSPATH environment variable. It gets run by, say,
/etc/profile, so all users get it.
