see the posting by "Jan T. Kim" with the subject "Re: login, path and 
~/.profile" in this ML dated 09/30/05.

what i have on my system for java is that:

/usr/bin/java is a sym link to /etc/alternatives/java

/etc/alternatives/java is a symlink to /usr/lib/j2sdk1.4-sun/bin/java

if you want a different 'default' java implementation, change 
the /etc/alternatives/java symlink to point to a different executable.

but then i've always just stuck with sun's jvm. haven't really juggled 
multiple jvms.
