JVM = Java Virtual Machine ... although technically not correct, many
people use the term interchangably with JRE.

No, the Jmol application is a normal application that does not require the
development kit.

However, the java runtime on your system is very old ... it needs to be
updated.

You are correct, development kit is not needed.

(RedHat 7.2 was announced in Jan 2002 ... you may want to consider
installing something newer)

If you are running on Linux then it is a complicated world ...

Download the java runtime environment .rpm.bin file
su #become root
chmod +x ja*.rpm.bin
./ja*.rpm.bin

Now, given the age of 7.2, this may not work ... but I suspect that it will.
