JAVA_HOME isn't required for anything - it had an important role
under JDK1.1, but that's no longer the case. The usual convention
is that it points to the top of your SDK or JRE installation - that
is, either to /usr/java/jdk1.3<whatever> if you install an SDK, or
/usr/java/jre1.3<whatever> if you install a JRE. Although the SDK
and JRE installations don't care about that variable, there are lots
of scripts lurking about that do.

It contains development tools such as the Java compiler - which is
needed for runtime compilation of JSPs.

The SDK is a superset of the JRE. Things found only in the SDK live in
the jdk1.3/lib directory, things found in both live in the jdk1.3/jre/lib
directory.
