If you install just the sun rpm, they are each installed in a different
directory, independant of each other.
$ ls /usr/java/
j2sdk1.4.2_06 j2sdk1.4.2_12 j2sdk1.4.2_13 jdk1.5.0_05 jdk1.5.0_11
jre1.5.0_06
$
The only reason you have java in your path, and a java plugin
automatically in your browser is because of the java-1.4.2-compat rpm.
This rpm set's all your paths correctly and puts in a link for the plugin.

Personally, I would love to update to the latest 1.5 (I'd wait until 1.6
is more stable before updating to it.)
The problem is, that from what I've been told, there are lots of
critical programs that people are running that depend on the version of
java, and many of these are java 1.4.2 dependant.
Also, the java 1.5 doesn't remove the old 1.4.2. So the update wouldn't
be automatic.
