I assume from your install steps that you're using the package
downloaded from Sun's website. This java install goes into /usr/java/
which is not in your path by default.

You won't with this rpm, as it's still running /usr/bin/java which is
a placeholder type file.

Yes, it's installed but since it is not in your path, so unless you
run it directly with /usr/java/jre-xxxxx/bin/java it won't work.
If all you need is the runtime environment, you can install this from
dag's repository (dag.wieers.com/home-made/j2re/ install instructions
for the repo at http://dag.wieers.com/home-made/apt/FAQ.php#B4 )
If you want to use what you already have, you will need to add an
entry to your path. You can do this on a per-user basis by editing the
.bashrc or .bash_profile files with an entry like
PATH=$PATH:/usr/java/jre-xxx/bin
export PATH
Of the two, I'd rpm -e what you've already got installed, and ensure
that the /usr/java/ dir is gone (I don't really trust sun's packaging)
and install the packages from dag's repo. They're quite good, and
significantly more user friendly.
