When you install the jdk, it comes with everything from the jre
included, so you don't need to install the jre separately. Then all
you need to do after that is set an environment variable
JAVA_HOME=/usr/local/jdk1.5.0, and either add $JAVA_HOME/bin to your
path or symlink the appropriate binaries into /usr/local/bin

On Debian, the best way to install Java is to download the binary
installer and then use make-jpkg from java-package to create .debs of
Java that do the right thing.

On RPM based distros, the best way to install Java is to install the
.rpm
