OK, here the exact instructions where to download and what to do with it:

Visit the http://java.sun.com/j2se/1.4.2/download.html page, go to section "Download J2SE v 1.4.2_02", choose the Downloadbutton on "Linux RPM in self-extracting file" in the "SDK"-column, then read the license-agreement if you want to, scroll to the bottom and click "ACCEPT", download the "j2sdk-1_4_2_02-linux-i586-rpm.bin (as said on homepage: about 35 MB to download), execute the file ./j2sdk-1_4_2_02-linux-i586-rpm.bin and read the license agreement again and agree with their terms with "yes" , it's unpacking the j2sdk-1_4_2_02-linux-i586.rpm file into current directory, execute the rpm-file with rpm -iv j2sdk-1_4_2_02-linux-i586.rpm, let it work...
Then java is installed in /usr/java/j2sdk1.4.2_02

But, to have MySQL-support with Java, we need the MySQL Connector/J 3.0:
Visit the http://www.mysql.com/downloads/api-jdbc-stable.html page,
choose a compressed Version (*.tar.gz or *.zip, whatever you want) and download it. Open the compressed file you downloaded with your favourite archiver and search for a file called "mysql-connector-java-3.0.9-stable-bin.jar", uncompress it and copy this file to the following directory: /usr/java/j2sdk1.4.2_02/jre/lib/ext

Now we have installed java, but the disadvantage is that we need to call the java-interpreter with the whole path (i.e. /usr/java/j2sdk1.4.2_02/bin/java myjavaclassfile).
How to improve this situation: add the /usr/java/j2sdk1.4.2_02/bin to your PATH-variable.
:thumbs:
Does anyone have the instructions for adding this to the PATH variable for system level calls, or so it's in everyone's PATH when they logon or not?

Not sure on mandrake, but probably look into altering

/etc/profile

or you can just go into

cd /usr/local/bin

and do

ln -s /usr/java/j2sdk1.4.2_02/bin/java java (creates a symlink)

repeat for any of the other commands
