java 1.4.2 problem

Hi list, for a particular application I need java 1.4.2. SuSE Linux 8.2 which is running here comes with 1.4.1. What would be the correct way to install the updated version? I just finished trying a (Redhat?) rpm from Sun's web site which installs it in /usr/java instead of the SuSE default location in /usr/lib/java. After symlinking it seemed to work okay with my application but it broke other stuff, among other things galeon. Therefore I am now back to square 1 and would be very greatful to learn how to self-install this thing correctly. Best regards, Alex.
