hi all!

i am almost finished with my knoppix 4.0.2 remaster. i still need to replace the currently installed java (v1.4.2_06) with the J2SDK v1.5.0_06.
is there an easy way to do this?
i already tried adding "debian unofficial" mirrors in /etc/apt/sources.list, "aptitude update" and "aptitude install sun-j2se5.0-jdk-binary".
it seems as there is no such package, although it is listed in the package list at http://www.debian-unofficial.org/packages.html .

any help?
