In openSUSE 11.3 64bit java apps don't work.

This is what I have installed:
java-1_5_0-gcj-compat-32bit
java-1_6_0-sun
java-1_6_0-sun-alsa
java-1_6_0-sun-devel
java-1_6_0-sun-plugin

When I go to the java site to check java it says Im up to date, so everything seems fine, but many apps that I use do not work. The java logo appears, it shows the loading bar and then it shows an empty box.

It used to work perfectly in openSUSE 11.2, but I recently upgraded to 11.3 and now it does not work.

I need this for my college and for work, so please help. I am stuck!

just in case all the java 1.6 are version 1.6.0.u22-1.2.1, and the 1.5 is 1.5.0.0-125.4, and my firefox is 3.6

The website I am trying that does not work is this one
