tried rpm -e kaffe
got the following

error: removing these packages would break dependencies:
kaffe is needed by wizard-3.2.1-5mdk
Now I now I could remove the wizard but I use it for Samba set up
(this is done and I really could dump it)

I then tried
mv /usr/bin/java /usr/bin/java.old
ln -s /usr/java/jre1.3.1_02/bin/java /usr/bin/java

The problem is I do not have jre changed jre to jdk and voila
it now works
