QT/KDE Java does not run

Question

I decided to learn Qt Java and KDEJava. I found some demo code here but I can't get it to work.
It compiles fine.
$ javac -classpath $CLASSPATH:/opt/kde/lib/java/qtjava.jar ScribbleWindow.java
But does not run.
$ java -classpath $CLASSPATH:/opt/kde/lib/java/qtjava.jar ScribbleWindow
Exception in thread "main" java.lang.UnsatisfiedLinkError: no qtjava in java.library.path

Wiki says that
==> Kdebindings has been built with support for Java and GTK.
==> If you want to use these features use the following pacman commands:
==> 'pacman -S j2sdk'
==> 'pacman -S gtk'
I have kdebindings and j2sdk installed. After searching the forum I'm not sure if Wiki is right. Is kdebindings compiled with java support or not? Am I supposed to install or recompile something to get it working?

ummm, try it like this:
$ java -classpath $CLASSPATH:/opt/kde/lib/java/ ScribbleWindow
It gives different error:
$ java -classpath $CLASSPATH:/opt/kde/lib/java/ ScribbleWindow
