Quaqua look and feel issues

I am using quaqua look and feel in linux and windows. it was working fine till I got the problem witn JOptionPane. When the code opens the JOptionPane using the line

JOptionPane.showInternalConfirmDialog(
    pos_main.category_layer, "Give Rewards Now!!", "Loyalty", 1);

I am getting the following exception,

Warning: class ch.randelshofer.quaqua.osx.OSXApplication couldn't load library "quaqua". 
java.lang.UnsatisfiedLinkError: no quaqua in java.library.path

--EDIT--

System.out.println(System.getProperty("java.library.path")); shows the following output.

It looks like you need to check through the steps for Integration Into an Application.

Addendum: On Mac OS X, /System/Library/Java is the root of several system properties, such as java.home and java.library.path. It's where the resources required for JOptionPane live. Linux and Windows are not supported.

Addendum: On Ubuntu 10.04, the JOptionPane demo runs fine; you can use this approach, which is suitable for development purposes only.
