| Hello, all.
I'm using NetBeans 4.1 on winXP to build my very first applet, and i
think I'm missing a very basic concept about the way applets are
deployed.
My applet was running fine in the browser until I added some Java
Imaging Utilities (JIU) classes to my project. Now, while the applet
still compiles and runs in the NetBeans environment, I can't get it to
run inside the browser.
I get the following errors in the java console:
Java Plug-in 1.5.0_06
Using JRE version 1.5.0_06 Java HotSpot(TM) Client VM

-------------------------
My main applet class is in a directory called "classes", and I've
placed the entire JIU directory tree in the same directory
(classes/net/sourceforge/jiu/...)
The code and a screenshot of the directory structure can be found at:

Please be gentle. I know it's ugly and probably breaks a lot of
conventions and rules.
Any help would be greatly appreciated.
