java.lang.reflect.InvocationTargetException - applet with Arrays

Question

I'm tearing my hair out trying to figure out why this third applet I've written behaves just fine in BlueJ but throws a "java.lang.reflect.InvocationTargetException" when I try to view it in a browser. I am still pretty much a newbie and can't figure out where to look to see the full error logs, either. Please help.

Answer 1

To close the loop - we were meant to use unsigned .jars in the class. I had to move my arrays to the method and then it worked. So I didn't get to use my fancy instantiation but I understand a lot more about parameter availability. Thanks to all who responded.
