Try the following class (copy of test/regression/HelloWorldApp.java):
class HelloWorldApp {
	public static void main (String args[]) {
		System.out.println("Hello World!");
	}
}

Compile it and run kaffe HelloWorldApp

Could be not defined as kaffe is a shell script that place
Klasses.jar, pizza.jar (and classes.zip if found) in it.

In any case, never set Sun classes.zip in CLASSPATH before
Klasses.jar.

Is in SimpleFrame the main method is defined ?
Remember, it must be "public static void main(String [])"

As you write before, you just downloaded the binary.
I don't know if it contains images dynamic libraries :(
The previous error is due to kaffe libawt.so that was compiled
with png (maybe also gif and jpeg) support.
You need an installed version of png (maybe also gif and jpeg).

You can find link to jpeg in the "Links" page of Transvirtual.
I forgot where I found png, may be in a /pub/gnu mirror ?

Also note that kaffe-1.0.b3 (8 Dec 1998) have some bugs already
fixed in CVS tree.
