novice javac problem

[Tony Kimball]

I'm installing kaffe for the first time, version 0.8.2 on FreeBSD.
I have not been able to compile anything:

; javac HelloWorldApp.java
HelloWorldApp.java:1: Superclass java.lang.Object of class HelloWorldApp not found.
class HelloWorldApp {
      ^
1 error

Can anyone diagnose or suggest how I should myself go about diagnosing
this problem?

Thanks,
