Hi Luis,

The class format error is because you are using jdk1.2beta3 as against
jdk1.1.5
I got the same error when i tried jdk1.2beta3

So you will have to download jdk 1.1.5 and it will work fine.

Note: You will come across this class format error if you have 2 class
files A & B; A depends on B. If you compile A, it looks at the format of
B and compiles and runs fine. If now you were to change B and run A
without recompiling A, there would be a class format error.
