cannot find symbol?

[lbrtchx]

Hi,

I am trying to create an abstract class with their particular
implementations for the different decompress formats java supports (I
know it works. I have done it before), but I am getting some
uncomprehensible "cannot find symbol" error, even though I did compile
the implementation classes first and I am making them accessible
through the classpath

What does this error mean in this case?

How can I fix it?

 What does this error mean in this case?

Java is case sensitive, from a-Z.

these stupid on your face bugs/erros can still bite you lbrtchx

dkPrx [] had better be defined as an array in scope.

Your listings imply that you have your classes in the default package, that
you have .class and .java files in the same directory, and that you do your
work as root. That's three mistakes, if you actually did those things.
