The java program only reads class files.  So, you only worry about their 
location.  Whether you have to add every directory for your .class files 
depends on the structure of your code.  This is why packages are important.

If you have a program (test) with two packages (hello), (goodbye):

$HOME/test/
$HOME/test/hello/
$HOME/test/goodbye/

You would only need to add $HOME/test to your classpath.  The compiler 
(because of your package declarations in your java code) will find the hello 
and goodbye packages.

I'm not sure, but I suspect that your $CLASSPATH on windows includes the 
current directory (.).  If you did this on linux, you would get the same 
result and you could then cd to the location where your .class file is to run 
your program (provided it's not in a package).

You can do this by:

$ export CLASSPATH=.
