More class path

I have read the entries about class path and understand that you no longer
use the environment method to set the path and now you enter the path at the
execution of you application.
What I don't know is where should I point my class path?
My path to Java is:

C:\Program Files\Java\sdk1.5.0_06

What do I add to that?
I am running WinXP

Thanks Bob Wright
