Thank you, that's actually what I did after nothing helped. So is there no way to set classpath using only command line? As I see it sets classpath only for one session, but it doesn't work even this way. I mean when I type "set classpath = C:\Java Programs\Classes" it seems to work, and then I type "set classpath" and it displays "classpath = C:\Java Programs\Classes", and everything looks just fine, but when I try "java Hello" it doesn't work! I know that it works perfectly the way you described, but again, the question is "How can I do the same using command line". Thank you.
