Cannot get hello world to run?!

Question

Ack, an IDE is a terrible thing. I recently tried to compile/run a java program the old fashioned way (from DOS command prompt), and I can't even get a simple hello world prog to run!
I've got a file "Hello.java" with the code
public class Hello {
public static void main(String[] args) {
System.out.println("hello, world!");
} from the command prompt, i then do "javac Hello.java", which works fine, and then a "java Hello". Unfortunately, "java Hello" says "NoClassDefFoundError: Hello"... I can't for the life of me figure out why something so simple isn't working. Anyone? I'm getting pretty desperate here lol...

hi,
may be your class path doesn't set.
set classpath=.;%classpath%;copy and paste it into your current dir and try once
