I'm sorry to bother with so newbie questions but it is really annoyoing
me!

I have the quintessential error of:

Exception in thread "main" java.lang.NoClassDefFoundError:
ClassName/class

The directory i'm using is:

C:\work\java

I'm using Windows XP and my CLASSPATH has these values:

.;C:\work\java;

Is there something else I'm missing!

Thank you very much!

Hello,

I guess that you start the application with 'java ClassName.class'.

Use 'java ClassName' (without the file extension) instead. The argument
is a class name, not a file name.

Cheers,

Thank you very much! It works!

Is this something specific of Windows XP or the newest version of Java?

Again, thank you very much.

No, on every platform, every version of java works by typing "java"
followed by the qualified class name (and NOT the filename of the class
file).
