The commandline for the above example in that case would be :

java -classpath /xyz/abc MyPackage.MyClass

That doesn't work for me although I have seen reference to it before
like that. Could it be that it doesn't work on Windows like that?

   It works for me on WinXP SP2:

java -cp "D:\Oliver's Documents\Workspace\Test\bin" D

   to run a class called "D" with no package whose classfile is in
"D:\Oliver's Documents\Workspace\Test\bin"

That does for me too. But put it in a package and it won't.

Interesting - Seems to work for me even with classes within a package -

Running TCPServer.class in package test :

java -classpath "C;\Documents and
Settings\Babu\workspace\TestServer\classes" test.TCPServer
Main: Listening for connections on port 2345

Testing on XP Home SP2

package test;

public class Test {
     public static void main(String[] args) {
         System.out.println("It works!");
     }
}

C:\>javac test/Test.java

C:\>java test.Test
It works!

C:\>cd test

C:\test>java -cp "C:\test" test.Test
Exception in thread "main" java.lang.NoClassDefFoundError: test/Test

C:\test>java -cp /test test.Test

What am I doing wrong here?
