How to set classpath in WinXP Home edition

Question

Hello everyone,
Recently I have try to run the HelloWorld java code, but it come up with a error. (Exception in thread �main� java.lang.NoClassDefFoundError: HelloWorld)
Java programming Code:
public class HelloWorld {
public static void main (String args[]) {
System.out.println("Hello World!");
I also try to compile another simple program, and it come up with the simpler error, (Exception in thread �main� java.lang.NoClassDefFoundError: Add16And23)
Java programming Code:
public class Add16And23
     public static void main (String[] args)
          int sum;
          sum=16+23;
          System.out.println("The sum of 16 and 23 is " + sum);
HOW CAN I FIX THIS, I read other threads before, it say some about class path.
Do anyone know how to set it, in winXP?
Do anyone know the whole path that I should put in, in winXP?
What should I type in the (User variables for windows) and (System variables).
I have :
* (j2eesdk-1_4-dr-windows-eval) downloaded and installed;
*WinXP Home edition Version 2002 Service Pack 1
* My current Java path are (C:\Sun\AppServer\jdk\bin) in the (User variables for windows).
Please help!!!
Thank you all!!!

I'm also windows xp.
fllowing example:
java_home=c:\j2sdk1.4.2_03\bin
classpath=c:\j2sdk1.4.2_03\dt.jar;c:\j2sdk1.4.2_03\tool
.jarThis won't fix a thing.
When you run, do it like this:
java -classpath . HelloWorldNote the "dot" after -classpath. That tells the class loader to look in the current directory for the .class files it needs.
Read about how to run the javac.exe and java.exe tools in your javadocs. You'll have to learn about CLASSPATH. - MOD
