[code]javac[/code] works, [code]java[/code] does not work.

Question

I have installed the Java 2 SDK Standard Edition v1.3.1_01. I have set the path in the autoexec.bat file. I created the file WhatsUpDoc.java containing:
public class WhatsUpDoc{
  public static void main(String[] args){
    System.out.println("What's up Doc?");
}At the DOS prompt, when I type: javac WhatsUpDoc.java there is no compilation error and the WhatsUpDoc.class file is created. But, when I type java WhatsUpDoc at the DOS prompt, I get:
Exception in thread "main" java.lang.NoClassDefFoundError: WhatsUpDocI have compiled several applets working just fine on a web page. Why I cannot run this simple application?
Thank you for your help.

Answer 1

I have installed the Java 2 SDK Standard Edition
v1.3.1_01. I have set the path in the
autoexec.bat file.What have you set the CLASSPATH to? It should be ".;%JAVA_HOME%\jre\lib\rt.jar". It looks like the CLASSPATH is wrong, so java can't see the class in the current directory. :-/
