NoClassDefFoundError error

[pramod talekar]

Hello,

I have created a .class file from a .java file on my desktop (C:\Documents and Settings\ptalek\Desktop\MyFirstJava.java) & (C:\Documents and Settings\ptalek\Desktop\MyFirstJava.class).

Below is the code for MyFirstJava.

class MyFirstJava {
    public static void main(String[] args) {
        System.out.println("Java rocks.");
    }

}

But I'm unable to run this program using the java command.

I'm using following commands in the command prompt:

C:\Documents and Settings\ptalek\Desktop> javac MyFirstJava.java
C:\Documents and Settings\ptalek\Desktop> java MyFirstJava   

I got the below error :

C:\Documents and Settings\ptalek\Desktop>java MyFirstJava
Exception in thread "main" java.lang.NoClassDefFoundError: MyFirstJava
Caused by: java.lang.ClassNotFoundException: MyFirstJava

Could not find the main class: MyFirstJava.  Program will exit.

Please advise.

Use java -cp . MyFirstJava .

Typical classpath problem indeed. Check the JavaRanch FAQ. This document and others will surely help you avoid many pitfalls. Then again, stepping into pitfalls means you have to get out of them and that learning process is good for you

Cheers,

Thanks Seetharaman & Wim.

It's working now.
The doc I'm referring to doesn't show this classpath statement

Thank you so much.
