Hi! I posted this on Netbeans thread as well and just trying my luck over here... just in case.

I'm currently using Vista and when I run a simple project on Eclipse, this error occur:

All I'm testing for is just this simple code...

Java Code: 
public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        int a = 20;
        int b = a;
        
        System.out.println("Hello World! "+b);
    }

}
And this is the error message when I try to run the debug...
