Exception in thread "main" java.lang.NoClassDefFoundError: ClassName/class
I have the same problem too with java applications, I have a book examples (i don't know how it's named, coz i found them in internet alone, but all of them describe Swing GUI). When i compile and run them
javac JavaSource.java
java JavaClass (not .class)
i get the same erro. What can it be. For example thwe smallest example from this book is:
import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;
public class OvalBorder implements Border

m_h=6;
}
public OvalBorder(int w, int h) {
