Exception in thread "main" NoClassDefFoundError

[ShaunRobert Williams]

Hi, im trying to comple this code on a Mac running OS X 10.4.

import javax.swing.JMenuBar;
import javax.swing.JFrame;
import MacGUI.MacJMenuBar;
 
public class MainFrame extends JFrame {
    /**
     * Create the GUI and show it.  For thread safety,
     * this method should be invoked from the
     * event-dispatching thread.
     */
    public MainFrame(){
       super("Hiemdall BETA");
   setJMenuBar(getMacMenuBar());
   setSize(400,400);
       setVisible(true);
    }

private JMenuBar getMacMenuBar() {
return new MacJMenuBar();
}
 
    public static void main(String[] args) {
new MainFrame();
    }
} 

package MacGUI;
 
import javax.swing.JMenuBar;
import javax.swing.JMenu;
 
public class MacJMenuBar extends JMenuBar{
  public MacJMenuBar(){
    add(new JMenu("File"));
    add(new JMenu("Edit"));
    add(new JMenu("Format"));
    add(new JMenu("Window"));
    add(new JMenu("Help"));
  }
}

Both files are in the same dir. I do a javac *.java
and then java -classpath . MainFrame

I Get: Exception in thread "main" java.lang.NoClassDefFoundError: MacGUI/MacJMenuBar

Any ideas?
Thanks a bunch.

The problem is the package statement.

Try removing that or putting that source file in a directory that matches the package.

Removing the package statement didnt fix it, but moving the file to its proper directory did.

Thanks Keith!

Oops, sorry.

If you remove the package statement in the second, you need to remove the import statement in the first.
