With main at somewhere else

I assume your problem is that the above code (plus some you omitted)
causes a window to be displayed at minimum size and with no content visible?

I don't use AWT (why dont you use Swing?) but the following "works"
under JDK 1.5 after I implemented a minimal main()

import java.awt.Dimension;
import java.awt.Frame;
import java.awt.Menu;
import java.awt.MenuBar;
import java.awt.MenuItem;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class LPRFrame extends Frame {

     public LPRFrame() {

         Menu menuFile = new Menu("File");
         MenuItem menuFileLoad = new MenuItem("Load Image");
         menuFile.add(menuFileLoad);

         Menu menuImg = new Menu("Image/Data");

         MenuBar menuBar = new MenuBar();
         menuBar.add(menuFile);
         menuBar.add(menuImg);

         setMenuBar(menuBar);
         setTitle("LPR");
         setSize(new Dimension(640, 480));
     }

     public static void main(String[] args) {
         LPRFrame frame = new LPRFrame();
         frame.addWindowListener(new WindowAdapter() {
             public void windowClosing(WindowEvent evt) {
                 System.exit(0);
             }
         });
         frame.setVisible(true);
     }
}

I also put the menu labels into the constructors to save a few lines of
source code.
