[kaffe] kaffe and javax

[Gianluca Moro]

Hi all,

running some demos on my kaffe port (kaffe 1.1.6, compiled
for mips machine, using Tiny-X), I testet successfully
some programs using awt, now, I have a demo using swing,
and the program fails as it do not find
javax/swing/JComponent.setDropTarget!

When I run it with:

LD_PRELOAD=/usr/X11R6/lib/libX11.so:/usr/lib/libpng.so:/usr/lib/libz.so:/usr/local/lib/libjpeg.so
 kaffe -Dkaffe.awt.nativelib=xawt
-Xbootclasspath/p:/home/AMDgiammy/kaffe-1.1.6/kaffeawt.jar JButtons

I get the following error:

java.lang.NoSuchMethodError:
javax/swing/JComponent.setDropTarget(Ljava/awt/dnd/DropTarget;)V
   at javax.swing.JComponent.<init> (JComponent.java:413)
   at javax.swing.JRootPane.<init> (JRootPane.java:499)
   at javax.swing.JFrame.createRootPane (JFrame.java:214)
   at javax.swing.JFrame.getRootPane (JFrame.java:199)
   at javax.swing.JFrame.frameInit (JFrame.java:151)
   at javax.swing.JFrame.<init> (JFrame.java:113)
   at JButtons.<init> (JButtons.java:15)
   at JButtons.main (JButtons.java:11)

It seems it do not find swing library: is it correct?
I have looked into rt.jar (compiled on host PC and the copied on
MIPS machine), and I see am entry

 -rw-rw-r--     24643  20-Oct-2005  08:37:38 
javax/swing/JComponent.class

so I think the swing library is present.

Do I need to enable some flags when running the demo?
How can I tell where to find the library? 


thanks for the help

Here the example code:

import java.awt.*;
import javax.swing.*;

/** Simple example illustrating the use of JButton, especially
 *  the new constructors that permit you to add an image.
 *  1998-99 Marty Hall, http://www.apl.jhu.edu/~hall/java/
 */

public class JButtons extends JFrame {
  public static void main(String[] args) {
    new JButtons();
  }

  public JButtons() {
    super("Using JButton");
    //WindowUtilities.setNativeLookAndFeel();
    //addWindowListener(new ExitListener());
    Container content = getContentPane();
    content.setBackground(Color.white);
    content.setLayout(new FlowLayout());
    JButton button1 = new JButton("Java");
    content.add(button1);
    ImageIcon cup = new ImageIcon("images/cup.gif");
    JButton button2 = new JButton(cup);
    content.add(button2);
    JButton button3 = new JButton("Java", cup);
    content.add(button3);
    JButton button4 = new JButton("Java", cup);
    button4.setHorizontalTextPosition(SwingConstants.LEFT);
    content.add(button4);
    pack();
    //setSize(500, 200);
    setVisible(true);
  }
}
