Java - system clipboard problem

Question

I'm trying to put text from a java program to the system clipboard (OS) and I can't make it work.
I've included a small code example in this post.
import java.awt.datatransfer.*;
import java.awt.*;
import java.awt.Toolkit.*;
class ClipTest{
public static void main(String[] args){
new ClipTest();
public ClipTest(){
StringSelection clip = new StringSelection("hello");
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
clipboard.setContents(clip,clip);
System.exit(0);
After running the program I would expect to have "hello" on my System clipboard. But I don't. Nothing has been transfered to the clipboard.
I'm running java1.3.1 on IRIX and I have tryed Linux as well.
Am I doing something wrong here? Please enlighten me.

Answer 1

That's a thought. but take this code example though:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MyTextArea extends JTextArea implements ActionListener{
JTextArea m_txt;
JPopupMenu m_menu;
public MyTextArea(){
super();
m_txt=this;
addMouseListener(new RightMouseListener());
m_menu = new JPopupMenu("Menu");
JMenu item = new JMenu("Edit");
m_menu.add(item);
JMenuItem item1 = new JMenuItem("Copy");
item1.addActionListener(this);
item1.setActionCommand("copy");
item.add(item1);
class RightMouseListener extends MouseAdapter{
public void mouseClicked(MouseEvent e){
if(e.getModifiers()==InputEvent.BUTTON3_MASK){
m_menu.show(m_txt, e.getX(),e.getY() );
public void actionPerformed(ActionEvent e){
if (e.getActionCommand().equals("copy")) {
copy();
If you use this component in a dialog or something, type some text in it, make a selection, righclick and choose copy from the edit menu, I get the same result, and I guess it will work at your Windows platform?
