Clipboard problems

Question

Im working on a simple encryption applet, but I have trouble with copying and pasting text from other applications into my applet.
Within my applet, i can use Ctrl + C or Ctrl + V to copy and paste text but the applet does not seem to respond to text i copied from somewhere else, and I cannot paste text from my applet to any other application either.
So, I tried looking in the Java documentation, and I came across the awt toolkit where i can access the system clipboard. I used their example on how to use it, but even with that, i have no luck. when I try to cut / paste nothing happens at all.
this is a code snippet for the copy and paste segment.
public void actionPerformed(ActionEvent e) {
         //Paste text
         if (e.getActionCommand().equals(PASTE)){
               Transferable t =
                       Toolkit.getDefaultToolkit().getSystemClipboard().getContents(null);
               try {
                    if (t != null && t.isDataFlavorSupported(
                         DataFlavor.stringFlavor)) {
                    String s = (String)t.getTransferData(
                        DataFlavor.stringFlavor);
                      input.setText(s); //input is a JTextArea
               catch (UnsupportedFlavorException e2) {
               catch (IOException e2) {
         //Copy text
         if (e.getActionCommand().equals(COPY)){
              StringSelection out = new StringSelection(output.getText()); //output is a JTextArea
              Toolkit.getDefaultToolkit().getSystemClipboard().setContents(out, null);
}I'd appreciate any help. I'm stumped.
Thanks,
Alvin

try this:
for Placing Text on the System Clipboard
StringSelection ss =
   new StringSelection("aString");
// The following 2 lines of code must be
// on the same line
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(ss, null);for Retrieving Text from the System Clipboard
// The following 3 lines of code must be
// on the same line
Transferable t = Toolkit.getDefaultToolkit().getSystemClipboard().getContents(null);
try {
   if (t != null && t.isDataFlavorSupported(
     DataFlavor.stringFlavor)) {
       String s = (String)t.getTransferData(
         DataFlavor.stringFlavor);
       process(s);
} catch (UnsupportedFlavorException e) {
} catch (IOException e) {
}
