Is there any way to use information kept in Clipboard in Java applet?
What I need is to use a screen-shot image inside Java applet for Whiteboard purposes.

Pure Java, don't thinks so. With MSIE and MSJ++ may be.
You can do it with native code, but implementing a shared .dll that does the grabbing from the clipboard. Anyway, you need to sign your applet in order to be able to download your dll and load it.

Take a look here....




public void clpbrd()
    {
        System.out.println("Clipboard stuff");
        try
        {
//blah blah
            Clipboard clip = this.getToolkit().getSystemClipboard();
   
            if(clip == null) throw new IOException("No clipboard in scene");
     //blah blah
            Transferable trans = clip.getContents(this);
    //blah blah
            if( trans == null) throw new IOException("Clipboard Empty");
     //******************
            String s = (String) trans.getTransferData(DataFlavor.stringFlavor);
//***************
            _textArea.replaceRange(s, _textArea.getSelectionStart(),
                                          _textArea.getSelectionEnd());
        }
        catch(Exception e)
        {
//do smthng.  
        }
    }
