Dateien über Clipboard kopieren

[wurtzel]

Hallo

ich bin gerade an einem Projekt bei dem ich Dateien (Bilder .wmf, .gif, .png) in das Clipboard bringen muß damit sie von anderen Anwendungen eingebunden werden können (z.B Powerpoint)
dies sollte von der Kommandozeile aus funktionieren.

die folgende variante funktioniert leider nur bei Powerpoint 2003 und openoffice
wo liegt das problem das es nicht bei älteren versionen funktioniert

    public void copytoClipboard(String content)
    {

// content ist der Dateiname
        Vector fileVector = new Vector();
        File f = new File(new FileName(content).toString());
        if (debug) System.out.println("3" + f.getPath());
        f = f.getAbsoluteFile();
        if (debug) System.out.println("4" + f.getPath());
        fileVector.add(f.toString());
        int wert = fileVector.size();
        if (debug) System.out.println("5 " + wert);
        JList dragFileLister = new JList(fileVector);
        // dragFileLister.setDragEnabled(true);

        dragFileLister.setTransferHandler(new ListTransferHandler(fileVector));
        final Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
        TransferHandler handler = dragFileLister.getTransferHandler();
        handler.exportToClipboard(dragFileLister, clipboard, TransferHandler.COPY);

    }

Hm, du koenntest dir mal angucken, wie das in den aelteren Versionen implementier ist....in dem du von da aus was in die zwischenablage legst und dann wieder mit Java ausliest, in dem gleichen Format musst du das auch wieder reinstecken.

Die vom Explorer erzeugten ZA Formate
Shell IDList Array
CF_HDROP
DataObjectAttributes
Preferred DropEffect
Shell Object Offsets
FileName
FileNameW

Die vom JAVA erzeugten ZA Formate
Preferred DropEffect
CF_HDROP

Mein Problem ist wie erzeuge ich die anderen
