JDialog displaying progress

Hi,
I'm trying to display on modal JDialog progress of copying files. I've
used SwingWorker for copying the files, so it won't freeze the JDialog,
but then I need to get the response to parent frame (if the files were
copied succesfully). I've tried StringWorker.get but when I use this
method the JDialog won't show up :(

//Creating dialog from MainFrm and executing download method
        final CopyDlg copyDlg = new CopyDlg(this, true);
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                copyDlg.setVisible(true);
            }
        });

        try {
                sWorker = copyDlg.download(toCopy,
currentDirectory.getPath(), remoteDirectories, ftp, jLogTxtArea);
                System.out.println(sWorker.get()); //without this line
it's working ok, but I don't get response : } catch (InterruptedException ex) {
                ex.printStackTrace();
           }
//-----------------------------------------------------------------------------------------------------------------------------------------------
//method download in CopyDlg class
    public SwingWorker download(final ArrayList foDs, final String
where, final FDArrayList directories, FtpClient ftp, JTextArea
jLogTxtArea) throws InterruptedException {
        this.ftp = ftp;
        this.jLogTxtArea = jLogTxtArea;

        SwingWorker sWorker = new SwingWorker<Boolean, Void>() {
            public Boolean doInBackground() throws Exception {
                String foD;

                for (int x = 0; x < foDs.size(); x++){
                    foD = (String) foDs.get(x);

                    if (!downloadFoD(foD, where, directories))
                        return false;
                }

                return true;
            }

            public void done(){
                setVisible(false);
            }
        };

        sWorker.execute();

// try {
// System.out.println(sWorker.get());
// } catch (InterruptedException ex) {
// ex.printStackTrace();
// } catch (ExecutionException ex) {
// ex.printStackTrace();
// }

        return sWorker;
    }

I'm newbie to Java so please be patient :)
Any help is appreciated
Thanks in advance ;)
