Answer 1

You need to use SwingWorker for updating UI while you do long background process.

Read tutorail for SwingWorker and Concurency in Swing.

Answer 2

You can use a SwingWorker to do the calls in the background and update the progress bar in the Event Dispatching Thread (a.k.a. EDT). Something like this:

SwingWorker<Void, Integer> worker = new SwingWorker<Void, Integer>() {
    @Override
    protected Void doInBackground() throws Exception {
        int processed = 0;
        DefaultTableModel model = (DefaultTableModel) data.getModel();
        for (int count = 0; count < model.getRowCount(); count++) {
            //...
            String messege = csmt.getString(4);
            processed++;
            publish(processed / model.getRowCount() * 100);
        }
        return null;
    }

    @Override
    protected void process(List<Integer> list) {
        progressBar.setValue(list.get(list.size() - 1));
    }
};
worker.execute();
