    System.out.println("Refresh bar Chart");
    response.setContentType("image/png");
    OutputStream outstream = response.getOutputStream();
    try {
        JFreeChart chart = getChartViewer();
        ChartUtilities.writeChartAsPNG(outstream, chart, 500, 300);
        System.out.println("Created bar Chart");
        return SUCCESS;
    } finally {
        outstream.close();
        response.flushBuffer();
    }
}
