    public static void main(String[] args) {
        System.out.println("start");
        // get a default DataSourceService
        Object service = ServiceManager.lookupService(DataSourceService.id);

        if (service != null) {
            DataSourceService ds = (DataSourceService) service;

            try {
                // get default connect;
                Connection conn = ds.getConnection();
