        Properties props = new Properties();

        InputStream inputStream = this.getClass().getClassLoader()

            .getResourceAsStream(propFileName);



        if (inputStream == null) {

            throw new FileNotFoundException("property file '" + propFileName

                + "' not found in the classpath");
