String jarpath =  System.getProperty("user.dir") + "/config/externalConfig.properties";
try {
     FileInputStream in = new FileInputStream(jarpath);
     externalResourceFile.load(in);

     System.out.println(externalResourceFile.getProperty("indexPath"));

} catch (Exception e) { e.printStackTrace(); }
