private static void listFilesFromDirectoryInsideAJar(String pathToJar,String directory,String extension) {
        try {
            JarFile jarFile = new JarFile(pathToJar);
            Enumeration e = jarFile.entries();
            while (e.hasMoreElements()) {
                JarEntry candidat = e.nextElement();
                if (candidat.getName().startsWith(directory) && 
                    candidat.getName().endsWith(extension))
                    LOG.info(candidat.getName());
            }
        } catch (IOException e) {
            LOG.error(e.getMessage(),e);
        }
    }
