public void test() throws Exception {
 Configuration cfg = new Configuration();
 cfg.setDirectoryForTemplateLoading(new File("" + "./src"));
 cfg.setObjectWrapper(new DefaultObjectWrapper());

 Map<String, Object> root = new HashMap<String, Object>();
 root.put("user", "Koma");

 Map<String, String> latest = new HashMap<String, String>();
 root.put("latestProduct", latest);
 latest.put("url", "1.htm");
 latest.put("name", "product name");

 Template temp = cfg.getTemplate("test.ftl");
