Не удается найти шаблон StringTemplate

Question

Я пытаюсь создать приложение wiki в Google приложении. Я использую шаблон String. Но я не понимаю иерархию файлов шаблонов.

Вот код.

• необходимые импортные товары сделаны.

  public class Add extends HttpServlet{ 
  
  protected void doPost(HttpServletRequest req, HttpServletResponse resp) 
      throws ServletException, IOException { 
  // TODO Auto-generated method stub 
  //super.doPost(req, resp); 
  DatastoreService datastoreService = DatastoreServiceFactory.getDatastoreService(); 
  
  String title = req.getParameter("title"); 
  Entity articleEntity = new Entity("Article", normalize(title)); 
  articleEntity.setProperty("title", title); 
  
  UserService userService = UserServiceFactory.getUserService(); 
  User user = userService.getCurrentUser(); 
  if(user != null){ 
      String author = user.getNickname(); 
      articleEntity.setProperty("author", author); 
  }else{ 
      String author = "Anonymous"; 
      articleEntity.setProperty("author", author); 
  } 
  
  String content = req.getParameter("content"); 
  Text myContent = new Text(content); 
  articleEntity.setProperty("content", myContent); 
  
  datastoreService.put(articleEntity); 
  
  resp.sendRedirect("index.jsp"); 
  } 
  
      private String normalize(String str){ 
  String trimmedLower = str.toLowerCase().trim(); 
  String urlReady = trimmedLower.replace(" ", "-"); 
  return urlReady; 
  } 
  
  } 
  

А вот структура каталогов.

Я получаю эту ошибку

Старайтесь избегать '-' в именах шаблонов. Тер
