Impossible de trouver le modèle StringTemplate

Question

J'essaie de créer une application wiki dans google app engine. J'utilise le modèle de chaîne. Mais je ne comprends pas la hiérarchie des fichiers de modèles.

Voici le code.

• importations nécessaires effectuées.

  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; 
  } 
  
  } 
  

Et est la structure du répertoire ici.

Essayez d'éviter '-' dans les noms de modèle. Ter
