這裏HibernateUtil類：

公共類的HibernateUtil { private static final SessionFactory sessionFactory;

static { 
    try { 
     // Create the SessionFactory from hibernate.cfg.xml 
     sessionFactory = new Configuration().configure().buildSessionFactory(); 
    } catch (Throwable ex) { 
     // Make sure you log the exception, as it might be swallowed 
     System.err.println("Initial SessionFactory creation failed." + ex); 
     throw new ExceptionInInitializerError(ex); 
    } 
    } 

    public static SessionFactory getSessionFactory() { 
    return sessionFactory;

}}

，我想用這種方式：

Session session = HibernateUtil.getSessionFactory().openSession(); 

Transaction transaction = session.beginTransaction(); 
     User testuser = (User)session.load(User.class, "kennung"); 
     transaction.commit(); 
     Window.alert(testuser.getFirstname());

你應該在你/war/WEN-INF/lib/文件夾中有commons-logging-api-1.1.1.jar（或者是最新的版本）。將它包含在你的類路徑中是不夠的。

UPDATE：

另一種可能性是，你正在運行到禁區類：

感謝你的答案，但現在有另一個錯誤： Schwerwiegend：問題解析配置/hibernate.cfg.xml org.dom4j.DocumentException：取出時超時：http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd嵌套異常：取出時超時：http：// www。 hibernate.org/dtd/hibernate-configuration-3.0.dtd – realizze

請原諒我的問題，但這是我第一個gwt/hibernate項目。 但舊錯誤未解決，並且出現新錯誤： 初始會話創建工廠failed.org.hibernate.MappingException：需要使用AnnotationConfiguration實例 – realizze

這是一個完全不同的問題。請接受這個問題的答案，並要求一個新的答案。在那個新問題中顯示錯誤信息。 –
