Hibernate映射異常在線程「主要」java.lang.ExceptionInInitializerError由無效映射在配置

Question

我試圖在互聯網上找到休眠設置映射示例，而我在運行我的HibernateUtil Java類時遇到以下問題。但是，編譯類和pojo文件時不會遇到任何問題。

... 6 more 

這裏是我的employee.hbm.xml

<hibernate-mapping> 
 
    <class name="PoJo.Employee" table="employee" catalog="empl" optimistic-lock="version"> 
 
     <meta attribute="class-discription"> 
 
      This class contains the employee details. 
 
     </meta> 
 
     <id name="id" type="int" column="id"> 
 
      <column name="id" /> 
 
      <generator class="native" /> 
 
     </id> 
 
     
 
     <set name="certificates" cascade="all"> 
 
      <key column="employeeId"/> 
 
      <one-to-many class="Certificates"/> 
 
     </set> 
 
     <property name="fname" type="string" column="fname"> 
 
      <column name="fname" length="20" /> 
 
     </property> 
 
     <property name="lname" type="string" column="lname"> 
 
      <column name="lname" length="20" /> 
 
     </property> 
 
     <property name="salary" type="int" column= "salary"> 
 
      <column name="salary" /> 
 
     </property> 
 
    </class> 
 
</hibernate-mapping>

而且，這裏的代碼中，我得到的問題

public class HibSetMap { 

private static SessionFactory sessionFactory; 


public static void main(String[] args) { 

try { 
     // Create the SessionFactory from standard (hibernate.cfg.xml) 
     // config file. 
     sessionFactory = new Configuration().configure().buildSessionFactory(); 
    } catch (Throwable ex) { 
     // Log the exception. 
     System.err.println("Initial SessionFactory creation failed." + ex); 
     throw new ExceptionInInitializerError(ex); 
    } 
    } 

部分請幫幫我！！
