Hibernate：javax.naming.NoInitialContextException（使用Hibernate生成的DAO）

Question

我是Hibernate的新手。從Eclipse靛藍使用Hibernate 3.0。

這裏討論的主題和答案沒有幫助，Hibernate: javax.naming.NoInitialContextException (Component Mapping via Annotations) 即我嘗試從會話工廠中刪除名稱，仍然出現錯誤。

我錯過了什麼嗎？有人能幫忙嗎？

誤差如下：

Feb 6, 2013 3:59:05 PM PatternsHome getSessionFactory

Hibernate配置文件：

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
            "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
<session-factory> 
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> 
    <property name="hibernate.connection.password">root</property> 
    <property name="hibernate.connection.url">jdbc:mysql://localhost/test</property> 
    <property name="hibernate.connection.username">root</property> 
    <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> 
    <property name="show sql">true</property> 
    <mapping resource="hibernate_db_mapping.hbm.xml"/> 
</session-factory> 
</hibernate-configuration> 

由Hibernate生成的DAO文件和輪廓被給定爲：

public class PatternsHome { 

private static final Log log = LogFactory.getLog(PatternsHome.class); 

private final SessionFactory sessionFactory = getSessionFactory(); 

protected SessionFactory getSessionFactory() { 
    try { 
     return (SessionFactory) new InitialContext() 
       .lookup("SessionFactory"); 
    } catch (Exception e) { 
     log.error("Could not locate SessionFactory in JNDI", e); 
     throw new IllegalStateException(
       "Could not locate SessionFactory in JNDI"); 
    } 
} 
    ..... 
    } 

Answer 1

I」我不能獨立完成這項工作。但是我創建HibernateUtil的泛型DAO和使用

sessionFactory = new Configuration().configure(new File("hibernate.cfg.xml")).buildSessionFactory(); 

創建SessionFactory的使用

Session session = HibernateUtil.getSessionFactory().openSession(); 
    Transaction transaction = null; 
    try{ 
     transaction = session.beginTransaction(); 
     session.save(myData); 
     transaction.commit(); 
     System.out.println("Data is Saved"); 
    }catch(Exception e){ 
     e.printStackTrace(); 
    }finally{ 
     session.close(); 
    } 

這個工作訪問DB在我的DAO。
