    我是JPA的新手。我正在尝试创建EJB 3.0+JPA(Hibernate)应用程序。当我将数据持久化到数据库中时,会出现以下异常。

    SessionBean方法 

    @PersistenceUnit private EntityManagerFactory emf;

@Override
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public void insterCustomerDetails(Customer customer) {
    // TODO Auto-generated method stub
    try{
        //System.out.println("properties:::"+em.getProperties());
        //System.out.println("Model :::"+em.getMetamodel());
    System.out.println("Name ::::" + customer.getName() + "::customer id ::"+customer.getCustomer_id()+"::email::"+customer.getEmail_id()+"::address::"+customer.getAddress()+
            ":::ph number::"+customer.getPhNumber());
    EntityManager em = emf.createEntityManager();
    EntityTransaction et = em.getTransaction();
    et.begin();
    em.persist(customer);
    et.commit();
    em.close();
    }catch(Exception e){
    e.printStackTrace();
}
}

    持久性.xml 

    <persistence-unit name="RetailUnit" >
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <!-- the JNDI data source-->
    <jta-data-source>java/customer</jta-data-source>
    <properties> 
        <!-- if this is true, hibernate will print (to stdout) the SQL it executes, 
            so you can check it to ensure it's not doing anything crazy
             <property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.ClientDriver"/>
             <property name="hibernate.connection.url" value="jdbc:derby://localhost:1527/company;create=true" />
          <property name="hibernate.connection.username" value="user" />
          <property name="hibernate.connection.password" value="123" /> -->
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
        <!-- since most database servers have slightly different versions of the 
            SQL, Hibernate needs you to choose a dialect so it knows the subtleties of 
            talking to that server -->
        <property name="hibernate.dialect" value="org.hibernate.dialect.DerbyDialect" />
        <property name="hibernate.archive.autodetection" value="class"/>
        <!-- this tell Hibernate to update the DDL when it starts, very useful 
            for development, dangerous in production -->
        <property name="hibernate.hbm2ddl.auto" value="create" />
    </properties>
</persistence-unit>
</persistence>

    如果在EJB中使用,则不需要手动使用事务——默认情况下,所有方法都是事务性的——您甚至可以 @TransactionAttribute(TransactionAttributeType.REQUIRED) 在您的方法上,这是默认设置。

    如果没有可用的事务,则事务在方法启动时开始,并在方法返回时提交。不需要手动交易控制。

    如果您没有令人信服的理由使用 EntityManagerFactory ,可能最好注入 EntityManager 正确,而不是在每次调用时从EMF中检索: 

    @PersistenceContext 
private EntityManager em;
