Wildfly 8.2和Hibernate:无法注册同步

我试图在WIldFly 8.2中实现restfull服务。我想使用hibernate处理db

1） 我在wildfly的配置文件中创建了数据源

2） 我在管理控制台中检查了连接。它起作用了

3） persistence.xml：

 <?xml version="1.0" encoding="UTF-8"?>  
    <persistence version="2.0"  
        xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
        xsi:schemaLocation="  
            http://java.sun.com/xml/ns/persistence  
            http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">  
        <persistence-unit name="HSDB" transaction-type="JTA">  
            <jta-data-source>java:jboss/datasources/PostgreDataSource</jta-data-source>  
            <properties>  
                <property name="hibernate.hbm2ddl.auto" value="update" />  

                <property name="hibernate.show_sql" value="true" />  
                  <property name="format_sql" value="true" />  

            </properties>  
        </persistence-unit>  
    </persistence>  

rs文件：

  @Path("/")  
    public class HelloWorld {  

    @PersistenceUnit(unitName = "HSDB")  
        private EntityManagerFactory mEntityManagerFactory;  
    ...  

       @GET  
        @Path("/")  
        @Produces(MediaType.APPLICATION_XML)  
        @Consumes(MediaType.APPLICATION_XML)  
        public String getHelloWorldXML() {  
    //        EntityManagerFactory emf = Persistence.createEntityManagerFactory("HSDB"); //returns null  
    //        EntityManager em = emf.createEntityManager(); //null pointer exception on this line. emf is null  
            EntityManager em = mEntityManagerFactory.createEntityManager();  
            String id = "_def_";  
            Session session = (Session) em.getDelegate();  
            Transaction tx = null;  
            User person = null;  

            try {  
                tx = session.beginTransaction();  //<-- problem is here  
                person = (User) session.get(User.class, 7);  
                id = String.valueOf(person.getId());  
            } catch (HibernateException e) {  
                if (tx != null)  
                    tx.rollback();  
                e.printStackTrace();  
            } finally {  
                tx.commit();  
                session.close();  
            }  
            return "<xml><result>" + helloService.createHelloMessage("World")  + id + "</result></xml>";  


        }  
    }  

所以和数据库的连接是好的。但当我尝试在代码中使用它时，我遇到了以下错误：

将此属性添加到persistence.xml后，效果良好：

        value="org.hibernate.transaction.JDBCTransactionFactory" />
