java – JBoss AS 7无法使用@PersistenceContext注入RESOURCE_LO

@PersistenceContext(unitName="TestPU")
private EntityManager entityManager;

当我尝试使用RESOURCE_LOCAL PersistenceUnit时,我收到错误,说我无法使用@PersistenceContext注入RESOURCE_LOCAL PU.

我已经配置了persistence.xml,如下所示：

<persistence-unit name="TestPU" transaction-type="RESOURCE_LOCAL">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>
      <properties>   
    <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/xy"/>
        <property name="javax.persistence.jdbc.user" value="root"/>
        <property name="javax.persistence.jdbc.password" value="blah"/>        
        <property name="hibernate.hbm2ddl.auto" value="update" />       
      </properties> 
</persistence-unit>

而在我的DAO中,

@Stateless
public class UserDAO {
    @PersistenceContext(unitName="TestPU")
    private EntityManager entityManager;


}

当我在AS 7.1.1上部署我的应用程序时,我收到以下错误.

JBAS011428: Cannot inject RESOURCE_LOCAL container managed EntityManagers using @PersistenceContext

任何解决方案使用RESOURCE_LOCAL PU与@PersistenceContext？
