Java – JBoss as 7 cannot inject resource using @ persistencecontext_ Local container managed entitymanagers

I am using JBoss as 7.1 1, and you can configure a new JTA data source and connect it to my EJB

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

When I try to use resource_ When using local persistenceunit, I receive an error saying that I cannot inject resource using @ persistencecontext_ LOCAL PU.

I have configured persistence XML, as follows:

<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>

And in my Dao,

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


}

When I was in as 7.1 When deploying my application on 1, I received the following error

Use resource for any solution_ Local Pu and @ persistencecontext?

Solution

JTA: in the Java EE environment, transactions are handled by the container & its JTA transactions by default You can get the entity manager by lookup or injection

RESOURCE_ Local: in Java se, the application must explicitly manage transactions & Resource local transactions are local transactions You must create an entitymanagerfactory & then you can create an entity manager from it

When you deploy it in the application server, change the transaction type to persistence JTA. XML
