hi everyone:
i write a simple jpa demo,still hava two bugs.
(i use jboss as 7.1.1.final ; jdk1.7)
1,follow deltaspike jpamodule documents,i define a EntityManagerProducer
public class EntityManagerProducer
{
@PersistenceContext(unitName = "persistence0")
private EntityManager entityManager;
@Produces
@RequestScoped
protected EntityManager createEntityManager()
{
return this.entityManager;
}
protected void closeEntityManager(@Disposes EntityManager entityManager)
{
if (entityManager.isOpen())
{
entityManager.close();
}
}
}
2,and i want do some database action:
---------------------------
@Named("jpaTest")
public class JpaTest
{
@Inject
private EntityManager entityManager;
@Named
@Transactional
public void executeInTransaction(){
Query query = null;
String sql="insert into grandscape_user (user_name,user_password)
values (:u,:p)";
query=entityManager.createNativeQuery(sql);
query.setParameter("u", "2013");
query.setParameter("p", "20132222");
query.executeUpdate();
}
}
-------------------
3,i use jsf to call method #{jpaTest.executeInTransaction}.
<h:commandButton value="jpa Method" action="#{jpaTest.executeInTransaction}" />
4,and persistence.xml.
if transaction-type="JTA" ,the code run to [A JTA EntityManager cannot use
getTransaction] error.
(BUG1)
i add the alternatives section to beans.xml to fix.
<beans xmlns="http://java.sun.com/xml/ns/javaee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/beans_1_0.xsd";>
<interceptors>
<class>org.apache.deltaspike.security.impl.extension.SecurityInterceptor</class>
<class>org.apache.deltaspike.jpa.impl.transaction.TransactionalInterceptor</class>
</interceptors>
<alternatives>
<class>org.apache.deltaspike.jpa.impl.transaction.BeanManagedUserTransactionStrategy</class>
</alternatives>
</beans>
but the code still run to error(A JTA EntityManager cannot use getTransaction())
so i set transaction-type="RESOURCE_LOCAL".
---------------------
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence";

version="2.0">
<persistence-unit name="persistence0" transaction-type="RESOURCE_LOCAL">

<!--

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

5,finally,when i called #{jpaTest.executeInTransaction} method,the data was
fill to database successful,
but the code run to a error:
(BUG2)

disappeared.
