Я пытаюсь создать веб-приложение, используя Hibernate, Red Hat JBoss-EAP 7.1. В своем коде я создаю экземпляр EntityManager, как этот (в классе MessageDaoImpl, который):
public class MessageDaoImpl implements MessageDao {
private EntityManager em;
public MessageDaoImpl() {
em = Persistence.createEntityManagerFactory("primary").createEntityManager();
}
}
Вот мой persistance. xml file
<persistence version="2.1"
xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://xmlns.jcp.org/xml/ns/persistence
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="primary">
<jta-data-source>java:/datasources/myDS-ds</jta-data-source>
<properties>
<!-- Properties for Hibernate -->
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="hibernate.show_sql" value="false" />
</properties>
</persistence-unit>
</persistence>
И я могу найти свой источник данных здесь:
Когда я подключился, я получил это stackError:

Кто-нибудь знает, как я могу создать экземпляр моего entityManager?
