For testing purpose I am trying to make a JPA connection to our database.
I get an error saying:
Unable to configure EntityManagerFactory
with no further explanation!
I think I have tried everything in my persistence file and now finally I give up.
My persistence.xml (only the persistence-unit):
<persistence-unit name="Test" transaction-type="RESOURCE_LOCAL">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <class>dme.dm.device.Operation</class>
| <class>dme.dm.device.Action</class>
| <properties>
| <property name="hibernate.connection.driver_class"
| value="com.mysql.jdbc.Driver"/>
| <property name="hibernate.connection.username"
| value="jboss"/>
| <property name="hibernate.connection.password"
| value="banan123"/>
| <property name="hibernate.connection.url"
| value="jdbc:mysql://172.16.12.15/dm_tos"/>
| <property name="hibernate.dialect"
| value="org.hibernate.dialect.MySQLDialect"/>
| <property name="hibernate.hbm2ddl.auto"
| value="update"/>
| </properties>
| </persistence-unit>
And I make the call like this:
public class OperationTest {
| private EntityManager entityManager;
|
| @Before
| public void setUp() {
| EntityManagerFactory emf = Persistence.createEntityManagerFactory("Test");
| entityManager = emf.createEntityManager();
| }
| }
When I run this code I get the exception:
javax.persistence.PersistenceException: [PersistenceUnit: Test] Unable to configure EntityManagerFactory
Does anyone have an idea of what could be wrong?
Regards,
Thomas
