Can't create persistence unit in test class.

[samwun9988]

Hi,

I created ear project for jboss 7.2.

In my junit test class, I can't use Persistence.createEntityManagerFactory to create an entityManager.

This is the junit test class:

public class ProductArticleFacadeTest {

    static EntityManagerFactory emf;

    static EntityManager em;

    public ProductArticleFacadeTest() {

    }

    @BeforeClass

    public static void setUpClass() {

        emf = Persistence.createEntityManagerFactory("TestDatePU");

        em = emf.createEntityManager();

    }

When I execute this file, it failed at emf = Persistence.createEntityManagerFactory("TestDatePU");

Error message is:

caused error: org/hibernate/internal/util/xml/Origin

Here is my persistence.xml file:

<?xml version="1.0" encoding="UTF-8"?>

<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

          <persistence-unit name="TestDatePU" transaction-type="RESOURCE_LOCAL">

                    <properties>

                              <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>

                              <property name="hibernate.hbm2ddl.auto" value="update"/>

                              <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>

                              <property name="hibernate.connection.username" value="root"/>

                              <property name="hibernate.connection.password" value="admin"/>

                        <property name="hibernate.show_sql" value="true"/>

                        <property name="hibernate.format_sql" value="true"/>

                              <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/testdb"/>

                    </properties>

          </persistence-unit>

</persistence>

But it looks like the junit test execution doesn't read this file, therefore it caused the error as I stated in the beginning.

I also attach my project here for reference.

Any suggestion is very much appreciated.

Thanks

Sam
