Hi,
Looks like there might be some confusion. Not sure if MFO is supposed
to be an @Entity bean or a EJB SessionBean (@Stateful, @Stateless,
@Singleton).
There is a slightly different approach you could to take aside from
starting transactions and persisting the Entity right in the test
case. Overall it involves wrapping your EntityManager access with a
session bean. It essentially turns this code:
EntityManager em = null;
try {
em = emf.createEntityManager();
em.getTransaction().begin();
MFO m = new MFO();
m.setName("Hello MFO");
em.persist(m);
assert "success".equals(m.getName());
} catch (Exception e) {
em.getTransaction().rollback();
e.printStackTrace();
} finally {
if (null != em) {
em.close();
}
}
Into this:
@Stateful
public class MyBean implements MyLocal {
@PersistenceContext(unitName = "mfo-unit", type =
PersistenceContextType.EXTENDED)
private EntityManager entityManager;
public void addMFO(MFO mfo) throws Exception {
entityManager.persist(mfo);
}
}
In this setup, the EntityManager will automatically be enrolled in
transactions and when the addMFO method is called a transaction will
automatically be started. Two birds with one stone.
This example shows the basic layout:
http://openejb.apache.org/3.0/injection-of-entitymanager-example.html
You're pretty close, the toplink system properties would be added to
persistence.xml file like this one:
http://svn.apache.org/repos/asf/openejb/tags/openejb-3.1/examples/jpa-eclipselink/src/main/resources/META-INF/persistence.xml
Then in your test case you lookup the Stateful session bean using the
JNDI name printed in the log output (typically beanClass.simpleName()
+ "Local").
In the example there's a "Movie" Entity and a "Movies" Session that is
used to persist/remove/etc. the "Movie" Entities. You don't need to
follow that naming convention. I picked it up the naming convention
from the java.util.Arrays and java.util.Collections classes -- the
plural seems more elegant to me than "Helper" as in ArrayHelper and
CollectionHelper (or "Manager" or "Util"). Just my preference.

Here's my test file.
UserTest.java
public class UserTest {
private EntityManagerFactory emf;
@Test
public void testUser() {
System.out.println("UserTest.testUser: start");
System.out.println("UserTest.testUser: emf is " + (null !=
emf ?
"not null." : "null.") );
EntityManager em = null;
try {
em = emf.createEntityManager();
em.getTransaction().begin();
MFO m = new MFO();
m.setName("Hello MFO");
em.persist(m);
assert "success".equals(m.getName());
} catch (Exception e) {
em.getTransaction().rollback();
e.printStackTrace();
} finally {
if (null != em) {
em.close();
}
}
System.out.println("UserTest.testUser: end");
}
static MFO m;
@BeforeClass
public void init() throws Exception {
System.out.println("UserTest.init: now instantiating
emf. . .");
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.LocalInitialContextFactory");
properties.put("openejbDatasoure",
"new://Resource?type=DataSource");
properties.put("openejbDatasoure.JdbcDriver",

properties.put("openejbDatasoure.JdbcUrl",
"jdbc:mysql://localhost:3306/dost_performers");
properties.put("openejbDatasoure.UserName", "root");
properties.put("openejbDatasoure.Password", "mysql");
System.getProperties().setProperty("toplink.target-server",
"org.apache.openejb.toplink.openejb.OpenEJBTransactionController");
System.getProperties().setProperty("toplink.ddl-generation",
"create-table");
System.getProperties().setProperty("toplink.logging.level",
"INFO");
System.getProperties().setProperty("toplink.create-ddl-jdbc-file-
name",
"create.sql");
System.getProperties().setProperty("toplink.ddl-generation.output-
mode",
"both");
InitialContext initialContext = new InitialContext(properties);
m = (MFO) initialContext.lookup("MFO");
emf =
Persistence.createEntityManagerFactory("ExecutiveSupport4PU");
System.out.println("UserTest.init: emf is " + (null != emf ?
"not
null." : "null.") );
}
@AfterClass
public void destroy() {
System.out.println("UserTest.destroy: now closing emf. . .");
emf.close();
}
}
What should I put in initialContext.lookup()? Name of what?
I would really appreciate for any help.
Thanks :working:
