TestNG entityMnager question

[dkane]

Hello
First time using TestNG with Seam components.

Test class :

public class SimpleSearchCase extends SeamTest
{
 EntityManager em;

 @BeforeClass
 public void initEm() throws Exception
 {
 EntityManagerFactory emf =
 Persistence.createEntityManagerFactory("trackUnit");
 em = emf.createEntityManager();
 }
 .....

I am running test from Eclipse .
The project filesystem contains persistence.xml placed relatively in resources/META-INF/

The output :

FAILED CONFIGURATION: @BeforeClass initEm
javax.persistence.PersistenceException: No Persistence provider for EntityManager named trackUnit
 at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:55)
 at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:33)
 at com.avtohouse.test.SimpleSearchCase.initEm(SimpleSearchCase.java:20)
... Removed 22 stack frames
SKIPPED: simpleSearch

How can I point persistence unit to TestNG ?

Thanks

P.S. Ant and seam-gen are not used.

Make sure resources is on the test classpath.

Make sure resources is on the test classpath.

Yes, they are in Run.. , "Classpath" tab here

The same output.

Sorry, didn't read your post carefully. I don't see why you need to init the entity manager in the Java SE fashion if you are using SeamTest.

I need to test Seam component that uses EntityManager. My test is based on "Simplicity and power beyond Java EE" book example :

public class HelloWorldTest extends SeamTest
{

@Test
public void unitTestSayHello() throws Exception
{
 Manager manager = new ManagerAction ();
 EntityManagerFactory emf =
 Persistence.createEntityManagerFactory("helloworld");
 EntityManager em = emf.createEntityManager();
 setField(manager, "em", em);
 Person person = new Person ();
 person.setName ("Thomas Heute");
 setField(manager, "person", person);
 setField(manager, "confirmed", false);

The only difference in my case is initializing EntityManager in @BeforeClass method to use it in different @Test methods then.

What is incorrect ?

Moving that to @Test method does not help, BTW.

Solved by adding hibernate-entitymanager.jar to classpath , thanks to guide :
http://dewarim.de/wms/error/no_persistence_provider_for_entitymanager

It is rather difficut to collect necessary jars for TestNG + Seam, I must say. No documentation found so far.

Now getting

no idea what is still missing

And, the final result for today :)

This is being thrown from line

EntityManagerFactory emf =
 Persistence.createEntityManagerFactory("trackUnit");

Make sure EntityManager and Annotations versions are aligned.

For example, 3.2.1.GA version for both annotatios and entity manager in the jboss maven repository would fix the exception you are getting.
