Here's my item.java class

@Table(name = "BoTestItemMain", schema = "cision@hbaseTest")

public class Item {

Here's the Exception

[debug] c.i.k.p.EntityManagerImpl - Created EntityManager for persistence unit : hbaseTest

Any CRUD operation on this entity will fail.If your entity is for RDBMS, make sure you put fully qualified entity class name under <class></class> tag in persistence.xml for RDBMS persistence unit. Returning null value.

[error] application -

I'm not sure if it's Play that's not playing nice or an issue with Kundera.

Few questions, in case of war deployment:

1. your entity classes are under WEB-INF/classes, in case of war deployment?

2. persistence.xml is under WEB-INF/META-INF/persistence.xml?

Also, Could you please share bit more on error logs?

I'm using Play Framework.

/conf

/META-INF

/persistence.xml

Here's the code

/// Post

Object o = request().body().asJson();

Item item = (Item) BaseApiController.mapper.readValue(o.toString(), Item.class);

emf = Persistence.createEntityManagerFactory("hbaseTest");

em = emf.createEntityManager();

em.persist(item);

em.close();

emf.close();
