JPA /Hibernate - model class not found

[Holger Burde]

Hi;

I am quite new to Scala / Play and right now struggling to get JPA working. I think i did all relevant steps:

1 application.conf

....

db.default.jndiName=DefaultDS

jpa.debugSQL=true

jpa.default=PDU1 // name from persistence.xml

...

2 persistence.xml

Name is PDU1 - all model classes (model.xxx) are added to the persistence.xml

location is conf/META-INF/

3 Model classes

Each Model class has a javax.persistence Entity Annotation

Each class is located in controllers.model

Error:

Caused by: javax.persistence.PersistenceException: [PersistenceUnit: PDU1] class or package not found

Caused by: java.lang.ClassNotFoundException: model.ESummary

I am running the current stable release. 

thx in advance

Hi;

Ok i resolved the error by adding javaJpa to Build.scala and now this error pops up:

javax.persistence.PersistenceException: No Persistence provider for EntityManager named true

val appDependencies = Seq(
    // Add your project dependencies here,
    jdbc,
    anorm,
    javaJpa,
    "org.hibernate" % "hibernate-entitymanager" % "4.2.6.Final",
    "org.hibernate" % "hibernate-core" % "4.2.6.Final",
    "mysql" % "mysql-connector-java" % "5.1.26"
  )

persistence.xml
..
  <provider>org.hibernate.ejb.HibernatePersistence</provider>
..

Any idea what this may cause?
