JPA configuration for play framework

In my current play project we decided to use hibernate as JPA implementation.

Here is the configuration we use:

Dependencies in project/Build.scala

  val appDependencies = Seq(
    javaCore,
    javaJdbc,
    javaJpa,
    "org.hibernate" % "hibernate-entitymanager" % "4.2.7.Final"
  )

Database configuration in conf/application.conf

# Database configuration
# ~~~~~
db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:file:data/db"
db.default.user=sa
db.default.password=""
db.default.jndiName=DefaultDS

jpa.default=defaultPersistenceUnit

Persistence unit in conf/META-INF/persistence.xml

    
        org.hibernate.ejb.HibernatePersistence
        DefaultDS
