persistence.xml With SBT Project

[bryaan]

I placed the persistence.xml file in history/src/main/resources/META-INF/ yet I am still getting an error.

Where should I be putting the XML file, and what should I change with SBT?

SBT:

lazy val history = (project in file("history"))
  .settings(
    libraryDependencies += "com.impetus.kundera.client" % "kundera-cassandra" % "2.17"
  )

Some Scala Code: (Java Conversion is Straightforward)

object Test {
  def main(args: Array[String]) {

    new HistoryCore()

  }
}

class HistoryCore {

  val emf: EntityManagerFactory = Persistence.createEntityManagerFactory("cassandra_pu")

  val em: EntityManager = emf.createEntityManager()
  em.persist(TradeData(DateTime.now(), 1.618))
  em.close()
  emf.close()

  // @BeanProperty dynamically adds a getter and a setter for the given variable. This keeps the code clean and the JPA implementation working
  @Entity
  @Table(name = "users", schema = "KunderaExamples@cassandra_pu")
  case class TradeData(@Id
                       @BeanProperty
                       var time: DateTime,
                       @Column(name = "price")
                       @BeanProperty
                       var price: Double)
}

Error:

We are looking into the issue and will get back to you.

@futurehorizon Bottomline is, persistence.xml has to be on classpath as META-INF/persistence.xml

Not sure, but please see if https://github.com/knoldus/playing-kundera-cassandra helps you!

Hi @bryaan

I have a Play! Java project that I'm building with SBT and the Play! recomendations is to put the persistence.xml in the conf/META-INF dir. The build process copies this folder to the target dir and adds it to classpath when running the application. So I figure it's a classpath problem. Please check if the resources folder is being included in the classpath of your application when running.
