JndiEMF

class JndiEMF extends ScalaEMFactory

This class represents an EntityManager factory that is retrieved from JNDI, using JTA to handle transactions. An example of usage would be:

object FooEM extends JndiEMF("java:/myEM")

...

def doSomething = {
  val em = FooEM.newEM
  ...
  em.close()
}
