This is siva, I am newly learning playframe work , I am trying to connect
play 2.0 project with mySQL database by using hibernate(JPA). Still I
didn't get solution. Could you tell exact steps for that configuration or
could you share that project to me.

Still a similar problem even after doing all below. I found some older JBoss posts mentioning old JDK version. Mine is on Mac.
$ java -version java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)
Any suggestions?

PersistenceException: [PersistenceUnit: defaultPersistenceUnit] Unable to build EntityManagerFactory No source available, here is the exception stack trace:
->javax.persistence.PersistenceException: [PersistenceUnit: defaultPersistenceUnit] Unable to build EntityManagerFactory
I think that is better look at the stack trace in your console. Maybe there
is more information there. Also, could you give us more details about how
are you configuring your app to use jpa?

We have selected play2.1, scala 2.1.0 and hibernate for a large enterprise product's backend REST services development. Can you please suggest if we have choosen the right technologies? about using Scala and Hibernate, and also can you please show a good sample configuration for Play2.1, Scala 2.1.0 and Hibernate, MySQL project.

Hi, I have created a basic sample for the configuration of Play 2.1.1 Framework, Scala 2.10 Language, Spring3 for dependency injection and Hibernate4 as ORM.
Although the dependency "*javaJpa*" was in the "*Build.scala*" file, i wasn't able to use the *play.db.jpa.JPA* helper, so i tried to follow the j2ee 6 official tutorial (
http://docs.oracle.com/javaee/6/tutorial/doc/bnbpy.html).
Following the tutorial those problems occurred.
All the examples are using the JPA helper, so i needed to use too. So i cleaned the project, forced the application to update the dependencies (using *play update*) and then i was able to use the JPA helper.
Using the helper those errors disappeared.
Clean the project, force the update of the dependencies and use the JPA helper!
In the worst case clean the sbt dependencies or create a new play installation folder.
Now i've got others, but it's my fault!
I hope it helps!
