I am trying to connect Cassandra 1.1.9 over Kundera with Play 2.0 framework. I tried the example Getting-Started-in-5-minutes on GitHub. But I got this exception:
[PersistenceLoaderException: com.impetus.kundera.utils.InvalidConfigurationException: Duplicate persistence-units for name: cassandra_pu. verify your persistence.xml file]
I just added kundera-cassandra-2.2.1-jar-with-dependencies.jar to project build path. Should I add anything to application.conf?
