Connect to Cassandra DB within Play framework by using Kundera

Question

I tried using Kundera method but I have no idea where to put the persistence.xml, i tried putting it in conf/WEB-INF/ but when I tried running it said that "Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named cassandra_pu".

Can somebody show mw where i were wrong? Is there any other way to connect Cassandra to Play 2.0.4?
Thank you very much

Answer 2

For Kundera the persistence.xml should typically be in $PROJECT_ROOT/src/META-INF/persistence.xml

Answer 3

Another option is PlayOrm for cassandra is nearly done with it's playframework plugin. Still need to do a playframework module AND it has the in-memory version as well for rapid development. It should be done by the end of next week.

Documentation on playorm with playframework can be found here
