Hi peter, I am tryn to use jo4neo with playframework.... firstly, im unable to resolve it as a dependency directly from maven,
secondly, with my manually downloaded lib from http://jo4neo.googlecode.com/svn/trunk/repo/thewebsemantic/jo4neo/0.4.1/ and noe4j from maven, when i try to run my application is it the error i get: Internal Server Error (500) for request GET /Rendezvous/index Oops: NoClassDefFoundError An unexpected error occured caused by exception NoClassDefFoundError: org/neo4j/index/IndexService play.exceptions.UnexpectedException: Unexpected Error at play.mvc.ActionInvoker.invoke(ActionInvoker.java:255) at Invocation.HTTP Request(Play!)
