Hi Patrik, I too felt it can be because of classpath. But I verified all settings are done and working.
We are using java 1.7 and it is defined in classpath. Also scala version used is 2.11 which is also defined in classpath. Let me know is there any other classpath settings required? Or any specific version of java or scala? - prakhyat m m On Thursday, October 23, 2014, Patrik Nordwall <[email protected]> wrote: > I would guess you have an invalid or incomplete classpath. > /Patrik > > On Wed, Oct 22, 2014 at 9:28 PM, Prakhyat Mallikarjun < > [email protected] > <javascript:_e(%7B%7D,'cvml','[email protected]');>> wrote: > >> Team, >> >> I working on a app built on top of akka persistence and java. >> >> I am using cassandra plugin >> i.e. akka-persistence-cassandra_2.10-0.3.4.jar.
