maven spring JPA configuration on google app engine
From few days I was trying to configure my first app on google app engine(gae) with maven but due to some incompatible version of datanucleus and gae , I was not able to run the application.After spending few couple of days I have finally configured spring ( DI,mvc and Security ) and JPA with maven.I am sharing my configuration so that it will be beneficial for someone.
