Denis Magda commented on IGNITE-1255:
-------------------------------------

Yeah, you have to put {{com.doctor.ignite.example.Person}} class on every node.

As for {{peerClassLoadingEnabled}} property it works only in conjunction with compute engine tasks' classes.
You can ready more on this here: http://apacheignite.gridgain.org/v1.0/docs/zero-deployment

Probably it's time to better clarify {{peerClassLoadingEnabled}} scope because many developers are getting confused with it.
