> I am getting below exception and not able to figure out what is wrong with
> the code.
> I have simplified my pojo classes which are to be persisted to ignite cache,
> but still the complexity remains.
> All my pojos are serializable but few of them have business logic code, dao,
> application context object. These objects can't be removed. Removing these
> things from the code will require whole code refractoring.
