I havent worked with Jackson but I am guessing the issue is the Business class is a member class and not static.
I wanted to accept an answer that someone posted before because it led me in the right direction. I made every member class static (and later had to add @JsonIgnoreProperties(ignoreUnknown = true) to one of them) and it works.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
