as cans ee using tilesviewresolver; viewresolver tries respond in html; suggest use org.springframework.web.servlet.view.contentnegotiatingviewresolver (an article available here spring contentnegotingviewresolver
basically point spring tries respond in html since using tilesviewresolver; need, instead, json response in "mix" kind of response, contentnegotiatingviewresolver can you
