public class MarshallingView
Spring-MVC View that allows for response context to be rendered as the result of marshalling by a Marshaller.
The Object to be marshalled is supplied as a parameter in the model and then detected during response rendering. Users can either specify a specific entry in the
model via the sourceKey property or have Spring locate the Source object.

MarshallingView with no Marshaller set. The marshaller must be set after
construction by invoking setMarshaller(Marshaller).
public MarshallingView(Marshaller marshaller)
MarshallingView with the given Marshaller set.

AbstractViewThe first step will be preparing the request: In the JSP case, this would mean setting model objects as request attributes. The second step will be the actual rendering of the view, for example including the JSP via a RequestDispatcher.
