As I in tune with the Marshaller and Unmarshaller used in your example, Would you mind explaining how this could work with assorted data types (disclose, A JSON blob or a chain array)?If you can use the default Jersey/JAXB marshalling into XML, You would build a schema reflecting the structure you have indicated that includes collections (Unbounded essentials) And reach (running xjc) the related java classes. The response from your restful service would be the type for this }
