Hard to be sure from what you've described, but it looks as though the
entity doesn't contain anything. Try getting the raw contents of the entity
in two places (1) before you post it and and (2) after you receive it but
before you parse it by passing it to the JacksonRepresentation constructor.
Does it look like valid JSON in both cases?
