Hi,
JAX-RS/Jersey does not support the serialization of primitive types
(or their Object counter parts).
If you want to support such types you need to implement your own
message body writer and also declare an appropriate media type with
that writer (the content-type of the response will use that, if
@Produces does not declare it).
IMHO application/octet-stream is not appropriate for such content, as
it is most likely you will serialize the boolean value out as the
strings "true" or "false". I would recommend using text/plain and
document the representation. You can always use String in your
resource method as well.
Part of the issue with returning such primitive data is there are,
AFAIK, no specific media types associated with them.
