The following controller is working because I can single step thru it:

I use this command line:


However, I get this error from curl:


OK, so what do I have to do to fix this? Somewhere it needs to know how to generate JSON and it is not doing it.
Can someone guide me?
Thanks

Have you tried adding produces = "application/json" to your RequestMapping annotation?

OK, I tried your suggestion:


I'm still getting

"The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers."

Have a check on this line and its implication.
To me, the server is saying I'm expecting a header tag Content-Type=text/xml or application/json.

Did the client send a header tag

Content-type: text/xml or application/json
