Re: [Resteasy-users] How to use JSON message body in POST

Hi,
Sorry for the so late reply. We've moved the mailing list to user jboss 
mailing list: http://resteasy.jboss.org/mailinglists from May 2016.
Did you try with add @Body annotation in TestData class and directly use 
the annotated filed in your service ? If @Body is not a required thing 
to use , can you simply try with the
latest resteasy and directly send the json request which represents the 
TestData object ? I can't see why @Body is required here.

Cheers,
Jim
