I have exposed a REST @POST method annotated to produce and consume XML and
JSON. The method parameter and response class is a JAXB object. When called
with wget and an XML request the correct XML responsed is returned. When I
make a wget XML request and ask for a JSON response using the 'accept' http
header I get the correct JSON response returned. My problem is when I use
wget to make a JSON request I get an incorrect response. The JSON request is
not being mapped to the method JAXB object parameter.
I am using Glassfish 3.0.1 and Netbeans 6.9.1 to generate and publish my
war. I enabled logging using the LoggingFilter and can see my JSON request
properly being recieved:

}
I have added a custom JAXB Context Resolver(using natural builder) and see
my logger messages when it is called with each JSON or XML request. My
method is called with an empty JAXB object. The object when marshalled
prints an empty XML payload:
