Question

Upon trying to get my response in JSON using Spring 3.x, I get the 406 error \"The resource identified by this request is only capable

Answer 1

I had similar issue but it was weird. I will explain how I resolved it.

In my web.xml my dispacher servlet was mapped to *.htm

    mvc-dispatcher
    /

and no matter what I did it always threw -

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

Finally I changed it to

    mvc-dispatcher
    /

and it worked. What I think is when you just specify

I would also like to add that produces annotation that you, spring will try to map it will accept header of the incoming request. I was making request handler method generic for json and xml. Since I am using Java 8 and Jaxb is inbuilt in Java since Java 7 no need for JAXB dependency. For json I only needed to add -

I am using ivy for dependency management.
