POST JSON fails with 415 Unsupported media type, Spring 3 mvc

Question

I am trying to send a POST request to a servlet. Request is sent via jQuery in this way:

var productCategory = new Object();
productCategory.idProductCategor         


        

Answer 1

I had the same issue. adding

<mvc:annotation-driven />
<mvc:default-servlet-handler />

to the spring-xml solved it

Answer 2

I had a similar problem but found the issue was that I had neglected to provide a default constructor for the DTO that was annotated with @RequestBody.
