Severe: MessageBodyWriter not found for media type=application/json


I'm just starting out with Java and I'm trying to build a simple API.

The issue I'm having is that I'm getting this message when trying to return an Object as JSON.

Severe:   MessageBodyWriter not found for media type=application/json

I've setup the application with Maven, and as a result of some research I've added the following dependancies to the pom.xml file in the hope that it would resolve the issue.


Open in new window

The method I have which is trying to return the Object as JSON is as follows;
    public Person getAll() {
        Person me = new Person("John", "Doe", "");
        return me;

Open in new window

Can anyone see where I'm going wrong? Do I need to add anything to the web.xml file to make it work?java
