java - JSON output of a JAX-WS webservice?

Question

Is it possible that a jax-ws soap-webservice can output json format instead of xml?

@Component
@WebService
public class HRSService {

    @WebMethod
    public String test(String value) {
        return value; //returned as XML. JSON possible?
    }
}

Answer 1

Apparently it's possible by following the instructions indicated at https://jax-ws-commons.java.net/json/ (Archive version)

Summing up:

@BindingType(JSONBindingID.JSON_BINDING)
public class MyService {

    public Book get(@WebParam(name="id") int id) {
        Book b = new Book();
        b.id = id;
        return b;
    }

    public static final class Book {
        public int id = 1;
        public String title = "Java";
    }
}

You just need jaxws-json.jar in your WEB-INF/lib for this to work.

I hope it helps!
