I found how to populate the POSTBody request from a json string
using ObjectMapper:

import com.fasterxml.jackson.databind.ObjectMapper;
        SubmitPOSTBody body;
    	String json = json();
        ObjectMapper mapper = new ObjectMapper();
        try {
        	body = mapper.readValue(json, SubmitPOSTBody.class);
                Response<SubmitPOSTResponseBody> result = 
                	Client.create().application.submit.post(body());
