My code:

public static String startVacationRequestProcess(String processDefinitionId) throws Exception {
        String uri = "http://localhost:8080/activiti-rest/service/runtime/process-instances";
        JSONStringer jsRequest = new JSONStringer();
        jsRequest.object();
        jsRequest.key("processDefinitionId").value(processDefinitionId);
        jsRequest.key("employeeName").value("Miss Piggy");
        jsRequest.key("numberOfDays").value("10");
        jsRequest.key("startDate").value("2011-01-01");
        jsRequest.key("returnDate").value("2011-01-11");
        jsRequest.key("vacationMotivation").value("tired");
        jsRequest.endObject();
        Representation rep = new JsonRepresentation(jsRequest);
        JSONObject jsObj = new JSONObject(getClientResource(uri).post(rep).getText());
        logger.info("Returning processId " + jsObj.getString("id"));
        return jsObj.getString("id");
    }
