отправка списка / карты в виде джерси параметра POST

Я хочу отправить объект HashMap на ресурс ReST как переменную POST. Я использовал класс Form для отправки объекта. Код клиента:

public static void main(String[] args)
    {
        ClientConfig config = new DefaultClientConfig();
        Client client = Client.create(config);
        WebResource service = client.resource(getBaseURI());

        HashMap<String, String> hashmap = new HashMap<String, String>();
        hashmap.put("Key1", "value1");
        hashmap.put("Key2", "value2");
        Form form = new Form();

        form.add("data1", hashmap);

        ClientResponse response = service.path("hello2").path("hello2").type(MediaType.APPLICATION_FORM_URLENCODED).post(ClientResponse.class, form);
        @SuppressWarnings("unchecked")
        MultivaluedMap<String, String> map = response.getEntity(MultivaluedMap.class);
        System.out.println(map.get("response").get(0));
        System.out.println(map.get("response2"));
    }

Ресурс REST выглядит следующим образом:

@Path("/hello2")
public class FormResource
{
    @Context
    UriInfo uriInfo;
    @Context
    Request request;

    public FormResource()
    {
    }

    public FormResource(UriInfo uriInfo, Request request)// , String data1)
    {
        this.uriInfo = uriInfo;
        this.request = request;
    }

    @POST
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public MultivaluedMap<String, String> newProj(@FormParam("data1") HashMap<String, String> postVarMap, @Context HttpServletResponse response)
    {

        System.out.println(postVarMap);
        MultivaluedMap<String, String> hash = new MultivaluedMapImpl();
        hash.add("response", "response1");
        hash.add("response", "response2");
        hash.add("response2", "fbshabfsdb");
        URI uri = uriInfo.getAbsolutePathBuilder().build();
        Response.created(uri).build();
        return hash;
    }

}

Я получаю следующее исключение в журнале Tomcat 6.0

Правильно ли написан мной код клиента? Есть ли другой способ отправить объект HashMap как переменную POST?
