How to create node with service3.0

I am try to save a node with service3.0, but it didn't worked,
I am using restful style, is there any example to save a node using service3?

public Object nodeSave(MultivaluedMap<String, String> queryParams) {

    Client client = Client.create();
    WebResource webResource = client
            .resource("http://localhost/drupal/rest/node/create?XDEBUG_SESSION_START=ECLIPSE_DBGP&KEY=13033148613441");

    Cookie cookie = getCookie();
    ClientResponse response = webResource.accept("application/json").cookie(cookie).put(ClientResponse.class, queryParams);
    int status = response.getStatus();

    String textEntity = response.getEntity(String.class);
    System.out.println(textEntity);

    if (Response.Status.OK.getStatusCode() == status) {
         textEntity = response.getEntity(String.class);
        System.out.println(textEntity);

    }

    return null;
}
