                new StringPart("password", "bbb")
                };
        post.setRequestEntity(new MultipartRequestEntity(parts, post.getParams()));
client.executeMethod(post);
String result = post.getResponseBodyAsString();

HttpClient client = new HttpClient();
PostMethod post = new PostMethod(redirectUrl);
        NameValuePair[] pairs = {
