public class SimpleHttpPut { 
  public static void main(String[] args) {
    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost("http://http://localhost:8089/CustomerChatSwing/JoinAction");
    try {
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
      nameValuePairs.add(new BasicNameValuePair("userId",
      "123456789"));
      post.setEntity(new UrlEncodedFormEntity(nameValuePairs));

      HttpResponse response = client.execute(post);
      BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
      String line = "";
      while ((line = rd.readLine()) != null) {
    System.out.println(line);
      }

    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

You can use HttpPost， there are methods to add Header to the Request.

DefaultHttpClient httpclient = new DefaultHttpClient();
String url = "http://localhost";
HttpPost httpPost = new HttpPost(url);

httpPost.addHeader("header-name" , "header-value");

HttpResponse response = httpclient.execute(httpPost);
