How to send HTTP POST request and receive response?

I'm going to create mobile application that works with CommuniGate Pro server.

For example, I need to make the following Android Client C - CGP Server S conversation and get XIMSS.nonce node value:

C:GET /ximsslogin/ HTTP/1.1
  Host: myserver.com
  Content-Type: text/xml
  Content-Length: 42

  <XIMSS><listFeatures id="list" /><XIMSS>

S:HTTP/1.1 200 OK
  Content-Length: 231
  Connection: keep-alive
  Content-Type: text/xml;charset=utf-8
  Server: CommuniGatePro/5.3

  <XIMSS><nonce>2C3E575E5498CE63574D40F18D00C873</nonce><language>german</language><response id="s"/></XIMSS>

Example, in ActionScript 3.0 it looks this way:

var loader:Loader = new Loader();
loader.addEventListener(Event.COMPLETE, completeHandler);
var urlRequest:URLRequest = new URLRequest(...);
urlRequest.method = ...;
urlRequest.data = ...;
loader.load(urlRequest);

private function completeHandler(...):void { ... };

How will it look in Java for Android 2.1?

As Schnapple says your question seems very broad and is confusing to read and understand.

Here is some general code to send a HTTP POST and get a response from a server though that may be helpful.

public String postPage(String url, File data, boolean returnAddr) {

    ret = null;

    httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2109);

    httpPost = new HttpPost(url);
    response = null;

    FileEntity tmp = null;       

    tmp = new FileEntity(data,"UTF-8");

    httpPost.setEntity(tmp);

    try {
        response = httpClient.execute(httpPost,localContext);
    } catch (ClientProtocolException e) {
        System.out.println("HTTPHelp : ClientProtocolException : "+e);
    } catch (IOException e) {
        System.out.println("HTTPHelp : IOException : "+e);
    } 
            ret = response.getStatusLine().toString();

            return ret;
}
