I want to send this as XML to my Web Service. How should I do that?
<dmi:ShipNoticeRequest xmlns:dmi="http://portal.suppliesnet.net">
<dmi:RequesterISA>xxxxxxxxxx</dmi:RequesterISA>
<dmi:ShipDateRange>
<dmi:ShipDateFrom>2009-09-09</dmi: ShipDateFrom>
<dmi:ShipDateTo>2009-09-10</dmi: ShipDateTo>
</dmi: ShipDateRange >
</dmi:ShipNoticeRequest>
My Web Service method required this type of request message:
POST /ShipNotice/WebServiceShipNotice.asmx HTTP/1.1
Host: portal.suppliesnet.net
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://portal.suppliesnet.net/RequestShipmentNoticeXML"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<RequestShipmentNoticeXML xmlns="http://portal.suppliesnet.net">
<ShipNoticeRequestNode>xml</ShipNoticeRequestNode>
</RequestShipmentNoticeXML>
</soap:Body>
</soap:Envelope>
I am tring this method but geeting an unknown error Can you figure out what is wrong with this code?

回答1:
You want to send SOAP msg and Android don't have direct support for sending those kind of messages. There are 3rd party libraries like KSOAP2-android which you can try.
How should each SOAP msg look like is given by WSDL file on server side. Try to find it on the server and look how each msg should look. You can use soapUI to parse WSDL file for you.
If you don't use any 3rd party library as mentioned above you have to compose that msg by your self. You will need to create some sort of HTTP client like this:
HttpURLConnection conn = null;
conn = (HttpURLConnection) new URL(url).openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "text/xml");
conn.setRequestProperty("Content-Length", "" + postMessageInBytes.length);
Body of request will be created using for example XmlSerializer which will help you to write needed tags etc.

You can use KSOAP2 to access web service, and your XML data can easily be sent as String...
1.Download the ksoap2 jar file
2.Start eclipse and create new android project
3.Right click on your project
4.Click properties
5.Click the java build path from the left pane
6.Select library tab
7.Click on add external jar
8.Browse the downloaded jar file
Your activity should look like this...
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.*;
import android.util.Log;
import android.widget.TextView;
import android.os.Bundle;
public class FinalWebServiceDemoActivity extends Activity {
// some parameters regarding your web-service to be invoked
private static final String SOAP_ACTION = "http://tempuri.org/WebServiceMethod";
private static final String METHOD_NAME = "WebServiceMethod";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://10.0.2.2:2256/WebService.asmx";
TextView tv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv=(TextView)findViewById(R.id.text1);
call();
}
public void call()
{
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("message","Put your XML data here...");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
String strRes = result.toString();
tv.setText(strRes);
} catch (Exception e) {
tv.setText("Exception...");
Log.i("exception", e.toString());
StackTraceElement elements[] = e.getStackTrace();
for (int i = 0, n = elements.length; i < n; i++) {
Log.i("File", elements[i].getFileName());
Log.i("Line", String.valueOf(elements[i].getLineNumber()));
Log.i("Method", elements[i].getMethodName());
}
}
}
}
Don't forget to add <uses-permission android:name="android.permission.INTERNET" /> permission in manifest file.
NOTE: This code is written to access .NET Web Services running on local machine and IPs are to access is form Android Emulator. Modify it where necessary.
Hope this helps...

Try this (pure Java Standard):
private WebServiceConnection(String xmlString) {
InputStream responseInputStream = null;
OutputStream requestOutputStream = null;
HttpURLConnection httpURLConnection = null;
try {
// Form the URL
URL url = new URL(URL_BASE + "?serviceId=3");
// Set the HTTP URL connection
httpURLConnection = (HttpURLConnection)url.openConnection();
httpURLConnection.setDoOutput(true);
httpURLConnection.setConnectTimeout(15000);
httpURLConnection.setRequestProperty("Accept-Charset", "UTF-8");
httpURLConnection.setRequestProperty("Content-Type", "text/html");
// Send request
requestOutputStream = httpURLConnection.getOutputStream();
requestOutputStream.write(xmlString.getBytes("UTF-8"));
// Receive response, then do anything with it
responseInputStream = httpURLConnection.getInputStream();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch(SocketTimeoutException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
