Axis2 web service Unknown type problem

[Predrag Ristic]

This is my class where I encapsulate these parameters that I want to send via web service:

    public class GPSInfo implements KvmSerializable {

	private String latitude, longitude, info1, info2, info3;

	public String getLongitude() {
		return longitude;
	}

	public void setLongitude(String longitude) {
		this.longitude = longitude;
	}

	public String getLatitude() {
		return latitude;
	}

	public void setLatitude(String latitude) {
		this.latitude = latitude;
	}

	public String getInfo1() {
		return info1;
	}

	public void setInfo1(String info1) {
		this.info1 = info1;
	}

	public String getInfo2() {
		return info2;
	}

	public void setInfo2(String info2) {
		this.info2 = info2;
	}

	public String getInfo3() {
		return info3;
	}

	public void setInfo3(String info3) {
		this.info3 = info3;
	}

	@Override
	public Object getProperty(int arg0) {
		// TODO Auto-generated method stub

		switch (arg0) {
		case 0:
			return latitude;
		case 1:
			return longitude;
		case 2:
			return info1;
		case 3:
			return info2;
		case 4:
			return info3;
		default:
			break;
		}

		return null;
	}

	@Override
	public int getPropertyCount() {
		// TODO Auto-generated method stub
		return 5;
	}

	@Override
	public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
		// TODO Auto-generated method stub
		switch (arg0) {
		case 0:
			arg2.type = PropertyInfo.STRING_CLASS;
			arg2.name = "latitude";
			break;
		case 1:
			arg2.type = PropertyInfo.STRING_CLASS;
			arg2.name = "longitude";
			break;
		case 2:
			arg2.type = PropertyInfo.STRING_CLASS;
			arg2.name = "info1";
			break;
		case 3:
			arg2.type = PropertyInfo.STRING_CLASS;
			arg2.name = "info2";
			break;
		case 4:
			arg2.type = PropertyInfo.STRING_CLASS;
			arg2.name = "info3";
			break;
		}
	}

	@Override
	public void setProperty(int arg0, Object arg1) {
		// TODO Auto-generated method stub
		switch (arg0) {
		case 0:
			latitude=arg1.toString();
			break;
		case 1:
			longitude=arg1.toString();
			break;
		case 2:
			info1=arg1.toString();
			break;
		case 3:
			info2=arg1.toString();
			break;
		case 4:
			info3=arg1.toString();
			break;
		}
	}

}

and the web service class

    public String writeInfo(GPSInfo info) {
		String out = "success";
		try {
			
			System.out.println("LATITUDE JE:"+info.getLatitude());
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} 
		return out;
	}
	

This is the code in my Android app where I invoke web service:

    String URL = "http://10.0.2.2:9090/GPSInfoWriter/services/GPSInfoWriter.GPSInfoWriterHttpSoap11Endpoint/";
				// String URL =
				// "http://192.168.2.103:9090/TestWS/services/GPSInfoWriter.GPSInfoWriterHttpSoap11Endpoint/";
				String SOAP_ACTION = "writeInfo";
				String METHOD_NAME = "writeInfo";

				SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
				PropertyInfo propertyInfo = new PropertyInfo();
 GPSInfo gpsInfo=new GPSInfo();
				 gpsInfo.setLatitude("14.4343543f");
				 gpsInfo.setLongitude("23.4343543f");
				 gpsInfo.setInfo1("info1");
				 gpsInfo.setInfo2("info2");
				 gpsInfo.setInfo3("info3");
request.addProperty("info",gpsInfo);
				//
				SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
						SoapEnvelope.VER11);
				envelope.setOutputSoapObject(request);
				envelope.addMapping(NAMESPACE, "GPSInfo",
						new GPSInfo().getClass());
//				envelope.addMapping(NAMESPACE,
//				 GPSInfo.class.getSimpleName(),GPSInfo.class);
				 HttpTransportSE androidHttpTransport = new
				 HttpTransportSE(URL);
				//
				 try {
				 androidHttpTransport.debug=true;
				 androidHttpTransport.call(SOAP_ACTION, envelope);
				 SoapObject response = (SoapObject)envelope.getResponse();
				 SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;
				
				 System.out.println();
				
				
				 } catch (Exception e) {
				 e.printStackTrace();
				 System.out.println();
				 }

but I get this response from web server:
[ERROR] Exception occurred while trying to invoke service method writeInfo
org.apache.axis2.AxisFault: Unknow type {http://db.infoterm.com}GPSInfo

Can someone help me with this?Thanks.
