I call webservice from andriod application, developed using eclipse,
but getting exception when calling
androidHttpTransport.call(SOAP_ACTION, envelope);
ex.getMessage() printing "null" exception message

I had the same problem. I was getting a null exception because i was trying in the main thread. A problem with Honeycomb SDK or higher. http://developer.android.com/reference/android/os/NetworkOnMainThreadException.html
The solution, run the process in a new thread.
Greetings!
You should see this Double with ksoap2 on Android? to add Double property to your soap request in ksoap2.

I am getting no errors in LogCat. The ip showing in code is localhost ip address. I have availability of internet in my AVD.
My MainActivity.java is :

I have added these lines in AndroidManifest.xml
Thanks in advance.
Have you added INTERNET_ACCESS permission to your Manifest?
<manifest xlmns:android...>
...
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>

I am trying to call java webservice form android application but unable to call it. When I generate WSDL file, SOAPAction showing blank
string(<soap:operation soapAction=""/>) in soap:operation.
My android application code:
public class MainActivity extends Activity {
private static final String SOAP_ACTION = "http://com/add";
private static final String METHOD_NAME = "add";
private static final String NAMESPACE = "http://com/";
private static final String URL = "http://localhost:8080/WebApplication1/demo";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button=(Button)findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo pi1 = new PropertyInfo();
pi1.setName("i");
pi1.setValue(3);
pi1.setType(int.class);
request.addProperty(pi1);
PropertyInfo pi2 = new PropertyInfo();
pi2.setName("j");
pi2.setValue(3);
pi2.setType(int.class);
request.addProperty(pi2);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
// HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
try {
((TextView) findViewById(R.id.textView1)).setText(String
.valueOf("The WebService is about to call"));
androidHttpTransport.call(SOAP_ACTION, envelope);
((TextView) findViewById(R.id.textView1)).setText(String
.valueOf("The WebService call is done"));
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
((TextView) findViewById(R.id.textView1)).setText(String
.valueOf(response.toString()));
((TextView) findViewById(R.id.textView1)).setText(String
.valueOf("Done"));
} catch (Exception e) {
e.printStackTrace();
Log.e("Err", "Error Says: " + e.toString());
}
}
});
}
}
There is showing an exception network on main thread exception
Because you are calling the web service in your main thread.This must be done in the background using background thread.You can use asyntask for background operations.
I am new to android. In my application I tried to call SOAP web services, in that I can't understand what is meant
for(SOAP_Action,OperationName,WSDL_TARGET_NAMESPACE,SOAP_ADDRESS). The following is my full code
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
TextView textView = new TextView(this);
setContentView(textView);
SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
OPERATION_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
System.out.println("subbu="+request);
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
try
{
httpTransport.call(SOAP_ACTION, envelope);
Object response = envelope.getResponse();
textView.setText(response.toString());
}
catch (Exception exception)
{
textView.setText(exception.toString());
}
}
}
Can anybody explain what thats purpose for. Give some link from which I can get idea.
SOAP_ACTION / NAMESPACE and METHODS can be found in the WSDL file of the target webservice !
Here is a sample code to send a SOAP request to a webservice :
public class SoapRequest {
private static final String SOAP_ACTION = "xxx";
private static final String METHOD_NAME = "xxx";
private static final String NAMESPACE = "xxx";
private static final String URL = "url of the webservice";
public static SoapObject soap() throws IOException, XmlPullParserException {
SoapObject request = new SoapObject (NAMESPACE, METHOD_NAME);
/* Here you can add properties to your requests */
PropertyInfo pi1 = new PropertyInfo();
pi1.name = "xxx";
pi1.type = String.class;
request.addProperty(pi1, "xxx");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject soapResult = (SoapObject) envelope.bodyIn;
return soapResult;
}
I am having some issues with accessing a web service. Getting ClassCastException Error. Consider a scenario that I am trying to access a method of a web-service and the webservice is supposed to return two strings (Lets say String1 and String2). Moreover, I have to provide or pass two parameters (lets say Parameter 1 and Parameter 2 where Parameter 1 should be integer and Parameter 2 should be String) Here is my code
public class MyWebService extends Activity {
private static final String SOAP_ACTION ="http://www.mywebsite.com/myMethod";
private static final String METHOD_NAME = "MyMethod";
private static final String NAMESPACE = "http://www.myNamespace/";
private static final String URL = "http://mysession.com/myservice.asmx?WSDL";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo pi = new PropertyInfo();
pi.setName("Parameter 1");
pi.setValue(1);
pi.setType(pi.INTEGER_CLASS);
request.addProperty(pi);
PropertyInfo pi2 = new PropertyInfo();
pi2.setName("Parameter 2");
pi2.setValue("Any string");
pi2.setType(pi2.STRING_CLASS);
request.addProperty(pi2);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject result=(SoapObject)envelope.getResponse();
String string1=result.getProperty(0).toString();
String string2=result.getProperty(1).toString();
} catch (Exception e) {
e.printStackTrace();
}
}
}
This is the exception I am getting
java.lang.ClassCastException: org.ksoap2.serialization.SoapPrimitive
Can anyone tell me if I am doing something wrong here..
Thanks
Try this,
SoapPrimitive result= (SoapPrimitive)envelope.getResponse();
OR
Object result= (Object)envelope.getResponse();
instead of
SoapObject result=(SoapObject)envelope.getResponse();
Try this:
SoapObject request = new SoapObject(SOAP_NAMESPACE,SOAP_METHOD);
request.addProperty("name", abcd);
request.addProperty("age", 30);
I can call a webservice with KSOAP2 from android,now i want to know is it possible to call it without using KSOAP.If anyone knows the answer please help me.
If the webservice is available with a rest api I would use Restlet. I have some blog posts that show simple examples of using this library here.
public class SOAPActivity extends Activity {
private final String NAMESPACE = "http://www.webserviceX.NET/";
private final String URL = "http://www.webservicex.net/ConvertWeight.asmx";
private final String SOAP_ACTION = "http://www.webserviceX.NET/ConvertWeight";
private final String METHOD_NAME = "ConvertWeight";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SoapObject soapObject=new SoapObject(NAMESPACE, METHOD_NAME);
String weight = "700";
String fromUnit = "Kilograms";
String toUnit = "Grams";
PropertyInfo weightProp =new PropertyInfo();
weightProp.setName("Weight");
weightProp.setValue(weight);
weightProp.setType(double.class);
soapObject.addProperty(weightProp);
PropertyInfo fromProp =new PropertyInfo();
fromProp.setName("FromUnit");
fromProp.setValue(fromUnit);
fromProp.setType(String.class);
soapObject.addProperty(fromProp);
PropertyInfo toProp =new PropertyInfo();
toProp.setName("ToUnit");
toProp.setValue(toUnit);
toProp.setType(String.class);
soapObject.addProperty(toProp);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(soapObject);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
Log.i("myApp", response.toString());
TextView tv = new TextView(this);
tv.setText(weight+" "+fromUnit+" equal "+response.toString()+ " "+toUnit);
setContentView(tv);
} catch (Exception e) {
e.printStackTrace();
}
}
}
This is simple code for SOAP web service,
