URL: It is the url of WSDL file.

NAMESPACE: The targetNamespace in WSDL.

METHOD_NAME: It is the method name in web service. We can have several methods.


You can obtain above details by reading WSDL file of web service.

The soap web service that I have used in this example have only one method that takes a number as parameter and find its square.

How to call soap web service?

  • First create request object of SoapObject class.
  • Now add information to request object that you want to send to web service. This is done using PropertyInfo class.
  • Create soap envelope using SoapSerializationEnvelope class.
  • Assign request object to envelope using setOutputSoapObject().
  • Create object of HttpTransportSE() class. Using this object call the soap web service.
  • We can get response from web service by using getResponse() method of SoapSerializationEnvelope class. The response is stored into SoapPrimitive reference variable.

This is how we use ksop2 library to call soap web service in android.
