how to set soap Header using ksoap2 - android

Question

I need to set the soap header information as part of authentication of a web method. I'm using ksoap2 API to call .NET web service. Here is the soap header with request.

<soap:Header>
    <DTHeader xmlns="http://myServer.com/webservices/">
      <Username> string </Username>
      <Password> string </Password>
    </DTHeader>
</soap:Header>
<soap:Body>
    <MyTestMethod xmlns="http://myServer.com/webservices/">
       <ID> string </ID>
       <TransID> guid </TransID>
     </MyTestMethod>
</soap:Body>

Can you please provide the android code to set the soap header "DTHeader" and set "Username" and "Password".

I did that this way:

import org.kxml2.kdom.Element;

then while preparing envelope

soapEnvelope.headerOut = new Element[1];
soapEnvelope.headerOut[0] = buildAuthHeader();
// ...send request...

with

private Element buildAuthHeader() {
    Element h = new Element().createElement(NAMESPACE, "AuthHeader");
    Element username = new Element().createElement(NAMESPACE, "user");
    username.addChild(Node.TEXT, USERNAME);
    h.addChild(Node.ELEMENT, username);
    Element pass = new Element().createElement(NAMESPACE, "pass");
    pass.addChild(Node.TEXT, PASSWORD);
    h.addChild(Node.ELEMENT, pass);

    return h;
}

obviously, change strings as needed.

Thanks for the quick response. Now I'm able to add soap header as part of soap request. But have one other problem. As part of the Web Method call, I have two parameters to be passed 'CalID' (defined as 'String' as part of .NET Web Service) and 'SessionID' (defined as 'guid' as part of .NET Web Service). Further I need help on 1. how to create guid and pass parameter with 'guid' as type. – user698555 Apr 11 '11 at 12:02
@user698555: if `guid` is a primitive type you could just treat it as a string/integer/... as there's no real integration between .net and ksoap. If it's a complex type, you'll have to make a Java version of that type and make it implement `KvmSerializable` and `Marshal`, see some articles about that here: http://seesharpgears.blogspot.com/search/label/ksoap (please remember to accept the answer if the question was satisfied, thanks!) – bigstones Apr 11 '11 at 13:13

Spent 2 days trying to get this to work with java and .net and have finally got it working..

ArrayList<HeaderProperty> headerProperty = new ArrayList<HeaderProperty>();

headerProperty.add(new HeaderProperty("guid", "value..."));

androidHttpTransport.call(soap_action,envelope,headerProperty);

tried the above example and would add a header section but wasn't compatible with .net.

My piece of code works but requires KSoap2 version ksoap2-android-assembly-2.5.7-jar-with-dependencies.jar from here: ksoap jar file location

right click and view raw file and click save as.

Thanks for all the help in the forums as pointed me in the right direction...
