Simple example required

[Andrew Fielden <af...@tibco.com>]

I've looked at the WSS4J examples, but still don't fully understand how
it fits together with calling a web service using Axis.
I'd like to be able to add SAML tokens to a SOAP message, but I have a
couple of basic questions:

1. The examples make use of a callback class to manipulate the SOAP
message. How is this callback class registered, in the context of the
example below.

2. The examples get a reference to the SOAP envelope object, but how do
I obtain this, in the context of the example below.

Thanks for any advice.


1   import org.apache.axis.client.Call;
2   import org.apache.axis.client.Service;
3   import javax.xml.namespace.QName;
4   
5   public class TestClient {
6     public static void main(String [] args) {
7       try {
8         String endpoint =
9             "http://ws.apache.org:5049/axis/services/echo";
10  
11        Service  service = new Service();
12        Call     call    = (Call) service.createCall();
13  
14        call.setTargetEndpointAddress( new java.net.URL(endpoint) );
15        call.setOperationName(new QName("http://soapinterop.org/",
echoString"));
16  
17        String ret = (String) call.invoke( new Object[] { "Hello!" }
);
18  
19        System.out.println("Sent 'Hello!', got '" + ret + "'");
20      } catch (Exception e) {
21        System.err.println(e.toString());
22      }
23    }
24  }
