Authenticator in Axis1.4

Hello everybody,

I am facing some Authentication problem using the Axis1.4, I have this
code for Axis2

// Authentication
			Options opt = stub._getServiceClient().getOptions();
			Authenticator authenticator = new Authenticator();

			List<String> auth = new ArrayList<String>();
			auth.add(Authenticator.DIGEST);
			authenticator.setAuthSchemes(auth);
			authenticator.setUsername("username");
			authenticator.setPassword("password");
			authenticator.setDomain("DOMAIN");		
			authenticator.setHost("localhost");
			opt.setProperty(HTTPConstants.AUTHENTICATE, authenticator);
			opt.setSoapVersionURI(org.apache.axiom.soap.SOAP11Constants.SOAP_ENVELOPE_NAMESPACE_URI);
// SOAP 1.1 required

Using some imports:
import org.apache.axiom.soap.SOAPFaultDetail;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.transport.http.HTTPConstants;
import org.apache.axis2.transport.http.HttpTransportProperties.Authenticator;

That is not available in the Axis1.4.
Do you know how can I handle this type of authentication in Axis1.4,
considering that I do not have the
transport.http.HttpTransportProperties.Authenticator, available in
Axis1.4?

Thanks in Advance,
Francisco
