How can I get the UserName in JAX-RPC?

Question

The client is just as following:
import javax.xml.rpc.Call;
import javax.xml.rpc.Service;
import javax.xml.rpc.JAXRPCException;
import javax.xml.rpc.namespace.QName;
import javax.xml.rpc.ServiceFactory;
import javax.xml.rpc.ParameterMode;
public class ACTRPCClient {
private static String qnameService = "Hello";
private static String qnamePort = "Greeting";
private static String BODY_NAMESPACE_VALUE ="http://hello.org/wsdl";
private static String ENCODING_STYLE_PROPERTY ="javax.xml.rpc.encodingstyle.namespace.uri";
private static String NS_XSD ="http://www.w3.org/2001/XMLSchema";
private static String URI_ENCODING ="http://schemas.xmlsoap.org/soap/encoding/";
public ACTRPCClient() {
public static void main(String[] args) {
try {
String endpoint= "http://127.0.0.1:8080/SOAPListener/Hello";
ServiceFactory factory =ServiceFactory.newInstance();
Service service =factory.createService(new QName(qnameService));
QName port = new QName(qnamePort);
Call call = service.createCall();
call.setPortTypeName(port);
call.setTargetEndpointAddress(endpoint);
call.setProperty(Call.SOAPACTION_USE_PROPERTY, new Boolean(true));
call.setProperty(Call.SOAPACTION_URI_PROPERTY, "");
call.setProperty(ENCODING_STYLE_PROPERTY,URI_ENCODING);
//here I set the username and password
call.setProperty("javax.xml.rpc.security.auth.username","tomcat");
call.setProperty("javax.xml.rpc.security.auth.password","tomcat");
QName QNAME_TYPE_STRING = new QName(NS_XSD, "string");
call.setReturnType(QNAME_TYPE_STRING);
call.setOperationName(new QName (BODY_NAMESPACE_VALUE, "getHello"));
call.addParameter("Greeting", QNAME_TYPE_STRING, ParameterMode.PARAM_MODE_IN);
String[] params = { new String("Hello!") };
String result = (String)call.invoke(params);
System.out.println(result);
} catch (Exception ex) {
ex.printStackTrace();
On the server side,I wrote a my own servlet to receive the soap instead of the jax-rpc.But I can't get the username from the request.
for example,
String username;
username=request.getRemoteUser();
I noticed that in the api doc,it says when the user has not been authenticated the method getRemoteUser will return null.So I use the username "tomcat" ,password "tomcat "in the tomcat-
users.xml.But I still can't get the username,why?
Thanks for your help.

From the Axis I find the problem,the username and password is stored in the headers of the http.
And now the jax-rpc only surpport basic authentication,we can get them by calling request.header("Authentication").Howerver,the infomation is encoded by Base64.We copy a module from the Axis to decode the infomation.That's it,but still thank your attention.
