Use of a secured proxy with SOAP

Question

Hi all,
I have a java client that tries to connect to our SOAP server through a proxy.
I have no problem with normal proxies but I do however when it's a secured proxy (with authentication).
I have tried several solutions:
1- The use of the system properties like for the normal proxies (+http.proxyHost+, http.proxyPort, http.proxyUser and http.proxyPassword), but it did not work (Error 407: Proxy Authentication Required).
2- A simple class derived from the java.net.Authenticator (code below) but still the same error.
3- Change the properties of the call directly but it might be used by axis only so again the same error.
The main problem comes from the fact that I am using SOAP (apache axis) to start the connection (see code below).
I would appreciate any inputs/remarks because I am really lost at this point.
I can try whatever you may advice me to do since the system is all mine.
Many thanks in advance and best regards.
Rob
The HttpAuthenticateProxy class
import java.net.Authenticator;
import java.net.PasswordAuthentication;
public class HttpAuthenticateProxy extends Authenticator {
    private String username;
     private String userpass;
    public HttpAuthenticateProxy(String user, String pass) {
        super();
     username = user;
     userpass = pass;
    protected PasswordAuthentication getPasswordAuthentication() {
     return new PasswordAuthentication(username,userpass.toCharArray());
The SOAP client class
/* SOAP classes */
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
public class SOAPClient {
    public static Service service = null;
    private static Call buildCall(String method) throws ServiceException {
     if (service == null) {
         if (GlobalProperties.getHttpProxyHost() != null && GlobalProperties.getHttpProxyHost().length() != 0 && !GlobalProperties.getHttpProxyHost().equalsIgnoreCase("null")) {
             // Secured proxy.
              if (GlobalProperties.getHttpProxyUser() != null && GlobalProperties.getHttpProxyUser().length() != 0 && !GlobalProperties.getHttpProxyUser().equalsIgnoreCase("null")) {
              System.setProperty("http.proxyHost", GlobalProperties.getHttpProxyHost());
              System.setProperty("http.proxyPort", GlobalProperties.getHttpProxyPort());
                    /* my first attempt */
              System.setProperty("http.proxyUser", GlobalProperties.getHttpProxyUser());
              System.setProperty("http.proxyPassword", GlobalProperties.getHttpProxyPass());
              /* my second attempt */
                    Authenticator.setDefault(new HttpAuthenticateProxy(GlobalProperties.getHttpProxyUser(),GlobalProperties.getHttpProxyPass()));
              } else { // Non secured proxy.
              System.setProperty("http.proxyHost", GlobalProperties.getHttpProxyHost());
              System.setProperty("http.proxyPort", GlobalProperties.getHttpProxyPort());
         service =  new Service();
         Call call = (Call) service.createCall();
         call.setOperationName(method);
         call.setTimeout(new Integer(1800000));
         return call;
    private static Object invoke(Call call, Object[] objects) throws Exception,RemoteException,MalformedURLException {
     for (String name : GlobalProperties.getSOAPServers()) {
         call.setTargetEndpointAddress(new URL(name));
         if (GlobalProperties.getHttpProxyUser() != null && GlobalProperties.getHttpProxyUser().length() != 0 && !GlobalProperties.getHttpProxyUser().equalsIgnoreCase("null")) {
                /* my third attempt */
          call.setProperty("javax.xml.rpc.security.auth.password",GlobalProperties.getHttpProxyPass());
          call.setPassword(GlobalProperties.getHttpProxyPass());
          call.setProperty("javax.xml.rpc.security.auth.username",GlobalProperties.getHttpProxyUser());
          call.setUsername(GlobalProperties.getHttpProxyUser());               
         for (int j = 0; j < objects.length; j++) {
          if (objects[j] == null)
              objects[j] = "";
         Object ret = call.invoke(objects);
         return ret;
         return null;
    /* example of run */
    public static String stressServerAnnot(String server, String nbRuns) throws Exception {
     try {
         Call call = buildCall("stressServerAnnot");
         call.addParameter("server", XMLType.XSD_STRING, ParameterMode.IN);
         call.addParameter("nbRuns", XMLType.XSD_STRING, ParameterMode.IN);
         call.setReturnType(XMLType.XSD_STRING);
         String ret = (String) invoke(call, new Object[] {server, nbRuns});
         return ret;
     } catch (Exception e) {
         System.out.println("[SOAPClient] Error in stressServerAnnot : " + e);
         throw new Exception("[SOAPClient] Error in stressServerAnnot : " + e);

Answer 1

Yes, it's not present in the code I have posted but I have tried this as well.
It didn't work, as expected, because soap/axis is on top of http and not https and because my proxy uses http as well (or at least that's what I have learned so far).
In fact, I have tried all combinations between http.\*, https.\*, and Authenticator without success.
I think the problem is more soap/axis related. The solution for axis2 seems somewhat 'trivial' (and well explained over the web) while it's not for axis1.
