Java APIs

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);
	}		
    }
}
