Weblogic 8.1 Webservice Client Proxy Authentication not working

Question

We have a desktop console based Weblogic webservices client application that uses client stubs to establish the connection and communicate with the server where the WSDL was hosted.
We are facing a problem in authenticating the Proxy user with valid credentials.
We are using the following code to set the system properties and Authenticator class to authenticate the proxy user.
//Code Segment #1
Code:
System.setProperty("http.proxyHost", proxyHost);System.setProperty("https.proxyHost", proxyHost);
System.setProperty("weblogic.webservice.transport.http.proxy.host",proxyHost);
System.setProperty("weblogic.webservice.transport.https.proxy.host",proxyHost);
System.setProperty("http.proxyPort", proxyPort);
System.setProperty("https.proxyPort", proxyPort);
System.setProperty("weblogic.webservice.transport.http.proxy.port",proxyPort);
System.setProperty("weblogic.webservice.transport.https.proxy.port",proxyPort);
//System.setProperty("http.proxyType", "basic");
//System.setProperty("https.proxyType", "basic");
//System.setProperty("http.proxy.auth.type" ,"ntlm"); //This is not showing any impact
System.setProperty("http.proxyUser", "bsil\\ashok.kumar");
System.setProperty("https.proxyUser", "bsil\\ashok.kumar");
System.setProperty("http.proxyPassword", " xyzddd");
System.setProperty("https.proxyPassword", "xyzddd");
Authenticator.setDefault(new MyAuthenticator());
//Inner class
public static class MyAuthenticator extends Authenticator {
protected PasswordAuthentication getPasswordAuthentication() {
String username = System.getProperty("http.proxyUser");
     String password = System.getProperty("http.proxyPassword");
     return new PasswordAuthentication(username, password.toCharArray());
We are using following code initialize the stubs (Which internally opens a connection to the given endpoint base URL)
//Code Segment #2
Code:
SessionService_Impl sessionService = new SessionService_Impl(getEndPointURL(SessionServicePort.class));
port = sessionService.getSessionServicePort();
return port;
Using above code it always throws the following exception:
Code:
weblogic.webservice.tools.wsdlp.WSDLParseException: Failed to retrieve WSDL from https://apiclienttest.intralinks.com:443/webservices51/SessionService?WSDL. Please check the URL and make sure that it is a valid XML file [java.io.IOException: Proxy authenticator  failed: java.lang.ClassNotFoundException: ]
if i replace the above code (Code Segment #2) to as bellow with Code Segment #3 then its working as expected. But we have been told that the Code Segment #2 is required as shwon above for the Weblogic ClientTimeout seconds feature so we cant replace the Code Segment #2 with Code Segment #3 since we don?t want to miss the ClientTimeout seconds feature for the application.
//Code Segment #3
Code:
SessionService_Impl sessionService = new SessionService_Impl();
          SessionServicePort sessionServicePort = sessionService.getSessionServicePort();
          ((SessionServicePort_Stub) sessionServicePort)._setProperty("javax.xml.rpc.service.endpoint.address", endPointBaseURL+"SessionService");
return sessionServicePort ;
why the Proxy authentication is failing with the Code Segment #2 and why it is passing in case of Code Segment #3
The endpoint base URL we are hitting is hosted on Weblogic server 9.0 (which is hosted at client side in US so it is behind our firewall).
Is some thing more do we need to do in Authenticator class???
Please help me if any one has worked on proxy server authenticator in java.
