WLS 10.3.3 - Web service - NTLM authentication

Question

Hi,
We have generated web service proxy based on a wsld file for a .Net web service secured with NTLM authentication.
Running the code that connects to the web service from a java class main method works fine, but when running the same code from a web application deployed on weblogic server (we have tried both integrated and standalone) we get the following error: com.sun.xml.ws.client.ClientTransportException: The server sent HTTP status code 401: Unauthorized.
Is there something that we should set in weblogic?
Regards,
Delia

Delia,
We had exactly the same issue and it took ages to resolve! Oracle didn't have a solution so I knuckled down and eventually worked out a solution...
When running your JAR under WLS you may have noticed that the exception looks like this:
java.io.FileNotFoundException: Response: '401: Unauthorized' for url: 'http://+your.domain.here+/default.aspx'
at weblogic.net.http.HttpURLConnection.getInputStream(HttpURLConnection.java:474)
Notice that it is not using the java.net.HttpURLConnection as you might have expected (and your Java code explicitly imports!), rather it employs weblogic.net.http.HttpURLConnection and there lies the rub.
As it turns out, it is easy to have your code force the use of the handler you desire.
Instead of:
HttpURLConnection http = (HttpURLConnection) new URL(+yourURL+).openConnection();
Use:
URL url = new URL(null, yourURL, new sun.net.www.protocol.http.Handler());
HttpURLConnection http = (HttpURLConnection) url.openConnection();
