call a method on Navision webservice using NTML authentication using Java

Question

I've created a SOAP web-service client on Netbeans. The web-service is exposed on Navision with NTML authentication. During class generation, a login pop-up picks the required credentials and uses them for authentication. The issue is once the classes are generated and I try to invoke any method;

    ServicePort webservice_port = new WService().getServicePort();
    webservice_port.retrieveData();

I get an exception.

java.io.IOException: Server returned HTTP response code: 401 for URL: ...

Exception in thread "main" com.sun.xml.ws.wsdl.parser.InaccessibleWSDLException: 2 counts of InaccessibleWSDLException.

Is this an issue with NTLM authentication or is there another way to pass the credentials?

Answer 1

Found a working solution. Injecting an authentication mechanism to the client using the web service port.

        Port webservice_port = new Wservice().getServicePort();
        Client client = ClientProxy.getClient(webservice_port);
        HTTPConduit conduit = (HTTPConduit) client.getConduit();
        AuthorizationPolicy authorization = conduit.getAuthorization();
        authorization.setUserName(username);
        authorization.setPassword(password);
        conduit.getClient().setAllowChunking(false);
        conduit.getClient().setAutoRedirect(true);
        webservice_port.callWebMethod();
