Thanks, it now works !! What I added was the portcomponent, I specified: @PortComponent(authMethod="BASIC", transportGuarantee="NONE") At the moment I am not interested in SSL communication. Also I don't use Tomcat, but thanks for the advice, perhaps in the future. In my VB code, I removed the domain login, since user/password as in your VB example works perfectly. In the VB code, it was necessary to override GetWebRequest, otherwise the first call would result in a HTTP 505 error. Now I am able to finish my dll, include it in the InfoPath form (and add the cabinet file) and access my webservices via authentication. Thanks !
