Q. How do I do basic authentication in JAX-WS ?

You can do the following:
HelloService service = new HelloService();
Hello proxy = (service.getHelloPort());
((BindingProvider)proxy).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "userfoo");
((BindingProvider)proxy).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "passbar");

USERNAME_PROPERTY, PASSWORD_PROPERTY are used primarily for service requests. I think when you instantiate Service, it fetches WSDL and the server is returning 401. You could try any one of the following solutions.

• 1. Use java.net.Authenticator class in your client application.
• 2. Provide a local access to the WSDL using catalog. There is a catalog sample in the jax-ws distribution.
• 3. Configure web.xml to allow GET requests without authentication
