Eclipse Web Services Test Client and Exception: (401) Unauthorized error

I am trying to test a user/pw protected web service using the "web services test client" in Eclipse IDE. I am able to generate the client but when I test any methods I get the exception: (401)Unauthorized er开发者_如何学编程ror. How do i get about putting the username/pw authentication so that my client is able to call the functions successfully?

Thank You
