I tried to get it to work using the CXF User Guide, but I've had no luck.
I'm trying to call the web service using java code.
This is covered by the JAX-WS Specification. Basically, set the username/password as properties on the request context:
((BindingProvider)proxy).getRequestContext().put(
BindingProvider.USERNAME_PROPERTY, "joe");
((BindingProvider)proxy).getRequestContext().put(
BindingProvider.PASSWORD_PROPERTY, "pswd");
The runtime puts them into the HTTP header.
