Digest password validation using JAX-WS in Spring for webservice client

I have a Spring application that uses JAX-WS to use another web service. Everything is working fine, but now this web service has switched to the need for digest passwords. How can I accomplish this using JAX-WS?

In the Sprig documentation, I see that this should be possible, but I cannot find code examples with JAX-WS: http://static.springsource.org/spring-ws/site/reference/html/security.html#d4e2684

Has anyone done this before? Any code samples would be appreciated.
