Did you ever get an answer to how to get the client to use <wsse:Security>? I have been following this thread closely because it reflects my own experience and even my own suspicion that the client needed something similar to the HandlerChain on the server side, before I read your post. I incorporated standard-jaxws-client-config.xml in my own build but with both signature & encryption required, am also still getting javax.xml.rpc.soap.SOAPFaultException: This service requires <wsse:Security>, which is missing.
