Using Jespa with wsimport generated client to call a .net webservice protected by Windows Authentication

I am trying to figure out how I can hook up Jespa into the client generated by wsimport, so that I can hook up to a .Net service that is using windows authentication (the java client is 开发者_开发问答running on Linux, so the built in ntlm authentication doesn't work). I would be grateful for any working examples.

Also, I can't change any global settings because this is just a small module of a large system.
