I have it working (Score 2)

I hope you want to find out how to setup a webserver to serve WML (Since the WAP part happens after a WAP gateway, pulls the WML content from a WML webserver and sends it over the Internet). I have it working and have tested this against real and emulator phones. I run Apache with JServ. In simplest of requirements, all it requires is setting up the mimetypes (atleast for vnd.wap.wml and possibly 4/5 more). Then in your servlet you will setContentType("whatever you want to server"). Note that it is also possible to setup the webserver to intelligently serve pages depending on the end-agent (browser?!) and serve either wml or html etc... in Apache.
