I want users to be able to log into my website with OpenID, but I don't know开发者_StackOverflow which library to use. I know which ones are out there, but I would like to know which one would be best. I'm running JOnAS, but no web framework (no Spring, Struts, GWT, etc.). (Please don't chastise me for not using a web framework. I have my reasons.) For what it's worth, my web site is broken into multiple WARs, and I would prefer something that works well in that situation, but that's not a big deal.

Does anyone have experience with the different libraries? Any experiences or wisdom you can share?
