This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I'm interested in the various login/authentication code that reused other folks' implementations. The Open ID idea seems interesting, but I'm finding the documentation a bit opaque. Even the Tutorials seem to be missing critical parts. I feel like I'm trying to learn Unix from the man pages age, where the information is correct in each man page, but they are so dependant on stuff in other man pages, that you have to read hundreds of them to figure out how to start.
In a standard servlet/jsp container world (tomcat, glassfish, etc.) how do I start? I assume that the OpenId4 java login functions replace my Login bean, that is mapped to a filter in the usual web app XML file. But I'm just not seeing if this is right, wrong, or off planet.
