Bottom line, software is free, documentation is cheap, everyone should be happy. As I understand it there will be a quickstart doc for free and then additional docs you buy. This also ensures that docs are up to date and well-written, unlike so many other Open Source projects.
$10 for a 400 page book for a free world class application server is still so cheap it is ridiculous. If the time you would save studying the source code is not worth $10, feel free to dive in and read the well documented source rather than buying the docs.

Subject: RE: [JBoss-user] where is CMP2.0 documentation?
Why is the JBoss Group charging for documentation? An opensource project should have freely available documentation. How can a project survive if nobody knows how to set it up?
