I am pleased to say that I'm able to find most things I need working through CMP in JBoss by combining the various references I have obtained, including Dain Sundstrom's book on the subject. I have no objection to buying another copy, as mine seems perhaps to be dated a bit (I saw a note about Gangster-Hideout or some such in a post a few days ago, and my copy has no such relationship), but--and not that $10 is at all too much to ask--would like to know that I'll be getting something different. I can find no version number for the book, or indication on Flashline that's it's been updated, but would it be too much trouble to ask whether or not a recent version has appeared?
The flashline page has the following version on it:
JBossCMP 2.0 Docs Version 6.10.2002
The version number is the release date (US format). Also the new doc is in PDF.
