What is going to make it expensive? Once you have paid for it you download it in pdf format.
The standalone jboss-cmp book is out of date. The most upto date content is in the admin/devl guide. Propose how your research will provide $10 of improvement to JBoss and there could be a deal.
it would get a little expensive just for the US$10,00 (actually, its not expensive, the book probably worths a lot more).
My research probably won't get improvings, it's a educational research where i'm studying "why CMPs is that much better than BMPs, in performance, etc...".
Anyway, the major problem is not the US$10,00 (as i said, it's a lot resonable), but the fact that i don't have a international credit card (i'd have to borrow one, and if i say it's gonna be used over internet, the person i'm borrowing probabley won't let me, even i saying its verysign, etc...)
So, is there's a possibility for me to make a money transaction for jboss account, i would do it right now (it just got be a international bank, that we have in brazil, like Citibank, for instance).
