I want to know more about JBoss and its architecture and therefore am going to buy the book. My question is:
Since there is a new version of JBoss 3.xx for a long time, is this book still up to date for the new version? When not, when can I expect a new release of the book?
Thanks in advance.
you can already order a subscription PDF for the new 3.x book, see the documentation link
I recommend getting the 3.x book for 3.x version of JBoss
