To see the topics covered, go to the book's web site (the link is in my signature). The other JBoss books either focus on internals (the ones from the JBoss team) or on application development. Ours focuses on administration and configuration.
JBoss in Action is different from other JBoss books on the market because of several reasons:
* JBoss in Action covers JBoss Application Server (AS) 5.x. All of the other books that are available cover JBoss AS 3.x or JBoss AS 4.x. * JBoss in Action is not stuffed with complicated explanations and disorganized content that lacks sufficient background. If you�ve spent some digging through the JBoss wiki, the JBoss documentation, or JBoss 4.0 - The Official Guide, you�ll appreciate this. * JBoss in Action focuses on teaching you about the application server, not Java EE programming. The book JBoss at Work is great for learning how to program Java EE applications for JBoss, but it doesn�t give you enough detail on how to configure and operate the more advanced features of the application server. * JBoss in Action covers a wide range of topics. The book JBoss: A Developer�s Notebook is very well written and is very practical, but it only gives you enough information to get your feet wet.
