For visitors arriving here from somewhere other than the Stripes Book web site, a little background is in order: read this blog post, then hurry back here. We'll save you a seat.
This is a hot-button topic for me, so I'm dusting off my own blog to defend Freddy and his hungry baby (mostly because I couldn't get the BBCode to give me proper line breaks, resulting in this being a Giant Blob o' TextTM and gave up trying)
So, I purchased the Stripes Book -- both versions. It's well written, it's funny in places, is eminently useful, quite "pragmatic," and the Father of Stripes shares his wisdom in numerous side-bars. Thank you for the hard work, Freddy -- and Tim and PragProg folks.
In my case, I'm actively building a web app using Stripes, so the book is already dog-eared, written-in and care-worn. It's my first JSP/Servlet/MVC framework app. Luckily, I had the luxury of choosing the app stack. I looked at a bunch of Struts books (easy to find at B-and-N or Borders) and at as many on-line references as I could find for Stripes, Spring MVC, Tapestry (the folks at Apache stay busy, don't they?), JSF, etc.
