For XSRF, there are no good solutions other than what appears at this link, and in Chapter 10 I provided a link to it, but also provided some other methods based on hashes and digital signatures. As to Spring, I didn't use it, but will probably reconsider that since GWT 2.1 appears to be heading in Spring's way.
Hope this helps!
Great fan of Open Source, Linux, and web development with GWT; all of these come together for my ESSENTIAL GWT book!

Thank you for the reply! I will definitely check out the other methods in your book. I'm also interested in your MVP approach since you hit the nail on the head in another thread outlining the issues you’ve encountered with the existing libraries. e.g. nested widgets etc...
