Looking for Struts 2 Recipe Ideas

Hi,

I am in the very early stages of a possible Struts 2 recipes type book, and was wondering if anyone who happens to visit here had any particular recipes they would like to see?

The other author has posted some ideas in his blog here.

Some of the specific recipes i had in mind, in addition to those listed on Mark's blog, were:

1) Paging
2) generating a pdf using itext
3) Custom/restful urls
4) custom components
5) Integrating with DWR
6) Using the JSF view (though i dont know JSF at the moment)
7) Using the Zero Config stuff
8) Using some of the other newer S2 plugins

Thats just a quick list of some specific ideas..but we would like to know what other Struts 2 users would like to see. So, if you have something you think would make a good recipe, leave a comment!
