I don't know if this is the place to point this out, but it looks like the docs on the Apache website need a bit of work.
When I go to http://struts.apache.org/release/2.3.x/docs/unit-testing.html, I got a warning pop-up window saying: "Syntax Highlighter: Can't find brush for: xml" That happens on quite a few of the 2.3 pages, but none of the 2.2 pages. - Eric MacAdie
