I've used similar pieces of XP's philosophy as well - especially the
daily integration stuff. (One example is Sun's JWSDP, where I was the
implementation architect - one of the things we did was build the entire
thing from source every night, which helped flush out a lot of potential
incompatibilities; sort of like what Gump does for open source projects
<http://jakarta.apache.org/gump/>).
Personally, I've never been comfortable with pair programming, but that's
probably more a personal quirk than any statement about the value of the
concept.
One XP principle that is starting to become pervasive in Jakarta projects
is unit tests, including the notion that building tests is part of
building the code, you're not done until you've got unit tests to prove
that it works, and the idea of adding unit tests every time you fix a bug
to catch regressions. Struts itself is woefully behind the curve on this
(something I want to address after 1.1), but you'll see pretty
comprehensive JUnit based unit test suites in the source code of all the
Commons packages -- "ant test" is the usual way to invoke them.
I've gone from a "unit tests are nice" attitude to a "unit tests are
vital" attitude based on my own experience with them.
