Actually, the link refer to both Linux and Windows. The steps are pretty much the same - download JBoss native for your platform and extract it into the bin directory such that you end up with bin\native. But you are correct in assuming that you do not absolutely need APR - JBossAS runs fine without it. The warning you get is just that, a warning that APR is not running, you can ignore it.
