JBoss 3.2.x will run on any system capable of supporting a compliant Java 2 JVM at version 1.3.1 or better. Download the Sun JDK - probably get JDK 1.4.2 and install it in a directory path without a space in it. Do the same with JBoss. You'll need to have at least 128M of memory probably.
You can glean through http://www.amitysolutions.com.au/downloads/response_tester.pdf and just apply the JBoss specific portions.
Hope that helps.
