I'm also facing the same problem. The installation instructions for jBPM4 is clear as a crystal but it's predecessors lags 'em. The installer type of versions like jBPM-3.2.6-installer is better with step-by-step GUI based installation. I will try jBPM-3.2.6-SP1 and let you know if it works with jBoss-4.0.5.
