What is JAVA_HOME set to? You could be running into the findstr problem (see http://wiki.jboss.org/wiki/Wiki.jsp?page=FindstrCommandNotFound). If that is not the problem, comment out the "echo off" statement in run.bat, run it again, and post the output. Also, where did you install JDK 1.6? Hopefully not in Program Files like it defaults to. I have my JDK c:\apps\jdk1.5.0_14 (I do not run JBossAS 4.2.2 with 1.6 because it has not been qualfied with 1.6, only 1.5).
