There's a patch mentioned in the faq's that I found when trying to sort out a different problem that may sort you out.
I went with the messy c:\prog~01\... fix which isn't guaranteed to be good for everyone.
best of luck
Thanks for the referral. The FAQ entry addresses problems with JBoss once it's actually running (it's a mod to the XML config files), but this problem affects the batch file and keeps it from launching JBoss to begin with.
However, the "messy" approach you mention sounds like it will satisy my needs for now. Thanks again !
