I've been trying for some time to install a working JBOSS (5.0.0.GA) without success. I've read the "Installation And Getting Started Guide" and tried to follow those instructions. I downloaded the zip file and extracted it per the guide above. I checked and added/revised environment variables, again per the guide above. I've searched the JBOSS forums for posts with similar issues - all to no avail. I would really appreciate some help with this - sample of stack trace below from boot.log:
