[Persistence, JBoss/CMP, Hibernate, Database] - "Could not obtain connection metadata' when generating Hiber
by gbadavidson
I am attempting to use Hibernate with JSF/Facelets on the JBoss AS. When the application attempts to build the Hibernate Session Factory an error is thrown "Could not obtain connection metadata", yet the driver is listed a few lines eariler in the log. Here is the relevent lines from the log and then the Hibernate configuration file. :

Deployment Errors on startup of JBOSS
by Mike Hancock
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:
