Good afternoon,

I tried out grouper installation first by installing in on my desktop (Mac OS/X) and using the hsqldb.  Although it was 100% smooth, I was able to reason out what was needed to completed the installation and had grouper up and running within a day.

The RHEL installation is not going well.  In production, we will be using Oracle rather than the bundled database.  

By reading the documentation and reviewing the tutorial, it is implied that all drivers needed for an installation are included in the installation package.  However, once I have entered the hibernate.connection.url, hibernate.connection.username, and hibernate.connection.password, the program throws the following exception trace (despite adding the ojdbc14.jar driver to a library and including it in the classpath.  The lines indicating issues in finding ojdbc14.jar are in red):

Checking database with query: select 1 from dual

We need to get a replacement for our current role management system prototyped and available for users ASAP, so anything you can suggest would be most appreciated.
