I added the folder that contains the jar mentioned to the "path" environment variable on my machine - but I get the same issue. I assume that that is what was meant by adding that jar to the classpath. If this is not correct - is there something else I should do to add this to the classpath? If there any any other ideas I would greatly appreciate it. It seems quite a long drawn out complicatd process to tell the application to simply use a different database...... Am I missing any pre-requisites that the readme does not mention (it claims to be the step by step process to get it working on any supported db - but it don't seem to want to work for me). Many thanks. Steve. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4002390#...
