Cannot create JDBC driver of class '' for connect URL 'null' java.lang.NullPointerException

The server loads fine (with no errors or warnings) however, certain images don't display correctly. I had to fiddle around with class paths to get the server running so I'm wondering if its something to do with that? Anyway heres my log, would really appriciate some help. I only recieve errors when I switch between a few pages...
