This message is a bit misleading and is definitely should be made more informative,
but generally it means that the server was not able to find a database driver jar or one of it's
component, like binary DLLs or SOs in case of a type 2 JDBC driver.Make sure that a jar containing database driver is included into the server startup CLASSPATH
set in server startup script, the driver name and URL are correct, and that driver's binary libraries,
if any, are available (for Windows they should be in the server PATH, and for unix in LD_PATH).
