i think that classes12.jar are jdbc drivers for java 1.2, for java 1.4
and above you must use ojdbc14.jar.
In the name of the jar file there is not the Oracle version. I use
drivers of 10g to connect to 9i without any problem.
See the oracle documentation, i believe that oracle certifies
compatibility of 10g drivers with 9i (release 2, because
previous release are not supported)
