I think the important thing here is that your JDBC version is compatible.
Metalink note 207303.1 lists compatible client and server versions. As of
today, it says that clients 10.1.0 and newer are supported, 9.2 is on
extended support and 8.1.7 used to be supported. Frankly most versions will
be functional (since they all use the same basic wire protocol) but I'd
avoid the older versions if possible.
There was a bug with some older JDBC clients that prevented failover. (Bug
2834792, Aug 2003.) I had a client a few months ago who had to use an older
version of the JDBC client because of some unresolved problems with the new
versions (I think around multithreading and VARRAYS getting returned from
stored procedures) and this put them in quite a pickle when I pointed out
that they needed to upgrade to fix their RAC failover problems. But you
shouldn't have any problems running Tomcat with RAC.
