I think so. Tomcat 4.1.x relies on DBCP 1.0 whose docs aren't readily
available anymore. If you can find the source for DBCP 1.0, you could
take a look in the source code and get that answer. Or you could just
try it on your test system and see if it works. :-)
The manner the validation query is added to tomat's config is different
though. You add it in the ResourceParams element the same way other
properties are defined in your version.
