I posted the same question last week and the response was, in a nutshell,
not for version 3.1 since it relies on the version of the xml parser that
comes with it. For 3.2, you can change the classpath in the startup
script and place your xml parser in front of theirs, but that is not acceptable
to me. For v4.x, there will be a way, but I just downloaded the latest
milestone of Tomcat v4 (milestone 4), and I am having a problem running
my web app as-is. Since it is a beta, documentation is scarce, so
I guess I we just need to hack around until an answer is found :-(
Good luck,
Dan
