<a href="http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.12/">Tomcat 4.1.12</a> ought to work fine. Just don't get the LE version, since that requires JDK 1.4 (unless you download a separate XML parser). <a href="http://developer.apple.com/internet/java/tomcat1.html">Apple's guide to installing Tomcat</a> should still apply.
