Issues getting the Tomcat bundled with Magnolia to start
I kept getting an error message saying that the BASEDIR environment variable was incorrectly set. This went away once I'd made lots of stuff executable in the Tomcat bin directory.
This was a weird file permissions thang!

Getting JSTL EL working on Tomcat 5.0.x
I copied my content into the correct folder but some of my EL expressions weren't working.
This is because I needed namespace declarations in the <web-app/> tag in the web.xml file:
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">
