Well, I think just by looking at that context.xml, I can see what I’m missing then:

<Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />

That was commented out in mine and I’ve never seen anything on that in any articles on comet  on Tomcat, but by that name and the comment above it, it has to be it.
