Also, check the console, there should be a log error.
My current theory: service "ical" was discarded because the names didn't
match AND the code that outputs the "missing engine service" error message
is broken.

First problem I see:
hivemodule.xml:
<service name="ical" object="service:ICalService" />
public String getName() {
return "ICalService";
}
These need to be the same string. Tapestry is checking that the engine
service knows its own name, in case it generates any links.
I don't think that's your root problem.
I need to see the code from UpcomingEvents.java and a readable and
complete stack trace.
