Ok,
I've updated the getName():
public String getName() {
return "ical";
}
which now matches the definition in the hivemodule.xml:
<contribution configuration-id="tapestry.services.ApplicationServices">
<service name="ical" object="service:ICalService" />
</contribution>
<service-point id="ICalService"
interface="org.apache.tapestry.engine.IEngineService">
<invoke-factory model="singleton">
<construct class="ICalService">
<set-object property="eventDAO"
value="spring:eventDAO"/>
</construct>
</invoke-factory>
</service-point>
When I hit UpcomingEvents.html I still get the stack trace and
nothing in the console (catalina.out) about the service being discarded.
Here is the complete stack trace:
No engine service named '<SingletonProxy for
eventscalendar.ICalService(org.apache.tapestry.engine.IEngineService)
>' is available.

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() {

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.
