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.
