Thanks.
I used
Configuration.bootstrapSharedConfiguration(iiv_test.SiteDailySum.class);
and was able to build without an error. But the running the program still
gives me:
WARN EntityResolver: *** Class 'SiteDailySum' not found in runtime.
Ignoring.
java.lang.IllegalArgumentException: Can't find ObjEntity for DataObject
class: iiv_test.SiteDailySum, class is likely not mapped. at
org.objectstyle.cayenne.access.DataContext.registerNewObject(DataContext.jav
a:889) at iiv_test.CreateReport.cayenneReport1(CreateReport.java:29) at
iiv_test.CreateReport.main(CreateReport.java:20) Exception in thread "main"
Thanks,
Roy

Roy,
My bad, it should be "iiv_test.SiteDailySum.class", as we need an
object of type java.lang.Class there:
Configuration.bootstrapSharedConfiguration(iiv_test.SiteDailySum.class);
