We are currently using JasperReports with our WebObjects
apps. We wrote a custom JRDataSource that uses key-value coding into NSArrays
of EOs, and we just embed the keypath in the Jasper Report template. Our
reporting needs were very modest, mostly several pages of lists of EOs
that match a certain criteria with very little aggregation/summarizing
except a total count at the end. Plus our reports are batched nightly,
so performance is not really an issue. It worked pretty well for our needs.
We can probably provide the code if it would be helpful.
