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.
With Jasper quickly gaining popularity in the Java world, I think it
would be valuable to the community to have this WO integration
available. It sounds like you have done precisely what I had in
mind. If you do decide to release this and don't want to host it on
your side, http://www.wocode.com is probably a good home away from
home for it.
