Is there anyway to write some sort of plug-in for JasperReports to
get it to play more nicely? Are there nice reporting tools for
Hibernate that may have a better impedance match to EOF?
It appears to me from gleaning the JasperReports API that this work
has already been done. There are multiple subclasses of JRDataSource
that provide access to Java collections, array maps, and XML data
sources.
Give it a closer look and see if there isn't some way to integrate
reasonably well with JasperReports, Seems to me the XML data source
option might be doable with less work than you're proposing. Plus
this way you can take advantage of the JasperReport GUI design tools.

Hi everyone,
I've been reading some of the posts on this list about generating
PDFs and reports from WebObjects, and also getting really
frustrated with the "impedance match" between EO and something
like JasperReports (which seems to expect people to write sql
queries to extract data).
What I'm thinking of doing for the couple of projects I'm working
on, and for anyone else who wants to use it, is writing some kind
of reporting framework/subsystem that integrates well with
collections of data objects.
My first-cut vague design would require objects that may be
included in a report to be JavaBeans (use getXX and setXX), and
to implement a simple interface (maybe 2 methods?). The report
design would be in XML, which the reporting engine would use to
query the collection of data objects and construct an
intermediate representation (an in- memory DOM tree?) which could
then be transformed to one of a number of output formats using
XSL or FO or what have you.
There's a high probability that something like that would be
unusably slow. Reports tend to require lots of data etc.
