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.
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?
