Subject: [OS-webwork] Jasper Reports

Just realised that not everyone will be on the new list yet.

===8<==============Original message text===============
I have just committed some updates to the Jasper Reports support.
Since this is my very first commit I would appreciate any feedback.

In this update:
- Subreport support to support nested iterators along with updated
examples.

Note that the way that I have implemented subreports is to have the
ValueStackDataSource return another ValueStackDataSource if the field
you specify via expression language turns out to be iterable (List,
array, Enumeration etc). If you actually want the value of one of
these objects in your report you will have to create another property
that returns the toString of the property.

Barring changes to Jasper Reports itself (like adding a new method on
JRDataSource) this was the cleanest way to do this even though it was
a kludge.

Still to do:
- Add support for compiling the reports in the build
- Add support for passing the webwork parameters to Jasper

Try this out and let me know if you like it.
