The Apache POI team is pleased to announce the release of Apache POI
3.8 beta2. Featured are significant performance improvements and
numerous bug fixes.
The Apache POI Project's mission is to create and maintain Java APIs
for manipulating various file formats based upon the Office Open XML
standards (OOXML) and Microsoft's OLE 2 Compound Document format
(OLE2), such as Excel, PowerPoint, Visio and Word.
For more information on Apache POI, visit the project home page:

People interested should also follow the dev mailing list to track
further progress.

Pre-built versions of all POI components are also available in the

http://poi.apache.org/subversion.html should have all you need on getting
the code, and http://poi.apache.org/guidelines.html covers contributing
back

Hi Nick,
Up to my neck in code at the moment, but if you send me the pointers to what is required, i can download the source
and take a look.

NPOIFS will offer this - it's able to change the contents of a stream
where the existing POIFS code can only write new ones. However, write
support in NPOIFS isn't quite finished yet. If you're interested in
helping out, I can give you some pointers on what's needed.

Manipulating LARGE files
Posted by "Dave Irving (Delcam)" <da...@delcam.com>.
I understand that some work has been done to enhance working with large files., (>300Mb), and reduce
the memory footprint of the libraries.
Is it yet possible to load a single stream from the poifs system, and write it back without having to
use the memory based model.
i.e. there is an event based stream reader, but is there yet an event based writer.
Also, does this allow one to access the property sets via the event mechanism?
