Subject New POI (stable) release 1.0.2 (Serialize XML as Excel with Cocoon)
Date Fri, 11 Jan 2002 06:00:01 GMT
The POI project is a project for porting OLE 2 Compound Document format
based file formats (XLS/DOC/etc) to pure java.  

POI 1.0.2 provides the 

1. POIFS API for reading and writing OLE 2 Compound Document Format
2. HSSF API for reading and writing Excel 97 files
3. HSSF Serializer for serializing gnumeric-styled XML as Excel
Spreadsheets (XLS).
4. Documentation and easy to install Samples which build on the existing
samples (Thanks to Cocoon's own Ken Barozzi).

Using the HSSF Serializer it is very easy to create Excel Spreadsheets
(XLS) via Cocoon 2 from simple stylesheets.  Possible use cases involve
general presentation of columnar data to XLS based reporting.

The POI people

This is a maintenance release of the existing stable build.  While it
fixes a bug of limited interest to the majority of the POI user-base,
its an important fix nonetheless.  

Specifically this bug is improper reading and writing of single cells
containing large strings (>~8228 bytes). 

Those using 1.0.1 who do not use this behavior do not need to upgrade. 
(Though we'd appreciate it if you did).

Version 1.0.1 was released immediately before this bug was discovered
and did not get widely announced (because of this).  It is recommended
that the 1.0.0 edition not be used as it contained a more serious but
rare bug in which strings would not be written correctly on an
intermittent basis.  Specifically if the sheet contained at least two
~8228 blocks of string data and the last string broke evenly along the
second or subsequent blocks, the workbook would be rendered
incorrectly.  Although your chances were slim and none, this was a
fairly dangerous bug.
