Truth be told there is probably a better way to generate your spreadsheet
|
|
|
|
|
generation (yet you'll still be using HSSF indirectly). At the time of
|
|
|
|
|
this writing we're in the process of moving the HSSF Serializer over to
|
|
|
|
|
the <a href="http://xml.apache.org/cocoon">Apache Cocoon
|
|
|
|
|
Project</a>. With Cocoon you can serialize any XML datasource (of
|
|
|
|
|
which might be a ESQL page outputting in SQL for instance) by simply
|
|
|
|
|
applying the stylesheet and designating the serializer.
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p align="justify">
|
|
|
|
|
If you're merely reading spreadsheet data, then use the eventmodel api
|
|
|
|
|
in the org.apache.poi.hssf.eventmodel package.
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p align="justify">
|
|
|
|
|
If you're modifying spreadsheet data then use the usermodel api. You
|
|
|
|
|
can also generate spreadsheets this way, but using Cocoon (which will do
|
|
|
|
|
it this way indirectly) is the best way...we promise.
