Asunto: RE: Modify word document
You are welcome.
If you do not have access to 3.2 FINAL of the API, it is possible to
download older releases from here -
http://archive.apache.org/dist/poi/release/bin/. Must admit that I do not
know what changes were made to HWPF between 3.2 and 3.5 so cannot say why
the formatting information is being lost and can only hope that you will ne
able to revert to using 3.2 FINAL for this project.
All that you will need to do is to ensure that both the scratchpad and POI
archives are in your classpath and you should be able to successfully
compile and run the code. Any problems, just let me know.
Yours
Mark B
