Java libraries that work with Microsoft Office documents but do not depend on automation

Question

By "not depend on automation", I mean that it should not require a Microsoft Office installation to work; let alone interact with a live instance of a Microsoft Office component. One such library is Aspose.Total for Java. Are there any more out there?

Another solution I'm considering is to use OpenOffice.org. However, I'm not sure if I'm going to run into the same problems as with Microsoft Office as detailed here.

Answer 1

For Office Documents: http://poi.apache.org/

I have not tried this myself, but Apache usually deliver good libraries

For just Excel: JExcel API for Java

I use this for one application, and it works quite well. May use a fair bit of RAM for larger documents.
