POI

An Apache/Jakarta open source project to allow Java to export/import various file formats including Excel (*.xls) and MS Word (*.doc) If all you need to do is read/write CSV (comma separated value) files, you can use the much simpler CSVReader/CVSWriter classes instead.

It has a number of subprojects including POIFS for OLE 2 Compound Documents, HSSF for Microsoft Excel 97(-XP) spreadsheet documents and HWPF for Microsoft Word 97(-XP) word processing documents.

You format Word documents by defining nested styles with HWPF then applying styles to hunks of text.

POI is not what I would call developer friendly. You can get the source with CVS and build it yourself. There are some unlabelled binaries you can find by diligently poking around directories on one of the download mirrors.
