Generating excel documents programmatically

Question

Has anyone used a Java based library for generating excel documents? Preferably support for 2003?

Answer 1

JExcelApi

I've used it personally for a report that is currently in production. It's a fairly decent library with sufficient docs, and it's open source.

It works very well, but has a few gotchas you should be aware of. None of them are deal breakers, just dictate how a few things should be done. Just be sure to read the FAQ. It will explain them and tell you how to avoid them.
