I’m trying to learn Apache POI for Java quickly (for manipulating Excel). I’ve been googling for tutorials, but so far all I’ve found is short, 2-paragraph explanations followed by a code sample. I wanted to find something a bit more comprehensive, that is concise but walks through it in a structured, complete, and understandable way. Anyone know of any good tutorials? Does Apache POI have any decent documentation…? I couldn’t seem to find any on their site.

    I found the documentation to be mostly lacking myself. I found the mailing group was my best resource for getting answers to my hard questions: http://mail-archives.apache.org/mod_mbox/poi-user/. For learning the basics I just followed the examples on the online documentation and used the trial and error approach with a simple console app.

    Online documentation links:
