Hello,
I needed AutoIt in a "mostly"-Java project (don't ask ..) and decided to wrap the .dll via Java Native Access. It went suprisingly well so I decided to share my results with you guys. You can fork/download the project and it's sources via Github. Feedback is always apprechiated (ideally on github, but I'll try to also check this topic from time to time).
PS: Since I'm not really an active member of this community, I encourage the mods to state any formal problems with this topic.
