Recently I discovered that OpenOffice can’t really generate RTF files, so I wrote my own converter. It’s rather basic, just handles italic, double space, paragaraphs, and centering. However, for what I need it for it works a lot better than the built-in OpenOffice export ability.
The program is written in Java and you can get the jar file here: ODT2RTF.jar
It’s completely self contained, and includes the source files. Go and have fun with it!
If there is interest, I will expand its capabilities.
