Generate JADs from JARs the easy way
Over the course of my browsings I’ve often found a useful MIDlet on the internet that ships a JAR file, but not a JAD.
For some reason a few CDMA carriers have a pedantic policy whereas locked phones must use over-the-air-provisioning (OTAP) using JADs, being unable to extract the info they need from the JAR file themselves. After a good bit of searching, I found an article on the Nokia wiki which explained how to properly create a JAD from the JAR’s manifest file.
However, if you’re lazy, you might just want to go to the automated JAD generator.
EDIT: http://rumkin.com/tools/sprint/index.php seems to do a better job than any of the above tools, with the added bonus of emailing a link to the JAD to your phone.
