Midlet Installation Problems

Do you know the depressing moments when your JME application doesn't start? Or can not be installed although everything was fine on simulator or even on the different device?

The system is normally not much help at all so you spent hours guessing and trying: software development at it's worst.

Often it's simple a system check of properties in some of the files (often much too strict if you ask me). This could be a version number that contains a wrong formated build-number (Midlets need major.minor.build instead of major.minor.build.revision) or signature hashes written by your build tools into the manifest file.

Next time when you don't have a clue this document could help as a checklist (thanks to my colleague Yousuf who found this document):
