The Manifest file is required for the Jar file. It defines a lot of what the JAD file can define, but sometimes you only have the Jar, so the Manifest is the only thing that the device can read. If there isn't one in the Jar file, then how can the mobile device know which is your MIDlet(s) and which aren't.
I'm using a Nokia Developer Suite.. and when i create a package, the only things that the program generates are the .jad and .jar files?
I installed the package thru bluetooth(Nokia PC Suite). I only copied the .jar file , the program runs OK in my celfone.. So, it seems i don't need the Manifest.mf anymore? or is is already inside the .jar file?
