.jar file components
 

I have 3 games in my possession that were originally ported to Nokia devices.

I am not convinced that these games will work on my 8100 at all, as all the Nokia games (.jad files) I've tried to load OTA so far have bombed.

However, in this case, I have managed to get ahold of the individual components of the respective .jar files, instead of the .jar files themselves.

Is it possible to just change the way the components are packaged in order to get them to work correctly on a Blackberry device? Or would they need to be rewritten entirely in order to work?

I'm not much of a Java person, so any help would be much appreciated.
