Sometimes it happens that after downloading a Jar file for an App, there appears to be several catch with it, like activation code required. Is there any tool that I can use to simulate the Jar file on desktop prior to downloading/transferring to mobile?


What you are looking for is a J2ME emulator, there are many of them and it appears that many have some limitations such as limited 3D support, slowness and other bugs.

There is Micro Emulator which according to this site can run Opera Mini and is an indication that it is reasonably complete.

I also found Java Emulator which looks to be more game orientated.

MPowerPlayer also appears to have another Java MIDP emulator as reviewed here

There are just too many emulators to count, and you're going to have to review them to see which suits your needs best.

  • Thanks for the heads-up :). I now have resources to look into and evaluate. – Shamim Hafiz Sep 7 '11 at 5:29
  • On first hand experience, Java Emulator looks to be better. I tried with one app from Mobilerated, Micro Emulator crashed but Java Emulator was successful. – Shamim Hafiz Sep 7 '11 at 11:10
