How To Run Java Mobile Apps (J2ME) On PC
J2ME Applications are made for mobile phones, which is a different platform than Windows. It is not possible to run these apps directly in Windows, however there is a cool thing named KEmulator. It's a J2ME emulator that emulates the Java Mobile environment and let's you run Java Apps on your Windows.
Step 1:
Since J2ME appliations are made in JAVA langauge you need JRE (Java Runtime Environment) to make them run.
Step 2:
Download and install the KEmulator.
Step 3:
Open KEmulator and Go to Midlets to open Jar files.
That's it. You can now run any Java Mobile App or Game the same way.
