how can I create an application for mobile phone with .JAR extension?

Question

I Want to create a photo dictionary with .jar extension for mobile phones,what is the right tool or language for this purpose ?

Answer 1

I suspect that you would want to write a so called MIDlet using Java ME.

The proper tools include

1. The Java SDK
2. Eclipse together with a proper plugin such as EclipseME (or another compliant IDE)
3. The Sun Wireless Toolkit (WTK) which among other things contains an emulator)

A good step-by-step introduction to writing your first MIDlet can be found here:
