The first time I tried to build a J2ME (Java2 Mobile Edition) application, I had a hard time choosing the right tools.

Here’s a tiny guide to setup a development environment for J2ME (under Windows) :

• Install a JVM (Java Virtual Machine). I used jre_1.5.0.09 from http://java.sun.com/
• Install Eclipse (I used version 3.1.2) from http://www.eclipse.com/
• Install Nokia Prototype SDK from http://www.forum.nokia.com/
• Install EclipseME: Open eclipse and go to Menu->Help->Software Updates->Find and Install -> New remote site then enter in the address field http://eclipseme.org/updates

Nokia Prototype SDK is called a “Wireless Toolkit”, and is only available under Windows.

If you run Linux, you’ll have to choose another Wireless toolkit as “Sun Wireless Toolkit” (Man google)
