Install Java ME Development Kit
In order to start our journey of developing Java ME applications, we need to install the Java ME Development Kit (JDK). At the moment of this tutorial the Java ME SDK version is 3.4.
You can download it from here: http://www.oracle.com/technetwork/java/javame/javamobile/download/sdk/index.html, accept the License Agreement and download “Java ME SDK 3.4”: oracle-jmesdk-3-4-rr-win32-bin.exe.
Also download the “Java ME SDK 3.4 Plugins for Eclipse”: oracle-jmesdk-3-4-rr-eclipse-plugins.zip, since we will be using Eclipse in our development environment and we will use this plugin later.
Once the file Java ME SDK is downloaded double click on the file (i.e: oracle-jmesdk-3-4-rr-win32-bin.exe) to execute it and click Run.
When presented with the following screen, click select where you want to install the JDK, in my case I usually select the root of my D: Drive. You need to also set where you have installed the Java Development Kit. And click Next.
