NetBeans Java ME CDC Development Quick Start Guide
Introduction
Connected Device Configuration (CDC) applications are designed to run on mobile and
embedded devices with at least 2MB of memory. This configuration supports a more feature-rich
JVM than MIDP-based mobile phones, which typically have much less memory and use the
Connected Limited Device Configuration (CLDC). This tutorial shows you how to use NetBeans
IDE to create a Java Platform, Micro Edition (Java ME platform) CDC application. We show you how
to create a Java ME CDC project that displays a simple form in a device emulator for the three
available CDC profiles. This document is designed to get you creating applications as quickly as
possible.
Note:
If you are using NetBeans IDE 6.9, 7.0, or 7.1, refer to the NetBeans 6.9, 7.0, or 7.1 Java ME
CDC Development Quick Start Guide.

Requirements
To complete this tutorial, you need the following software and resources:
Software or Resource Version Required
NetBeans IDE with Java ME Version 7.2
Java Development Kit (JDK) Version 6 or version 7
Supported CDC Emulator Platforms
The IDE installer for the Windows operating system includes the Java ME SDK 3.0.5 which allows
you to develop CDC applications. Note that different CDC emulator platforms support different
development profiles. The main development profiles and the emulators that support them are:
Personal Basis Profile (Sun Java ME SDK) supports an application development
framework for mobile and embedded devices (more info)
Personal Profile (Nokia) is the most popular profile for smartphone development (more
info)
Note: Instructions for adding the Nokia Series 80 Platform SDK for Symbian OS, Java
and Personal Profile emulator platform are listed in the NetBeans CDC Platform
Emulator Setup Guide.
In the following sections we create a CDC project using each available profile and also use the
IDE's GUI builder in the Personal and AGUI profile applications to enhance the User Interface.

Creating a New CDC Application - Personal Basis Profile
Here we create a CDC Application for the Personal Basis Profile (PBP) 1.1 Profile using the Java
ME SDK 3.0.5.
1. Choose File > New Project (Ctrl+Shift+N) from the main window.
2. From Categories, select Java ME. From Projects, select CDC Application. Click
Next.
3. In the Name and Location page, name the project newcdc and leave the Create Main
Class checkbox checked. Click Next.
4. In the Select Platform page, use the drop-down menus to choose CDC Java(TM)
Platform Micro Edition SDK 3.0.5 for the Java Platform and
DefaultCdcPbpPhone1 as the Device. Leave the Profile settings as PBP-1.1 like
shown in the following picture.
5. Click Finish. The IDE creates the new application and opens the main class form.
6. In the Source view, find g.drawString("Hello, World!", 80, 50); and add
the word Java so that it reads Hello, Java World!
7. To build the project, choose Run > Build Project from the main toolbar.
8. Choose Run > Run Project from the main toolbar to run your project.
The project launches in the emulator and and displays the modified "Hello World!"
message.

You can also debug the project and create tests for CDC projects using the JUnit framework.
Creating a New CDC Application - Personal Profile
Here we create an applet for the Personal Profile using the Nokia Series 80 Platform SDK for
Symbian OS, for Java, Personal Profile. The Sony Ericsson platform also supports the Personal
Profile.
1. Choose File > New Project (Ctrl+Shift+N). Under Categories, select Java
ME. Under Projects, select the CDC Application template. Click Next.
2. Name the project S80cdcApplication and specify a location for the project on your
computer. Leave the Create Main Class check box selected. Click Next.
3. In the Select Platform Page, choose the Nokia S80 Platform.

4. Click Finish. The IDE creates a new application and opens the main class form in the GUI
Builder, as shown in the following figure. Click on Source to see the source code for the
applet.
Note: The generated code is based on the profile. Here the main class is derived
from java.awt.Frame.
Creating the Application Interface Using the GUI Builder
You can use the GUI Builder in the same way you use it for regular J2SE development. In the GUI
Builder, right-click the Main.java form and choose Set Layout > Free Design. Then drag
and drop components from the Palette window into the Design Area of the GUI Builder.
Note: Make sure you only use AWT components in your form. Since all the Nokia Series 80
devices support the Personal Profile, only AWT widgets are available.
For more information on using the IDE's GUI Builder, see the Java GUI Applications Learning Trail.
When you are done, right-click the project in the Projects window and choose Run from the popup

menu. Your application should be displayed in the device emulator.
You can now run the device in the emulator.
You can also debug the project, and create and debug tests using the JUnit framework.
