Developing Java Card 3 Platform Applications

This chapter provides a brief description of the activities and development kit tools involved in developing applications for the Java Card 3 platform. Whether you use the development kit tools or the NetBeans IDE as your development environment, these same, basic activities apply. If you are enabling classic applets to run on Connected Edition and Classic Edition cards, see Chapter 9.

##

Development Steps

The steps described in FIGURE 3-1 illustrate the sequence of activities completed by a developer when creating an application for the Java Card 3 platform. See the Application Programming Notes, Java Card Platform, Version 3.0.1, Connected Edition for additional, advanced information not provided in this guide about creating applications for the Java Card 3 platform.

FIGURE 3-1 Java Card 3 Platform Application Development

1. Source files - Write the source code and create the descriptor files.

The development kit also provides sample application source code that developers can use in creating custom applications. See Chapter 4 for a description of the samples provided in the development kit.

2. Compile/build - Compile the source code.

See Chapter 6 for a description of using the Java Card 3 platform Compiler tool (`javacardc.bat`) as a stand-alone application.

3. Packager - Package the compiled source code.

See Chapter 7 for a description of using the Packager tool to create and validate application modules.

4. Off-Card Installer - Load the application and create instances on the card by using the Installer tool.

See Chapter 8 for a description of using the Off-Card Installer (Installer) tool and the associated on-card installer used to load an application module onto the card, create an instance of an application, delete (deactivate) an instance of an application, remove a module or application from the card, and display information about loaded applications and instances.

5. Browser/Client - Access the application on the card by using a client (browser or APDU tool).

See Chapter 10 for description of using the APDU tool to display command and response APDU commands on the console.
