Simulator Release Notes
1.1 Table of Contents
Java Card technology enables secure elements, such as smart cards and other tamper-resistant security chips to host applications called applets, which employ Java technology.
Java Card technology offers a secure and interoperable execution platform that can store and update multiple applications on a single resource constrained device, while retaining the highest certification levels and compatibility with standards. Java Card developers can build, test, and deploy applications and services rapidly and securely. This accelerated process reduces development costs, increases product differentiation, and enhances value to the customers.
The Java Card Development Kit is a suite of tools for designing implementations of Java Card technology and developing applets based on the Java Card Specifications. It is available as two independent downloads:
- The Java Card Development Kit Tools are used to convert and verify Java Card applications.
- The Java Card Development Kit Simulator offers a testing and debugging reference for Java Card applications. It includes a Java Card simulation environment and Eclipse plug-in.
Together, these two downloads provide a complete, stand-alone development environment in which applications written for the Java Card platform can be developed and tested.
These release notes describe the Java Card Development Kit Simulator version 3.1u1, which is based on version 3.1 of the Java Card Platform Specifications.
1.3 What's New
The following are new features and changes in the Java Card Development Kit Simulator, version 3.1u1:
- The Java Card plugin for Eclipse now supports all features of the latest Java Card Development Kit Tools and usability improvements for their integration. New features include:
- Support for extended CAP files
- Support for static resources in CAP files
- Support the target parameter of the converter for the following versions of the Java Card Platform Specifications: 3.0.4, 3.0.5, and 3.1.0
- New and improved management of CAP file configurations and the build process
- Persistence of CAP file configurations in files that can be directly used by the
convertertool in the command line
- Support for Java Card Development Kit Tools path configuration as an independent setting. This ensures that the plug-in can always be configured to access the latest tools bundle.
- Support for Java Card framework API debugging (source bundles only)
The following are new features and changes in the Java Card Development Kit Simulator, version 3.1:
