Introduction

These release notes describe the development kit for the Java Card™ 3 Platform, Version 3.0.2, Classic Edition, binary release.

Java Card technology combines a subset of the Java™ programming language with a runtime environment optimized for smart cards and similar small-memory embedded devices. The goal of Java Card technology is to bring many of the benefits of the Java programming language to the resource-constrained world of smart cards. The Java Card API is compatible with international standards such as ISO 7816, and industry-specific standards such as Europay, Master Card, and Visa (EMV).

Java Card platform version 3.0.2 is the latest evolution of Java Card technology. This development kit is based on the Version 3.0.1 of the Java Card Specifications, which includes their errata sheets located here. The Java Card 3 Platform consists of versions 3.0 and 3.0.1 of the specifications and versions 3.0.1 and 3.0.2 of the development kit.

For the first time, the Java Card platform is available in two editions, both of which are backward compatible with previous versions and share key security features:

  • Classic Edition is based on an evolution of the Java Card Platform, Version 2.2.2, architecture. This edition targets more resource-constrained devices than the Connected Edition. Additional tools for the Classic Edition of the Java Card Platform, Version 3.0.1, are to be released at a later stage and are not covered by these notes. These release notes are for the Classic Edition.
  • Connected Edition contains a new architecture compared to the Java Card technology released in version 2.2.2, which is now known as the "Classic Edition." The Connected Edition enables the integration of smart cards within IP networks and web services architectures. To do so, it features a significantly enhanced runtime environment and virtual machine (VM), and it includes new network-oriented features, such as support for Java Servlet APIs and Java Card applets with extended and advanced capabilities.

Requirements

Platform

  • Operating system. This release is targeted for use on the Microsoft Windows XP SP2 operating system.

Required Software

The following software must be installed for the Java Card development kit to work:

  • Java Development Kit. The commercial version of Java Development Kit (JDK™) version 6, Update 10 or later is required. You can download the supported JDK software, JDK 6 Update 10 or later, from here.
  • GCC compiler. To build the VM, this release requires Minimal GNU for Windows (MinGW) version 5.1.4 or later. MinGW can be obtained from http://prdownloads.sourceforge.net/mingw. For information on MinGW go to http://www.mingw.org.
  • Apache Ant. Apache Ant version 1.6.5 or later is required. Latest version of Apache Ant can be obtained http://ant.apache.org.

For use with the samples, the Firefox browser is considered a trusted client by the RI. Firefox is available at http://www.mozilla.com.

Note — Do not install any software in a directory that contains a space in its name. For example, do not install software in any subdirectory of c:\program files because of the space in the program files element.

Installation

For a more thorough description of the installation, contents and use of the development kit, see Development User's Guide, Java Card Platform, Version 3.0.2, Classic Edition included in the download bundle for this release.

An automatic installer tool can be used to unpack the download file containing this release. During download, you can choose to let the installer tool unpack the download file into a directory of your choice on your system or you can save the download file itself to your system.

Note — Do not install development kit software in any directory that has a space in its name. For example, on a Windows platform, do not install software in the c:\program files directory, or any subdirectory of c:\program files, because the program files element contains a space.

To install the Java Card development kit and associated software, follow these steps:

  1. Install the JDK version 6, Update 10 or later. This JDK is available from here.
  2. Install Apache Ant version 1.6.5 or later. The latest version is available at: http://ant.apache.org/.
  3. Install the GCC compiler. The compiler Minimal GNU for Windows (MinGW), version 5.1.4 is required.  It is available at http://sourceforge.net/projects/mingw, while its installation information is at http://www.mingw.org.
  4. Download the Java Card development kit. Download and store the development kit Java Archive (JAR) file in a directory of your choice.
  5. Run the development kit installer or use the command line. Double click the JAR file on your system. If the JDK is installed correctly, the jar file is recognized as an executable jar and the automatic installer will launch to step you through the remainder of the installation process.

Alternatively, you can use the command line to unpack the JAR file using the following command:

java -jar Bundle-Filename
Where Bundle-Filename is the downloaded development kit JAR file.

By default, the development kit is installed in c:\jcdk3.0.2_ClassicEdition and its associated sub-directories. You can specify a different directory if you wish.

The directory c:\jcdk3.0.2_ClassicEdition (or the alternate directory you specify during installation) is referred to as JC_CLASSIC_HOME in these release notes. When the development kit installation is complete, JC_CLASSIC_HOME contains the following:

System Setup

Set System Variables and Paths
System variables and paths must be set before running the development kit. See the Development Kit User's Guide more details on how to set them. Note that if you choose to set the variables and paths each time you run the development kit rather than permanently in your system, you can place the appropriate commands in a batch file.

  • JAVA_HOME . You must set the JAVA_HOME system variable to the JDK root directory before running the development kit.
    • To temporarily set JAVA_HOME from the command line, enter the command: set JAVA_HOME=c:\ path before running the development kit. For example, if the Java platform software is stored in your c:\jdk6 directory, enter set JAVA_HOM E =c:\jdk6 before running the development kit.

  • JC_CLASSIC_HOME .  You must set the  JC__CLASSIC_HOME system variable to the directory in which the development kit is installed before running the development kit.  
    • To temporarily set JC_CLASSIC_HOME from the command line, enter the command: set JC_CLASSIC_HOME=c:\ path before running the development kit. For example, if the Java Card development kit is stored in your c:\ jcdk3.0.2_ClassicEdition directory, enter set JC_CLASSIC_HOM E =c:\ jcdk3.0.2_ClassicEdition before running the development kit. 
  • Apache Ant. You must set the ANT_HOME system variable to the Apache Ant directory before running the samples.
    • To temporarily set ANT_HOME from the command line, enter the command: set PATH=c:\ path before running the development kit. For example, if Apache Ant is stored in your c:\ ant\apache-ant1.6.5 directory, enter set ANT_HOM E = c:\ ant\apache-ant1.6.5 before running the development kit.
  • MinGW. You must set the path to the location of MinGW before running the development kit. Note that the path has to point to the \bin subdirectory of the MinGW installation directory where the gcc.exe file is located. 
    • To temporarily set the path to MinGW, enter the command set PATH=c:\ MinGW_path;%PATH% . For example, if MinGW is installed in c:\MinGW, enter the command set PATH=c:\MinGW\bin;%PATH% before running the development kit.

Configure the Java Card Runtime Environment for the Samples

Note that the Java Card RE ( cref) implementation is not optimized for memory or performance and, therefore, requires more memory than an actual optimized implementation on a card. To run the Java Card RE, you can use the default executable, cref.bat, using the command line as follows:

JC_CLASSIC_HOME\bin\ cref.bat

Uninstalling the Development Kit

To remove this development kit, an automatic uninstaller tool is provided in the directory Uninstaller. You can also completely remove the development kit by deleting the JC_CLASSIC_HOME directory along with all of its contents.
