===== 5.2 Containment in a JAR File =====

As described in [[4.1.3_JAR File Container| Section 4.1.3, JAR File Container]], Java Card CAP files are contained in a JAR file. If an export file is also stored in a JAR file, it must also be located in a directory called **javacard** that is a subdirectory of the package's directory. For example, the **framework.exp** file would be located in the subdirectory **javacard**/framework/**javacard**.
