A CAP file utilizes the JAR file format, and contains a set of components that describe a Java language package. In addition to the components, the CAP file also contains the manifest file META-INF/MANIFEST.MF
. The manifest file provides additional human-readable information regarding the contents of the CAP file and the package that it represents. You can use this information to facilitate the distribution and processing of the CAP file.
The information in the manifest file is presented in name:value pairs. These name:value pairs are described in Table 7-1.

The properties in the manifest file include:
The names Java-Card-Applet-<n>-AID
and Java-Card-Applet-<n>-Name
refer to the same applet.
The converter assigns numbers for the Java-Card-Applet-<n>-NAME
and Java-Card-Applet-<n>-AID
names in sequential order, beginning with 1.
The names Java-Card-Imported-Package-<n>-AID
and Java-Card-Imported-Package-<n>-Version
refer to the same package.
The converter assigns numbers for the Java-Card-Imported-Package-<n>-AID
and Java-Card-Imported-Package-<n>-AID
names in sequential order, beginning with 1.
The following code sample illustrates the manifest file that the Converter generates when it converts package jcard.applications
. This package contains two applets, MyClass1 and MyClass2.
