Generating Application Modules From Classic Applets
Developers use the Normalizer to generate application modules for Java Card 3 Platform classic applets they are creating or from classic applets created for previous versions of the Java Card platform. These application modules contain CAP files and are downloadable on both the Java Card 3 platform Classic Edition and Connected Edition smart cards.
The output from the tool is a classic module that contains the class files, the CAP components of the CAP file, SIO proxies for classic SIOs (if required), and associated classic application descriptors. The input to the tool must be classic CAP files and associated export (EXP) files. If the input files are not classic CAP files, the normalization fails.
