Build requirements

Install a JAVA compiler and ANT:

$ sudo apt-get install default-jdk ant

Download the Javacard SDKs into the (empty) directory oracle_javacard_sdks

$ git submodule update --init --recursive

There is also another component "ant-javacard.jar", which is automatically downloaded during the build process.

Building CAP files

The build process is started by calling ANT

$ ant
