Abstract: A method includes executing an application of a scripting language. The application of the scripting language uses first and second packages of an application programming interface (API). The first and second packages extend to each other. The method includes, from a class of the first package, calling and executing first native code of the API to implement a function of a method of the class of the first package. The first native code is in a programming language different from the scripting language. The executing the first native code of the API includes calling a method of a class of the second package. The called method of the class of the second package is executed using a virtual machine of the scripting language. The application of the scripting language may be a Java card application, and the programming language may be a C programming language.
