PURPOSE: A method and a system for generating a binary code executable on a mobile communication terminal embedded with a wireless Internet platform using Java are provided to make a downloadable component to emerge from a VM(Virtual Machine) method, which is constraint for enhancement of speed-up, while stability of the Java is kept. CONSTITUTION: A Java bytecode analyzer extracts a structure of a class by analyzing an input class file and generates a C++ code by using analysis information. A C/C++ code generator generates the C++ source code mapping the same structure based on class analysis information. A runtime type information analyzer has a data type information analysis function for mapping a variable type and function corresponding to a Java variable type used in the class and a case converted into the C++. An exception handler generator maps a Java exception handing function to a C++ exception handling function. An inline function generator classifies the function to perform an inline process according to configuration of a member function and implements an inline function for generation of the C++ code.
