Example usage of the Java Native Interface (JNI)

Description

The goal of this mini-project is to illustrate the usage of the Java Native Interface (JNI). A Makefile is used to compile the project so that every details about the building phases are exposed:

1. Compilation of the libexample.so library
2. Compilation of the JNIExample java class
3. Generation of the header containing native methods from the JNIExample class
4. Compilation of the native methods binding the function exposed in libexample to the Java language

This project as been tested on GNU/Linux but it should be usable without modification on any POSIX system where a C compiler, GNU Make and a Java SDK are installed.

Usage

Compile with make, run with make run.

Troobleshooting

• Ensure you have a working C compiler.
• Ensure the various binaries distributed with the Java SDK are in your PATH.
• Set JAVA_HOME to the locatation of the Java SDK.
