Gluegen
Encyclopedia
GlueGen is a Java
tool which automatically generates the Java and Java Native Interface
(JNI) code needed to call C
libraries from Java code. It reads in ANSI C
header files and GlueGen configuration files, and emits C code. As JNI can be complex, Gluegen simplifies the process of binding Java to C native libraries.
It was originally developed for Java OpenGL
(JOGL), a Java OpenGL
library, although the project has since been separated so it can be used with other libraries. As of 2010, it is also used in Java OpenAL
(JOAL), which allows Java code to access OpenAL
libraries.

Java (programming language)
Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities...

Java Native Interface
The Java Native Interface is a programming framework that enables Java code running in a Java Virtual Machine to call and to be called by native applications and libraries written in other languages such as C, C++ and assembly.-Purpose and features:JNI enables one to write native methods to...
