This tutorial describes and demonstrates the basic and most commonly used techniques of the Java Native Interface -- calling C or C++ code from Java programs, and calling Java code from C or C++ programs -- to help you develop your own JNI solutions quickly and efficiently. The Java Native Interface (JNI) is a native programming interface that is part of the Java Software Development Kit (SDK). JNI lets Java code use code and code libraries written in other languages, such as C and C++. The Invocation API, which is part of JNI, can be used to embed a Java virtual machine (JVM) into native applications, thereby allowing programmers to call Java code from within native code. This tutorial deals with the two most common applications of JNI: calling C/C++ code from Java programs, and calling Java code from C/C++ programs. We'll cover both the essentials of the Java Native Interface and some of the more advanced programming challenges that can arise.... The section on Advanced topics is separate from the more basic step-by-step introduction to JNI. Beginning Java programmers may benefit from taking the first two parts of the tutorial now and returning to the advanced topics at a later time. See Resources for a listing of tutorials, articles, and other references that expand upon the material presented here.
