Using the Java Native Interface

Integrate Java code with code written in other languages

Date:  17 Nov 2011 |Level: Intermediate |

1. Learn what JNI does

Understand the JNI framework's high-level concepts before putting them to use.

2. Get started using JNI

Start performing the two most common applications of JNI — calling C/C++ code from Java programs, and calling Java code from C/C++ programs — and learn how to avoid common JNI programming mistakes.

3. Use JNI on UNIX and Linux platforms

Find out how to leverage the JNI implementation in IBM's Java developer kit when you develop applications for AIX or Linux on POWER systems.

4. Leverage JNI on IBM i

Although the IBM JDK is optimized for IBM i, native methods written in IBM i integrated language environment (ILE) languages can access system-specific functions and APIs that aren't directly available in Java. Learn how JNI facilitates interoperability between the JVM and native methods. Then discover the advantages of moving a native method from the ILE to the IBM i Portable Application Solutions Environment (PASE).
