JavaTM Native Interface

Documentation Contents

Java^TM Native Interface (JNI) is a standard programming interface for writing Java native methods and embedding the Java^TM virtual machine into native applications. The primary goal is binary compatibility of native method libraries across all Java virtual machine implementations on a given platform.

The Java 2 SDK extends JNI to incorporate new features in the Java platform. The changes are driven by licensee and user comments.

The Java 2 SDK still supports the old native method interface (NMI), which was originally implemented in Java Development Kit (JDK^TM) 1.0. The old NMI is not part of the Java platform standard, and is not supported by the Java HotSpot^TM performance engine. Programmers are strongly encouraged to migrate their existing NMI code to the JNI.
