Java™ Native Interface

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.

JNI FAQ
A shared stub is a single JNI native method that can dispatch to many C functions. You can download the complete example from here:

For Windows, download jnistb10.zip (38K)
For Solaris, download either jnistb10.tar.Z (60K) or jnistb10.tar.gz (27K).

JNI Enhancements will report further enhancements to this technology as they are added.
