javah.exe

A tool used by JNI programmers. It takes a class file that declares some abstract native methods and creates a C, yes C, header file containing source code for C-style method signatures for the native methods you have yet to write in C, C++ or assembler.

Sun’s JDK Tool Guide to javah.exe : available:

on the web at java.sun.com
in the current JDK 1.6.0_07 or in the beta JDK 1.6.0_10 on your local J: drive.

It works much like java.exe except instead of running the program it examines the compiled class file to produce C source code. e.g.

javah.exe -jni -o PCClock.h com.mindprod.Clock.PCClock

You must specify the fully qualified class name, without the .class extension. The -o option lets you specify the name of the generated output C source code header file.
