javah

/usr/java/bin/javah [options] classes | files

Solaris only. Generate C header and/or source files for implementing native methods. The generated .h file defines a structure whose members parallel those of the corresponding Java class.

The header filename is derived from the corresponding Java class. If the class is inside a package, the package name is prepended to the filename and the structure name, separated by an underscore.

Note: the Java Native Interface (JNI) does not require header or stub files. Use the -jni option to create function prototypes for JNI native methods.
