佈局：

C++ ------------>lib，檔案dms_lib.cpp

C++ ------------>JNI C++，檔案dms_jni.cpp

JAVA ------------>JNI JAVA，檔案dms.java

通過以下命令，可以生成java的jni標頭檔案：javac dms.java && javah dms

/**  * file: dms.java * {@hide} */public class dms{    // can't instantiate this class    private dms()    {    }    /**     * start the upnp device.         */
 
    public static native int startDevice();    /**     * stop the upnp device.     */    public static native int stopDevice();}

/* DO NOT EDIT THIS FILE - it is machine generated */
 
#include <jni.h>/* Header for class dms */#ifndef _Included_dms#define _Included_dms#ifdef __cplusplusextern "C" {#endif/* * Class:     dms * Method:    startDevice * Signature: ()I */JNIEXPORT jint JNICALL Java_dms_startDevice  (JNIEnv *, jclass);/* * Class:     dms * Method:    stopDevice * Signature: ()I */JNIEXPORT jint JNICALL Java_dms_stopDevice  (JNIEnv *, jclass);#ifdef __cplusplus}#endif#endif

dms_lib.h:

#ifndef DMS_LIB_H#define DMS_LIB_H#include "Neptune.h"#include "Platinum.h"class dms{    private dms();        private PLT_UPnP m_upnp;    private PLT_DeviceHostReference m_device;        public void start_dms();    public void stop_dms();}    #endif //DMS_LIB_H
