標頭檔案宣告：

  /* Header for class com_service_InvocationService */
#include "jni.h"
#ifndef _Included_com_service_InvocationService
#define _Included_com_service_InvocationService
#ifdef __cplusplus
extern "C" {
#endif
/*
 * Class:     com_service_InvocationService
 * Method:    execute
 */
JNIEXPORT void JNICALL Java_com_service_InvocationService_execute
  (JNIEnv *, jobject, jstring);
{
   //在這裡新增任意程式碼
}
 

cpp檔案，實現

 #include <iostream.h>
 #include <string.h>
 #include "com_service_InvocationService.h"

JNIEXPORT void JNICALL Java_com_service_InvocationService_execute
  (JNIEnv *, jobject, jstring)
{
     //在這裡新增任意程式碼
	return;
}
