dllwrapper.c

jni调用例子 可以调用测试 java jni vc 6

#include "jnisample_JNIWrapper.h"
#include <windows.h>

typedef BOOL (*FUNCHELLO)();

JNIEXPORT void JNICALL Java_jnisample_JNIWrapper__1dll_1Hello(JNIEnv * jenv, jclass jcls)
{
    HANDLE hDll;
    FUNCHELLO fnHello;

    hDll = LoadLibrary("HelloDll.dll");
    if (hDll) {
        fnHello = (FUNCHELLO)GetProcAddress(hDll, "_Hello@0");
		if (fnHello) fnHello();
        FreeLibrary(hDll);
    }
}
