关于C调用java的错误.

[ltopfly]

请问:在VC里执行如下的C程序来调用,为什么会产生错误:
/***********
Deleting intermediate files and output files for project 'test1 - Win32 Debug'.
--------------------Configuration: test1 - Win32 Debug--------------------

Debug/test1.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

test1.exe - 2 error(s), 0 warning(s)
***********/

test.c如下:
////////////////开始
#include <jni.h>

#ifdef _WIN32
#define PATH_SEPARATOR ';'
#else
#define PATH_SEPARATOR ':'
#endif

int main()
{
JavaVMOption options[1];
JNIEnv *env;
JavaVM *jvm;
JavaVMInitArgs vm_args;
long status;
jclass cls;
jmethodID mid;
jint square;
jboolean not;


options[0].optionString = "-Djava.class.path=.";
//memset(&vm_args, 0, sizeof(vm_args));
vm_args.version = JNI_VERSION_1_4;
vm_args.nOptions = 1;
vm_args.options = options;
status = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);

if (status != JNI_ERR)
{
cls = (*env)->FindClass(env, "Sample2");
if(cls !=0)
{
mid = (*env)->GetStaticMethodID(env, cls, "intMethod", "(I)I");
if(mid !=0)
{
square = (*env)->CallStaticIntMethod(env, cls, mid, 5);
printf("Result of intMethod: %d\n", square);
}

mid = (*env)->GetStaticMethodID(env, cls, "booleanMethod", "(Z)Z");
if(mid !=0)
{
not = (*env)->CallStaticBooleanMethod(env, cls, mid, 1);
printf("Result of booleanMethod: %d\n", not);
}
}

(*jvm)->DestroyJavaVM(jvm);
return 0;
}
else
return -1;
}
///////////结束

java类
Sample2.java
/////////////开始
public class Sample2
{
public static int intMethod(int n) {
return n*n;
}

public static boolean booleanMethod(boolean bool) {
return !bool;
}
}
//////////结束

补充一下:
我在VC里面Include Files里加了\JDK1.4\INCLUDE和\JDK1.4\INCLUDE\WIN32以及在Library Files里加了\JDK1.4\LIB的,但在VC里编译可以通过,但在build时就会出现以上错误,好象是说创建java虚拟机不成功,请各位帮帮忙!在此先行谢过!
