用jni 初始化jvm

int _tmain(int argc, _TCHAR* argv[])
{ 
  int res;
  JavaVM *jvm;
  JNIEnv *env;
  JavaVMInitArgs vm_args;

  /*设置初始化参数*/
  JavaVMOption options[3];
  options[0].optionString = "-Djava.compiler=NONE";
  options[1].optionString = "-Djava.class.path=.;";
  options[2].optionString = "-verbose:jni";

  vm_args.version = JNI_VERSION_1_4;//版本号设置不能漏
  vm_args.nOptions = 3;
  vm_args.options = options;
  vm_args.ignoreUnrecognized= JNI_TRUE;
 
 
  res = JNI_CreateJavaVM(&jvm,(void**)&env, &vm_args);
  if (res < 0) {
     fprintf(stderr,"Can't create Java VM\n");
     exit(1);
  }
 
 
 fprintf(stdout,"Java VM destory.\n");
  return 0;
}

这个例子也是摘自网上的 ,只不过是调试通过了.

但是为什么一直提示找不到 jvm.dll 呢
