让别人用C帮我写的一个DLL，用来传递一个进程名称，然后杀掉和进程名字相同的进程。我在CMD里面用javac的方式运行

关闭notepad.exe成功能够关闭成功。
Process_.java的代码为：public class Process_ {   
    static
    {
       System.loadLibrary( "Process_" ); 
    }  
    public native static int TerminateProcess(String name);  
    
public static void main(String[] args){ 
System.out.println("======"); 
System.out.println( "start "); 
Process_ pro = new Process_();
int n = Process_.TerminateProcess("notepad.exe");
if (n==0)
{
System.out.println( "关闭notepad.exe成功"); 
}
else
System.out.println( "关闭notepad.exe失败"); 
}  
}  
可把这段代码拿到MyEclipse下面，点右键Run as --》 Java Application的时候报错。
Exception in thread "main" java.lang.UnsatisfiedLinkError:
com.up.load.Process_.TerminateProcess(Ljava/lang/String;)I我把Process_.dll放到librarypath下面去了，现在好像是找不到TerminateProcess这个方法，而不是找不到Process_这个类。望高手解答，谢谢。
