关于java中调用C＋＋组件的问题，还请各位大虾指教

现在有一个C＋＋写的RemoteRobot.dll，我的代码如下：
package com.ttt;

public class TestDll {

static

{
System.loadLibrary("RemoteRobot.RobotControl");
}

public native static boolean Connect(String s, int i);
public native static boolean Disconnect();

public static void main(String[] args)
{
TestDll test = new TestDll();
test.Connect("127.0.0.1",800);
}
}

运行时出现如下错误：
Could not find D:/jakarta-tomcat-4.0.1/jakarta-tomcat-4.0.1/lib/jasper-compiler.jar to copy to WebApp <Default WebApp>; file is defined as element of library ser
D:/jakarta-tomcat-4.0.1/jakarta-tomcat-4.0.1/lib/jasper-compiler.jar (The system cannot find the file specified)


请问是什么原因啊，谢了。
