根據網上內容搜尋以及不斷嘗試，總結出以下java使用jacob呼叫中控考勤機sdk方法

1、jacob-1.18版本

2、jdk1.732位（經過測試jacob目前只支援32位jdk，64位下報錯）；

3、將jacob.jar 放入專案 WEB-INFO/lib下匯入：

4、將jacob-1.18-x64.dll 放入32位 jdk/bin目錄下，我的是：C:\Program Files (x86)\Java\jdk1.7.0_79\bin；

5、將中控考勤機sdk 的dll檔案全部放入 c:\windows\syswow64 目錄下（我的是64位系統，32位的話沒測試，放入system32目錄下）；

6、執行cmd 註冊zkemkeeper.dll  --->regsvr32 c:\windows\syswow64\zkemkeeper.dll

7、成功後如下提示：

8、已經配置完畢，進行程式碼測試：

  //zkemkeeper.ZKEM.1 為zkemkeeper.dll 註冊成功後 在登錄檔可以檢視：HKEY_CLASSES_ROOT最下面

/**

public class ZkemSDK {
	
	private static ActiveXComponent zkem = new ActiveXComponent("zkemkeeper.ZKEM.1");
	
	/**
	 * 連結考勤機
	 * @param address 考勤機地址
	 * @param port 埠號
	 * @return 
	 */
	public boolean connect(String address,int port){
		boolean result = zkem.invoke("Connect_NET",address,port).getBoolean();
		return result;
	}
	/**
	 * 斷開考勤機連結
	 */
	public void disConnect(){
		zkem.invoke("Disconnect");
	}
}
 

/**

public class Main {
	
	public static void main(String[] args) {
		ZkemSDK sdk = new ZkemSDK();
		boolean  connFlag = sdk.connect("192.168.1.100", 4370);
		System.out.println("conn:"+connFlag);
	}
}

A、需要注意的是 jacob 我測試只能在32位jdk下使用；

B、如果main測試報錯，可以先把 考勤軟體安裝開啟 通過網路連線上考勤機之後再進行測試；
