這個是java撈資料程式....
其實我是想問各位大大，要怎麼用寫好的撈資料程式從登入驗證帳密→超連結→超連結→超連接→到要撈的資料

<html><head><title></title><meta http-equiv="Content-Type" content="text/html; charset=big5"></head>    <body>                            <form name="form3" method="post">          <input type="hidden" name="id" value="-1">          <input type="hidden" name="pwd" value="1wEWKwrCP83reK7KcQyql3XhOLkd228Rid9mLgZb+9EGNQYPZ1dFxF1VcbSD9q7e">          <input type="hidden" name="submit1" value="login">                       </form> <script>       document.form3.action="http://sis.hust.edu.tw/face/login/login2.asp";       document.form3.submit(); </script>    </body></html>
Process completed.
這是我用撈資料程式撈系統登入的地方的訊息
但是我不知道怎麼利用解析好的ID、PW的value來進行驗證，然後呼叫下個點選的超連結按鈕....
如果知道的大大請給我個解決答案....小弟會非常感謝你的.....

你的問題是 Android? 還是 JSP?
