將NetBeans中的HTML與MSAcess連接起來

我有一個HTML頁面，其中新用戶被添加到數據庫，我通過JDBC-ODBC和Servlets完成了MS-Access連接。我沒有錯誤，但是這些值沒有保存在數據庫中。將NetBeans中的HTML與MSAcess連接起來

******* HTML文件*****

<html> 
    <head> 
     <title>TODO supply a title</title> 
     <meta charset="UTF-8"> 
     <meta name="viewport" content="width=device-width, initial-scale=1.0"> 
    </head> 
    <body> 
     <div> 
      <center><h1>login page</h1></center> 
      <form action="Serve" method="get"> 
      Username: <input type="text" name="username"><br> 
      Password: <input type="text" name="password"><br> 
      <button> Login</button> 
      </form> 
     </div> 
    </body> 
</html>

*** JDBC-ODBC FILE ****

問題是您從請求對象中獲取了錯誤的參數。

試試這個：

s.s="insert into Table1 values("+request.getParameter("username")+","+request.getParameter("password")+")";
