私はServletメールとhtml-form：を送信するシンプルなものを持っています

<!DOCTYPE html>
<html>
 <head>
  <meta charset="utf-8">
  <title>A form</title>
 </head>
 <body>
 <form action="feedback" method="post">

  <!-- Simple text field -->
 <label for="name">Name </label>
 <input type="text" name="name"/>
 <br/>

  <!-- Email -->
 <label for="email">Email </label>
 <input type="email" name="email"/>
 <br/>


  <!-- Textarea -->
 <label for="description">Description </label>
 <textarea  name="description" cols="50" rows="5">Type your comment here</textarea>
 <br/>


 <input type="submit" name="submit" value="Send Request"/>
 </form>
 </body>
</html>

web.xmlフォルダーで、サーブレットを登録してマップしました。しかし、送信ボタンを押すと、次のようになります。

HTTPエラー404

/feedbackへのアクセスに問題があります。理由：

NOT_FOUND

まだ私の問題はどこにありますか？

あなたweb.xmlから見ると、URLパターンに問題があるように見えるので、それだけで404エラーが発生します。またはに変更<form action="feedback" method="post">する<form action="/wunderapps_mail_service/mail" method="post">か、web.xmlを変更することもできます。

<servlet-mapping>
    <servlet-name>FeedbackServlet</servlet-name>
    <url-pattern>/feedback</url-pattern>
