的Tomcat JDBC領域登錄總是失敗

我有一個登錄爲例，其一個頁面，你去管理員或操作員登錄...的Tomcat JDBC領域登錄總是失敗

無論這一點，即使有正確的憑據，最後變成了一個servlet異常：登錄失敗...

這就是，希望你能幫助我：

你們都檢查/調試了什麼？用戶名/密碼是否到達bean？那麼這不是一個JSF問題。如果他們不是它是一個純粹的JSF問題，而不是tomcat/jdbc問題 – Kukeltje

我在MAC和Windows環境中嘗試了相同的設置，它的工作，所以，它可能是關於我的環境變量或東西...東真的不知道...... – Dezainer

我使用的是內置的功能到Tomcat做一個d我正在使用一個簡單的jsp，將表單的結果發佈到'j_security_check'。因此，用於用戶名的字段名是'j_username'，密碼是'j_password'（我使用的是Tomcat 8）。

<form action="j_security_check" method="POST"> 
    <table> 
     <tr> 
     <td><label for="username">Login:</label></td> 
     <td><input id="username" type="text" name="j_username" value=""></td> 
    </tr> 
    <tr> 
    <td><label for="password">Senha:</label></td> 
    <td><input id="password" type="password" name="j_password"></td> 
    <td><input type="submit" value="Login"/></td> 
    </tr> 
    </table> 
</form>

謝謝你的回答，但是，我正在攻讀大學考試，我真的需要這樣做。我在另一個環境中嘗試了相同的配置（即時使用LINUX並在MAC和WINDOWS上嘗試過），並且工作得很完美。所以我不知道發生了什麼...... – Dezainer
