Java IOException jaas.conf（文件或目錄不存在）

我試圖使用JAAS創建一個登錄。當調用調用login()方法的方法時，我總是得到一個IOException。Java IOException jaas.conf（文件或目錄不存在）

，我叫login()方法的方法：

@FXML 
void anmeldenButton(ActionEvent event) throws LoginException { 
    name = tfbn.getText(); 
    password = tfpw.getText(); 

    try { 
     LoginContext lc = new LoginContext("LoginConfig", new CallbackHandler(name, password)); 
     lc.login(); 
    } catch (LoginException e) { 
     e.printStackTrace(); 
    } 
}

配置文件：

LoginConfig { 
    application.LoginModule required; 
};

錯誤：

阿有些部分是德國所以這裏翻譯： Datei =文件 Verzeichnis =目錄 nicht =不 vorhanden =存在（有） –

沒有人有解決這個問題的辦法嗎？我不能修復這個..
