JSFのManagedBeanがnullで返ってきてしまう

こんにちは。
次の仕事でJavaのJSFを使用する為、こちらのサイトを使って図書検索システムの作成を行っていますが、以下のエラーを出してしまい、検索結果が表示出来ないので、皆様からご教示を頂きたく、質問させて頂きました。
netbeansを使って、JSFにMySQLを接続するには、どうすればよろしいでしょうか。

#開発環境
OS:Windows10 home
Java:15.0.2、jre1.8.0
ドライバ:mysql-connector-java-8.0.25.jar
IDE:Netbeans
DB:MySQL

#試したこと
①MySQLの接続確認と、DBとテーブルの指定を追加
②ソースコードの見直し
③ライブラリにMySQLのJDBCドライバの指定(mysql-connector-java-8.0.25-bin.jar)
④データベースからのエンティティクラスの作成

以上、拙い質問で大変恐縮ですが、宜しくお願い致します。
