AWS上でGlassFishを構築しWebアプリを動かしたのですが、JSFからバッキングBEANに連動できていない。

前提・実現したいこと

勉強のため書籍に乗っているアプリをAWSで動作させています。
win10環境でアプリを構築し動作確認後にWARファイルを作成し、AWS上にFTPしてデプロイを行いました。
実行すると以下のエラーが発生しましたが、自分では暗礁に乗り上げたため対処方法をお指導お願いできないでしょうか。
Win10上では正常動作しますので環境の違いなのかとは思うですが。

・アプリ構築PC：
OS: win10
IDE: Apache NetBeans IDE 12.4
APサーバ：GlassFish Server 5.1.0
その他：
JDK:1.8
JSF 2.3
java EE version: Java EE 7 Web

・動作させたい環境：
AWS
インスタンス：t2.micro
OS: Amazon Linux 2 AMI
APサーバ： glassfish-4.1
