5	Modify help.js file as explained below.
6	Modify pom.xml as explained below.
7	Modify home.xhtml as explained below. Keep rest of the files unchanged.
8	Compile and run the application to make sure business logic is working as per the requirements.
9	Finally, build the application in the form of war file and deploy it in Apache Tomcat Webserver.
10	Launch your web application using appropriate URL as explained below in the last step.

すべての変更を完了したら、JSF-最初のアプリケーションの章で行ったようにアプリケーションをコンパイルして実行します。すべてがアプリケーションで問題ない場合、次の結果が生成されます。
