I need answer for 3 questions. You do not have to write code. You can give me just answer and maybe just some corrections in code. I think something is wrong with index.xhtml or template.xhtml-why the information dont want to display on the web: Welcome message, 2 links and the message on the bottom of the page.- why JavaBean doesnt work?- do I have to use servlets and why? Technology usedJava, JSF, I think GlassFish, virtual machine, Maven. Text of assignment: Residents of the Nowhere township are tired of waiting for Craig to set a classified listing service for their town, and have contract you to create Bubbas List. To provide a common look and feel to the website, prepare a page template. At the top of the page include a Bubbas List, and at the bottom of the page include a standard disclaimer reminding user of the dangers of homemade whiskey. Also include a style sheet that sets the font-family for the body of the document to Arial. The first page of your application should be a welcome page written with JSF. This page should be built from the page template. In the body of the page include two links. The first link should lead to the listing submission page. The second link should lead to the listings summary page. The listing submissions page allows users to enter a new listing on the site. The complete listing includes a title, the name of the poster, a phone number to call, and a block of text completely describing what is being offered. When the users submits the submission form the system should add their listing to the inventory, and then they should be redirected to the detailed listing page. The detailed listing page should present all the information about the listing in an easy to read format. At the bottom of the page include a link back to the summary page. The main listing page should present a summary of the listings currently posted to the site. Each summary should present the title of the listing, and the phone number to call to learn more about the listing. The title of the listing should be a hyper-link, which will take the user to the appropriate detailed listing page. Build this page as a JSF page, and use the template to display the header and disclaimer.Attachments: exercise3.zip
