I have a very strange situation here. I have made my application in JSF and it looks just great, however I am not quite sure about following: I want to have a hyperlink so that once I click on my book title I get to a page with all the details regarding that book. My code looks so far:
My class looks like this:
package com.century.rental;
import javax.ejb.Stateless;
import javax.persistence.*;
import java.util.List;
@Stateless
public class GameEJB {
@PersistenceContext(unitName = "PerUni")
private EntityManager em;
public List<Game> findGames() {
TypedQuery<Game> query = em.createNamedQuery("Game.findAll", Game.class);
return query.getResultList();
}
public List<Game> findGamesByTitle(String title) {
TypedQuery<Game> query = em.createNamedQuery("Game.findByTitle", Game.class);
query.setParameter("title", title);
return query.getResultList();
}
public Game find(Long id) {
return em.find(Game.class, id);
}
public Game createGame(Game game) {
em.persist(game);
System.out.print("game stored");
return game;
}
}
My controller class looks like this:
package com.century.rental;
import java.util.ArrayList;
import java.util.List;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean
@SessionScoped
public class GameController {
@EJB
private GameEJB gameEJB;
private Game game = new Game();
private String title = new String();
private List<Game> gameList = new ArrayList<Game>();
private List<Game> sgameList = new ArrayList<Game>();
public GameController() {
}
public String doCreateGame() {
gameEJB.createGame(game);
gameList = gameEJB.findGames();
game = new Game();
return "listGames.xhtml";
}
public Game getGame() {
return this.game;
}
public void setGame(Game game) {
this.game = game;
}
public List<Game> getGameList() {
gameList = gameEJB.findGames();
return gameList;
}
public void setGameList(List<Game> gameList) {
this.gameList = gameList;
}
public String searchGames() {
sgameList = gameEJB.findGamesByTitle(title);
return "resultsGames.xhtml";
}
public List<Game> getSgameList() {
return sgameList;
}
public void setSbookList(List<Game> sgameList) {
this.sgameList = sgameList;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
Entity:
package com.century.rental;
import java.util.Date;
import javax.persistence.*;
@Entity
@NamedQueries({
@NamedQuery(name = "Game.findAll", query = "SELECT g FROM Game g"),
@NamedQuery(name = "Game.findByTitle", query = "SELECT g FROM Game g WHERE g.title = :title")
})
public class Game extends Product {
@Basic(optional = false)
@Column(name = "DEVELOPER_STUDIO", nullable = false, length = 100)
private String developerStudio;
@Basic(optional = false)
@Column(name = "PLATFORM", nullable = false, length = 100)
private String platform;
public Game() {
}
public Game(String title, String description, String rating, Date releaseDate, String developerStudio, String platform) {
super(title, description, rating, releaseDate);
this.developerStudio = developerStudio;
this.platform = platform;
}
public String getDeveloperStudio() {
return developerStudio;
}
public void setDeveloperStudio(String developerStudio) {
this.developerStudio = developerStudio;
}
public String getPlatform() {
return platform;
}
public void setPlatform(String platform) {
this.platform = platform;
}
}
My HTML code looks like this:

Please, help me I am not quite sure how can I make a hyperlink to a specific book from a list of books( as shown in the code )
Thanks.
P.S.
My specific page specificGame, which is supposed to get values from a game that was clicked in listGames page.
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<h:head>
<title>List specific Game in Database</title>
<link rel="stylesheet" type="text/css" href="css/style.css" />
</h:head>
<h:body>
<f:view>
<h:form>
<h1><h:outputText value="List a specific Game in Database"/></h1>
<h:dataTable value="#{GameController.sGameList}" var="item" border="1">
<h:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<h:outputText value="#{item.name}"/>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Title"/>
</f:facet>
<h:outputText value="#{item.title}"/>
</h:column
</h:dataTable>
</h:form>
</f:view>
<br /><br />
<a href="newGame.faces">Add New</a> -OR- <a href="index.faces">Go to Main Page</a>
</h:body>
</html>
Now when I click on a title from the list of games on page list Games I would be redirected to specific Game page which is supposed to look like this: https://i.stack.imgur.com/OHmdp.png
populated by all the values from the particular game.
