Unfortunately, all the values I entered are not displayed on the website, does anyone have an idea why?
On picture 1 I have screenshotted the output.

I got it. The ProductDemo.java must be in a managed bean and the value in the xhtml didnt match with the java class

So, i have this piece of code, which basically performs CRUD on a database and displays the results in a <h:dataTable>. The problem is, my code is able to generate an edit action, when I provide a fixed ArrayList. But, if i populate the ArrayList from a database, the rendered property does not provide an editable option from the form. I am able to perform delete functionality, so it's not a matter of the object not being read properly in the action method's parameter. In short, the rendered attribute doesn't work when my data source is a table from a database.
Here's the page:

This question already has answers here:
Creating master-detail pages for entities, how to link them and which bean scope to choose
(2 answers)
Closed 7 years ago.
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;
}
}

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.

</h:column
</h:dataTable>
</h:form>
</f:view>
<br /><br />
Add New -OR- Go to Main Page
</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: http://i.stack.imgur.com/OHmdp.png
populated by all the values from the particular game.
Try to change the column title in listGames.xhtml to :
<h:column>
<f:facet name="header">
<h:outputText value="Title"/>
</f:facet>
<h:commandLink value="#{item.title}" action="#{gameController.searchGames(item.title)}" />
</h:column>
Then, adapt the action method in the backing bean to :
public String searchGames(String tit) {
sgameList = gameEJB.findGamesByTitle(tit);
return "resultsGames.xhtml";
}

Thank's :)
Perhaps try modifying it slightly to be more like the Primefaces showcase example. For example, try something like this:
...
<h:form id="form">
...
<p:dataTable value="#{diplome.getAllDiplome()}" var="d" paginator="true" rows="10"
rowKey="diplome.idDiplome" selection="#{diplome.selectedDiplome}" selectionMode="single">
<p:ajax event="rowSelect" update=":form:display" oncomplete="PF('diplomeDialog').show()" />
...
</p:dataTable>
...
<p:dialog header="Diplome Detail" widgetVar="diplomeDialog" resizable="false"
width="200" showEffect="explode" hideEffect="explode">
<h:panelGrid id="display">
...
</h:panelGrid>
</p:dialog>
</h:form>
...
I can't test this right now, but it seems like it should work since it is essentially the same as the showcase's example.
I am able to print the data from a JSF home page in form of table. But the issue is that it is able to print only one entry at a time.What if I enter more names i.e. name and password without using Database. Please find managed bean and format of table is taken by tutorial.

City | School | Add/Remove
Київ "textbox" "checkbox"
Харків "textbox" "checkbox"
Cities are populated from City class
public class UkrCity {
private List<A> ukrCities;
public List<A> getUkrCities() {
return ukrCities;
}
public void setUkrCities(final List<A> ukrCities) {
this.ukrCities= ukrCities;
}
private void allCities() {
//add all cities in a list
ukrCities.add("Київ");
ukrCities.add("Харків");
}
}
how to show ukrcities on xhtml page under City and blank textbox and checkbox under school and add/remove tav.
thank you
sorry my bad english.
I have refactored your code. Here is the UkrCity Class.
package com.example;
import java.io.Serializable;
public class UkrCity implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private String name;
public UkrCity(String name) {
this.setName(name);
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Here is the backing bean
package com.example;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Arrays;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
#ManagedBean
#SessionScoped
public class TableBean implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private ArrayList<UkrCity> cities = new ArrayList<UkrCity>(Arrays.asList(new UkrCity("Київ"),new UkrCity("Харків") ));
public ArrayList<UkrCity> getCities() {
return cities;
}
}
