PrimeFaces QuickStart Tutorial-Part1

PrimeFaces is an open source component library for JSF 2.0 with morethan 100 rich components. PrimeFaces is far better than many other JSF component libraries because of the following reasons:

    1. Rich set of UI components (DataTable, AutoComplete, HtmlEditor, Charts etc).
    2. No extra xml configuration is required and there is no required dependencies.
    3. Built-in Ajax based on standard JSF 2.0 Ajax APIs.
    4. Skinning Framework with 25+ built-in themes.
    5. Awesome documentation with code examples.

Let us build a sample application using PrimeFaces with the following features:
1. A Login screen which accepts username and password and authenticate the user.
2. Upon successful login user will be shown a User Search screen. Users can search for users by their name.The search results will be displayed in a DataTable with pagination, sorting and filtering support.
3. Upon clicking on a row the user details will be displayed in a form.

First download JSF 2 jars from http://javaserverfaces.java.net/download.html
Place the jsf-api-2.0.3.jar, jsf-impl-2.0.3.jar and jstl-1.0.2.jar jars in WEB-INF/lib folder.
Download PrimeFaces from http://www.primefaces.org/downloads.html.
Place primefaces-2.2.RC2.jar in WEB-INF/lib folder.

Configure FacesServlet in web.xml

<web-app version="2.5">
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" >
    
    
        index.jsp
    
        
    
        Faces Servlet
        javax.faces.webapp.FacesServlet
        1
    

    
        Faces Servlet
        *.jsf
    
    
</web-app>

Create faces-config.xml in WEB-INF folder.


    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
    version="2.0">

Welcome page index.jsp just forwards to login screen.

Create login.xhtml page.

    
<html xmlns="http://www.w3c.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:p="http://primefaces.prime.com.tr/ui">

    

    

            
            
                
                
                
                
                
            
        
    
    
    

</html>

You can get the blusky theme from PrimeFaces bundle.

Create home.xhtml which contains UserSearchForm, Results dataTable and UserDetails Panel.

Create User.java domain class.

package com.primefaces.sample;

import java.util.Date;

public class User
{
    private Integer userId;
    private String username;
    private String emailId;
    private String phone;
    private Date dob;
    private String gender;
    private String address;
    
    public User()
    {}
    public User(Integer userId, String username, String emailId, String phone,
            Date dob, String gender, String address)
    {
        this.userId = userId;
        this.username = username;
        this.emailId = emailId;
        this.phone = phone;
        this.dob = dob;
        this.gender = gender;
        this.address = address;
    }
    //setter and getters    
}

Create UserService.java which acts as a mock database table.

package com.primefaces.sample;

import java.util.ArrayList;
import java.util.Collection;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

        USERS_TABLE.put(11, new User(11, "Rogermoor", "Rogermoor@gmail.com", "9000510456", new Date(), "M", "Hyderabad"));
        USERS_TABLE.put(12, new User(12, "Robinhood", "Robinhood@gmail.com", "9247469543", new Date(), "M", "Hyderabad"));
        USERS_TABLE.put(13, new User(13, "Sean", "Sean@gmail.com", "9000510456", new Date(), "M", "Hyderabad"));
        USERS_TABLE.put(14, new User(14, "Gabriel", "Gabriel@gmail.com", "9247469543", new Date(), "M", "Hyderabad"));

        USERS_TABLE.put(userId, user);
        return userId;

    public void delete(User user)
    {
        if(user == null)
        {
            throw new RuntimeException("Unable to delete User. User object is null.");

    public Collection<User> getAllUsers()

    public User getUser(Integer userId)

        Collection<User> users = USERS_TABLE.values();
        Collection<User> searchResults = new ArrayList<User>();
        for (User user : users)
        {
            if(user.getUsername() != null && user.getUsername().toLowerCase().trim().startsWith(searchCriteria))
            {
                searchResults.add(user);
            }
        }
        return searchResults;

    public void update(User user)

                maxId = key;
            }
        }
        return maxId;
    }
}

Create UserManagedBean.java

package com.primefaces.sample;

import java.util.Collection;

import javax.faces.application.FacesMessage;
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
import javax.faces.context.FacesContext;

import org.primefaces.event.SelectEvent;
import org.primefaces.event.UnselectEvent;

@ManagedBean
@ApplicationScoped
public class UserManagedBean
{
    UserService userService = new UserService();
    
    private String username;
    private String password;
    private String searchUser;
    private Collection<User> searchUsersResults;
    private User selectedUser;
    
    public String getUsername()
    {
        return username;
    }
    public void setUsername(String username)
    {
        this.username = username;
    }
    public String getPassword()
    {
        return password;
    }
    public void setPassword(String password)
    {
        this.password = password;
    }
    
    public User getSelectedUser()
    {
        if(selectedUser == null){
            selectedUser = new User();
        }
        return selectedUser;
    }
    
    public void setSelectedUser(User selectedUser)
    {
        this.selectedUser = selectedUser;
    }
    public Collection<User> getSearchUsersResults()
    {
        return searchUsersResults;
    }
    public void setSearchUsersResults(Collection<User> searchUsersResults)
    {
        this.searchUsersResults = searchUsersResults;
    }
    public String getSearchUser()
    {
        return searchUser;
    }
    public void setSearchUser(String searchUser)
    {
        this.searchUser = searchUser;
    }
    
    public String login()
    {
        if("test".equalsIgnoreCase(getUsername()) && "test".equals(getPassword()))
        {
            return "home";
        }
        else
        {
            FacesContext context = FacesContext.getCurrentInstance();
            context.addMessage("username", new FacesMessage("Invalid UserName and Password"));
            return "login";
        }
    }
    
    public String searchUser()
    {
        String username = (this.searchUser == null)? "":this.searchUser.trim();        
        this.searchUsersResults = userService.searchUsers(username);
        System.out.println(searchUsersResults);
        return "home";
    }
    
    public String updateUser()
    {
        userService.update(this.selectedUser);
        return "home";
    }
    
    public void onUserSelect(SelectEvent event)
    {        
    }
    public void onUserUnselect(UnselectEvent event)
    {
    }
}

That all we need to do. You can run the application and see the rich user interface with blusky theme.

By default we don't get automcomplete for PrimeFaces tag in Eclipse. To enable AutoComplete,
Go to Window-->Preferences-->General-->ContentTypes
Select JSP and add .xhtml as file association.

You can download the sample as an Eclipse project Here

Thanks for the great tutorial. There are very few(almost nil) documents available online for Primefaces. You have taken a more serious example to explain Primefaces and it was really helpful.

I am exploring Primefaces. Would it be a good idea to invest on the ebook available on Primefaces site? Have you tried that? If you have other resources on this, can you share with me? my email is csshankaravadivel@gmail.com

Thanks again

Your code here looks like a nice place to start. Any chance of including a downloadable war file, so I can use it has a foundation to build upon?

Great tutorial man, thank you.
but instead of going with the *.jsf configuration you should now switch on to .xhtml part of the jsf. that the recommended one now i believe.

Hi Sasikumarm,
I recently gave a one more try to JSF2/EJB3 stack.
JSF2 improved over version 1.x but I feel still its hard to use because of its complex lifecycle.

I personally feel like if we want rich UI we can go for Vaadin or any Ajax Toolkit like YUI/jQueryUI.

Thanks,
Siva

It happens because there is no rowSelectListener in 3.0.M2; after deleting lines:

rowSelectListener="#{userManagedBean.onUserSelect}"
