PrimeFaces Push with Atmosphere

PrimeFaces Push is based on Atmosphere to establish WebSocket communication in an easy way. Bellow I will share the configuration to be able to do such kind of communication.
1- Adding the PrimeFaces and Atmosphere to the pom.xml for Maven dependency. Also, I added the dependency of the Apache Commons Lang3 to use the StringEscapeUtils while sending the notification message.
<dependency>
 <groupId>org.atmosphere</groupId>
 <artifactId>atmosphere-runtime</artifactId>
 <version>2.1.7</version>
</dependency>

<dependency>
 <groupId>org.apache.commons</groupId>
 <artifactId>commons-lang3</artifactId>
 <version>3.4</version>
</dependency>

<dependency>
 <groupId>org.primefaces</groupId>
 <artifactId>primefaces</artifactId>
 <version>5.0</version>
</dependency>
2- The web.xml configuration for the push servlet.
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <display-name>PrimePushNotify</display-name>
  <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
  </servlet-mapping>
  <servlet>
    <servlet-name>PrimePushServlet</servlet-name>
    <servlet-class>org.primefaces.push.PushServlet</servlet-class>
    <init-param>
      <param-name>org.atmosphere.cpr.broadcasterCacheClass</param-name>
      <param-value>org.atmosphere.cache.UUIDBroadcasterCache</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
    <async-supported>true</async-supported>
  </servlet>
  <servlet-mapping>
    <servlet-name>PrimePushServlet</servlet-name>
    <url-pattern>/primepush/*</url-pattern>
  </servlet-mapping>
</web-app>
3- Finally, let's try the notify example from the PrimeFaces showcase at http://www.primefaces.org/showcase/push/notify.xhtml.
First, notify.xhml
<html xmlns="http://www.w3.org/1999/xhtml"
 xmlns:h="http://java.sun.com/jsf/html"
 xmlns:f="http://java.sun.com/jsf/core"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:p="http://primefaces.org/ui">

<h:head>
 <title>Test</title>
</h:head>
<h:body>

 <p:growl widgetVar="growl" showDetail="true" />

 <h:form>
  <h:panelGrid columns="2">
   <p:outputLabel for="summary" value="Summary: " />
   <p:inputText id="summary" value="#{notifyView.summary}"
    required="true" />

   <p:outputLabel for="detail" value="Detail: " />
   <p:inputText id="detail" value="#{notifyView.detail}" required="true" />
  </h:panelGrid>

  <p:commandButton value="Send" actionListener="#{notifyView.send}" />
 </h:form>

 <p:socket onMessage="handleMessage" channel="/notify" />

 <script type="text/javascript">
        function handleMessage(facesmessage) {
            facesmessage.severity = 'info';
 
            PF('growl').show([facesmessage]);
        }
 </script>
</h:body>
</html>
Second, NotifyView.java
package com.ithinkisink.primepush.notify;

import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;

import org.apache.commons.lang3.StringEscapeUtils;
import org.primefaces.push.EventBus;
import org.primefaces.push.EventBusFactory;
 
@ManagedBean
@RequestScoped
public class NotifyView {
     
    private final static String CHANNEL = "/notify";
     
    private String summary;
     
    private String detail;
     
    public String getSummary() {
        return summary;
    }
    public void setSummary(String summary) {
        this.summary = summary;
    }
     
    public String getDetail() {
        return detail;
    }
    public void setDetail(String detail) {
        this.detail = detail;
    }
     
    public void send() {
        EventBus eventBus = EventBusFactory.getDefault().eventBus();
        eventBus.publish(CHANNEL, new FacesMessage(StringEscapeUtils.escapeHtml3(summary), StringEscapeUtils.escapeHtml3(detail)));
    }
}
Third, NotifyResource.java
package com.ithinkisink.primepush.notify;

import javax.faces.application.FacesMessage;
import org.primefaces.push.annotation.OnMessage;
import org.primefaces.push.annotation.PushEndpoint;
import org.primefaces.push.impl.JSONEncoder;

@PushEndpoint("/notify")
public class NotifyResource {

 @OnMessage(encoders = { JSONEncoder.class })
 public FacesMessage onMessage(FacesMessage message) {
  return message;
 }
}
I created that example as I have read some questions on stackoverflow.com that some guys wasn't able to do the configuration between PrimeFaces and Atmosphere.
You can find the complete example on my Github from this link:

  7. Our full Lace Front Wigs are all hand made with a lace cap. They are manufactured with thin lace sewn on top of the cap. Individual hairs are then sewn onto the thin lace. Each lace wig has lace all around the unit which will need to be cut prior to securing the wig to your head. You will need to cut along the hairline around your entire head. By doing so, you will be able to wear your hair anyway you like. You can even style ponytails, up-dos, etc. Once the Lace Wigs is successfully applied, it will appear that all the hair is growing directly from your head!

    Lace front wigs are hand-made with lace front cap & machine weft at back. Lace front wigs are manufactured with a thin lace that extends from ear to ear across the hairline. When you receive the wig, the lace will be quite long in the front. Cut and style according to your preference, as you will need to apply adhesive along the front of the wig. Once the wig is applied, you will still have Lace Wigs with a very natural appearance.

  8. 360Guide was born from passion for action sports, passion for writing and interest in the Internet. We have been snowboarding and surfing for a long time. We also enjoy wakeboarding and mountain biking and actually any sport that gives you adrenaline, soul, lifestyle, puts you outside and connects you with nature. Bmx And Mountain Biking
    From all the sports mentioned on this website, surfing is our biggest love. Since conditions over here are pretty bad, much more energy and inner fire must be given to the sport. Surfing freezing cold waters, shitty windswells, making our own surfboards and traveling all over the world… all this is behind us and we are looking forward to more of the same.

    Snowboarding is our second love… there is nothing more beautiful than powder covered mountains on a crisp bluebird sky morning. And all others are not far behind.

    The main goal of this website is to provide people with information on each of these sports. Info on equipment, choosing the right stuff, what matters and what doesn’t. A few words on the history of sport, where do we come from and where are we going. Tips on technique, how to guides for beginners. Basically all the things you wished you knew when you were just starting out and all the important info that will help you make an informed buy of your next surfboard, snowboard or whatever it is that you will be buying. The most important guides, tips and info can be found directly from the drop down menu at the top of the site. For the rest of the articles click on the desired sport in the same menu and a list of all articles related to that sport will be shown. Like at the end of this about us section everything linked to this site is displayed.

  10. Tongkat Ali ist eine Pflanze beheimatet in Südostasien. Sie gehört zur Gattung der Bittereschengewächse und Ihr botanischer Name lautet “Eurycoma longifolia”. Es gibt noch eine weitere Reihe länderspezifischer Namen
    wie z. B. “Pasak Bumi”, wie die Pflanze in Indonesien genannt wird oder “longjack”, die allgemeine Bezeichnung für Tongkat Ali Kaufen in den USA, Kanada und Australien.

    Das Ursprungsland von Tongkat Ali Kaufen ist Indonesien, daher findet man auch dort auch die größten Bestände. Weitere Vorkommen gibt es in Ländern wie Thailand, Malaysia, Vietnam und Laos.

    Die Einnahme von Tongkat Ali Kaufen empfiehlt sich insbesondere für Leistungssportler, die einen schnellen
    Muskelaufbau und Muskelzuwachs anstreben und nicht auf illegale und künstliche Substanzen zurückgreifen möchten um Ihren Testosteronspiegel zu erhöhen.

    Generell empfiehlt sich eine Einnahme von Tongkat Ali für alle Männer ab dem 30ten Lebensjahr, da in dieser Phase nachweislich die Produktion von körpereigenem Testosteron zurückgeht. Dies macht sich vor allem dadurch bemerkbar dass die körperliche Leistungsfähigkeit nachlässt, die Lust auf Sex spürbar abnimmt und dadurch allgemein das Selbstwertgefühl negativ beeinflusst wird.

    Mit der Einnahme von Tongkat Ali können Sie nachweislich Ihre Libido Steigern, Ihr Testosteron erhöhen und Ihre gewohnte Lebensenergie aus den jungen Jahren Ihres Lebens wieder herbeiführen. Hier können Sie übrigens weitere Informationen bekommen zum Thema ‘Libido steigern‘ ganz natürlich. Sollten Sie daran interessiert sein lohnt es sich auch unseren Artikel über Butea Superba zu lesen.

    Tongkat Ali wächst als Strauch und kann Höhen von bis zu 12 Metern erreichen. Typischerweise dauert es 10-15 Jahre bis solche Ausmaße erreicht werden. Der Strauch trägt anfangs grüne Blüten die sich im Laufe der Zeit, bis zur Reife, rot färben.

    Allerdings sind die Blüten im Hinblick auf die Wirkung der Pflanze weniger interessant. Der wertvolle Teil verbirgt sich unter der Erde.
    Im Laufe der Jahre wachsen die Wurzeln teilweise senkrecht und bis zu mehrere Meter tief in den Boden, was die Ernte zu einer schweren und mühsamen Arbeit werden lässt. Je älter die Wurzeln sind, desto höher ist auch die Anzahl der Wirkstoffe Butea Superba.
    Von daher gilt es einige Dinge zu beachten sollten Sie Tongkat Ali kaufen wollen.
