PrimePush in Jboss AS 7

It toke me a while to make PrimePush work in JBoss AS 7.
In this post I will just paste the codes of a simple hello world like program that uses PrimePush libraries to submit an String to a web socket.

The requirement for this exercise, is that you know to create a new JSF project with maven and deploy it into the JBoss 7 AS application server. All the steps to do that can be found in one of my previous post:
http://javing.blogspot.ie/2013/01/how-to-create-new-jsf-21-project-and.html

Once you have your project ready, lets make the following changes in the configuration files:

Now that everything should be configured, lets write a very simple JSF 2 program to show a primepush.

MyCommentBean.java

1:  /**  
2:   * The JSF Backing bean that will push the messages into the socket.  
3:   */  
4:  package my.first.push.project;  
5:  import javax.faces.bean.ManagedBean;  
6:  import javax.faces.bean.RequestScoped;  
7:  import org.primefaces.push.PushContextFactory;  
8:  @ManagedBean(name = "myCommentBean")  
9:  @RequestScoped  
10:  public class MyCommentBean {  
11:    public static final String BROADCAST_CHANNEL = "/comment";  
12:    private String comment;  
13:    public String getComment() {return comment;}  
14:    public void setComment(String comment) {this.comment = comment;}  
15:    public void publish() {  
16:     PushContextFactory.getDefault().getPushContext().push(BROADCAST_CHANNEL, this.comment);  
17:     this.comment = "";  
18:    }  
19:  }  

So now that we have the application, compile and deploy it in JBoss.
Run it on your browser by just accessing the URL:
http://localhost:8080/pushcomment/

Open a few browsers and see how all the clients listening to the socket will get the updates:
