Setting up primefaces push

[llper]

Dear All,
I'm trying to setup prime-push on my web application, but I'm unable to figure out the correct steps.
I'm using primefaces 3.0.M4-SNAPSHOT on tomcat 6.0.26, under eclipse..
I've modified my server.xml adding the new connector:

Code: Select all

<Connector connectionTimeout="20000" port="6080" protocol="org.apache.coyote.http11.Http11NioProtocol" redirectPort="8443"/>

and I've modified my web.xml adding params and servlet:

Code: Select all

<context-param>
        <param-name>primefaces.PUSH_SERVER_URL</param-name>
     <!-- <param-value>ws://www.primefaces.org:9090/prime-pushserver</param-value> -->
   <param-value>ws://localhost:6080</param-value>
    </context-param>

	<servlet>
		<servlet-name>Atmosphere Servlet</servlet-name>
		<servlet-class>org.atmosphere.cpr.AtmosphereServlet</servlet-class>
		<init-param>
			<param-name>org.atmosphere.useWebSocket</param-name>
			<param-value>true</param-value>
		</init-param>
		<init-param>
			<param-name>org.atmosphere.useNative</param-name>
			<param-value>true</param-value>
		</init-param>
		<init-param>
			<param-name>org.atmosphere.cpr.WebSocketProcessor</param-name>
			<param-value>org.atmosphere.cpr.HttpServletRequestWebSocketProcessor</param-value>
		</init-param>
		<init-param>
			<param-name>org.atmosphere.cpr.broadcastFilterClasses</param-name>
			<param-value>org.atmosphere.client.JavascriptClientFilter</param-value>
		</init-param>
		<load-on-startup>2</load-on-startup>
	</servlet>
	<servlet-mapping>
	  <servlet-name>Atmosphere Servlet</servlet-name>
	  <url-pattern>/prime-push/*</url-pattern>
	</servlet-mapping>

I've added all the required atmoshpere-0.X libraries to my build-path. In fact, when tomcat starts I can read:

Anyway, when I go to the web application, firefox (and safari) are unable to connect to the websocket. I get, as an example in FF:

• "NetworkError: 404 Not Found - http://localhost:6080/prime-push/chat"
  chat
  Firefox can't establish a connection to the server at ws://localhost:6080/prime-push/chat.

Does anybody know how to solve the problem? Could someone post a full tutorial how to use primepush with the current 3.0 release please?

Thanks for any help,

llper

The latest PF User guide has some basic instructions on how to set up Push:

"
Push Server

PrimeFaces Push uses a servlet as a dispatcher. This servlet should be in a different application than
the JSF application and at the moment can only be deployed on jetty server.

Code: Select all

<servlet>
  <servlet-name>Push Servlet</servlet-name>
  <servlet-class>org.primefaces.push.PushServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
  <init-param>
  <param-name>channels</param-name>
  <param-value>chat,counter</param-value>
  </init-param>
  </servlet>
  <servlet-mapping>
  <servlet-name>Push Servlet</servlet-name>
  <url-pattern>/prime-push/*</url-pattern>
  </servlet-mapping>

channels configuration defines the topic names that push server can publish to.

URL Configuration
The JSF application needs to define the push server url to send messages.

Code: Select all

 <context-param>
  <param-name>primefaces.PUSH_SERVER_URL</param-name>
  <param-value>ws://url_to_push_server</param-value>
  </context-param>

Hi there!
Just a small question on the setting up. The server has to be Jetty, right? It doesn't work on Glassfish, is that correct?

[drawinski]

Hi!

We are trying to get Primefaces push working by setting up a standalone Jetty (jetty-distribution-8.1.0.v20120127).
We are using Tomcat 6.0.35 as a servlet container for our application.
Our web.xml contains the following:
<context-param>
<param-name>primefaces.PUSH_SERVER_URL</param-name>
<param-value>ws://localhost:8787/pushserver</param-value>
</context-param>

When we navigate to a page which contains a <p:push> tag on our JSF page it subscribes to the specified channel.
But when we try to push some message from a backing bean via RequestContext to Jetty the primefaces PushServlet's onMessage() method is never called.
So basically, we can not send a push message to Jetty.

Can you please provide a correct web.xml that we can deploy to our Jetty push server?
Any other advices are also welcome!

Thanks,
Andrew

Dear Sirs,
I 'm struggling to get the Push Counter example to work.
Ref. Usergude 9. PrimeFaces Push: 9.1 Setup: See the copy from the manual in the lower part of the page:

The first part is refering to a pom.xml file in my application
Where shall I put this configuration when i dont have any pom.xml file?

Second part of the setup is a description of a dependency.
I guess these lines shall be in the WEB-INF/LIB/web.xml, but the <async-supported>true</async-supported> fails with: Invalid content was found starting with element 'async-supported'.

The libraryfiles atmosphere-runtime 2.4.2.jar and atmosphere-compat7-2.0.1.jar is in the projects library.

When I run the application and then press the Button for incrementing it appears a list of faultmessages which starts with the following faultmessage:

SEVERE: java.lang.NoClassDefFoundError: org/atmosphere/cpr/BroadcasterListener
at org.primefaces.push.EventBusFactory.<init>(EventBusFactory.java:26)
at org.primefaces.push.EventBusFactory.<clinit>(EventBusFactory.java:25)
at com.stnett.Push.GlobalCounterView.increment(GlobalCounterView.java:32)


Question No1: What shall i write where to get the examole Counter to work?
Question No2: Do I need to add some libraryfiles to the Tomcat-installation? I suppose NOT.

Difficult to find information about this in the documentation for Atmosphere and Tomcat as well.

Regards
-Gunnar

Using PF ver. 5.1
Tomcat ver. 7.0
RichFaces ver. 4.2
JSF2.0

Copy from the PF User Manual:

Atmosphere
Atmosphere is required to run PrimeFaces Push, in your pom.xml define the dependency as;
<dependency>
<groupId>org.atmosphere</groupId>
<artifactId>atmosphere-runtime</artifactId>
<version>2.3.RC6 or newer</version>
</dependency>


Push Servlet
Push Servlet is used as a gateway for clients.
<servlet>
<servlet-name>Push Servlet</servlet-name>
<servlet-class>org.primefaces.push.PushServlet</servlet-class>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>Push Servlet</servlet-name>
<url-pattern>/primepush/*</url-pattern>
</servlet-mapping>

[Miguel Cubells]

the <async-supported>true</async-supported> fails with: Invalid content was found starting with element 'async-supported'

Make sure you are using a servlet 3.0 compatible web.xml

Code: Select all

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<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">

Also, for Tomcat 7, you may need to use the atmosphere-runtime-native dependency, instead of the [atmosphere-runtime]

It works for me.
