i’m using richfaces 4.2 and try to create a push system.

<a4j:push address="subtopic@topic">
 <a4j:ajax event="dataavailable" render="list" execute="@none" />
</a4j:push>


public void push() throws MessageException {
    TopicKey topicKey = new TopicKey("topic");
    TopicsContext topicsContext = TopicsContext.lookup();
    topicsContext.publish(topicKey, "empty message");
    System.out.println("push event");
}

but the rendered javascript on the client side seems to have a problem:

it try’s to get the following url

/rfRes/org.richfaces.resource.PushResource.html?__richfacesPushAsync=1&pushSessionId=1df3c2e1-37a2-4e96-993a-c881597e8cb2&_=1334760087852

but there is missing the “pushTopic” – get param wich results in:

does anybody know what i’m doing wrong?

EDIT:
i’m using tomcat7

i tried changing my bean to:

@Autowired
@Push(topic = "topic", subtopic = "subtopic")
// now Topic getting initialized with this.
private Event<String> pushEvent;

public void push() throws MessageException {
    pushEvent.fire("hello");
}

but then i get

    When I saw this with the same set up, it took me a good few hours to sort out. I eventuall resolved it by installing atmosphere-runtime.jar version 0.8.4 – it’s the only version compatible with Richfaces 4.2. The other steps I had to take were:

    Specify servlet version 3.0 in web.xml

    <web-app
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
     id="WebApp_ID"
     version="3.0"
 >

    Add the following jars to resolve various other dependencies in Atmosphere

    • atmosphere-compat-tomcat-0.8.0-RC1.jar
    • atmosphere-compat-0.4.1.jar
    • jetty-websocket-8.1.5.v20120716.jar
    • slf4j-api-1.6.6.jar
    • slf4j-simple-1.6.6.jar.

    EDIT: futher research and testing has demonstrated that it is not necessary to define a “Push Servlet” in web.xml for servlet version 3.0 under Tomcat 7.0.29, but for reference, for earlier versions, you do need this:

    <servlet>
    <servlet-name>Push Servlet</servlet-name>
    <servlet-class>org.richfaces.webapp.PushServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
</servlet>

    Also, guava-r08.jar and sac-1.3.jar are core “mandatory dependencies” for Richfaces – you need them for it to work even if you aren’t using Push.
