a4j:push topic 'pushTest' is not configured

[healeyb]

I'm trying to get a4j:push working with CDI events on 4.1.0.Final. I have:

<a4j:push address="pushTest"

                ondataavailable="alert(event.rf.data)"/>

@Inject

@Push(topic = "pushTest")

private Event<String> pushEvent;

public void sendMessage() throws Exception {

        pushEvent.fire("let's see if this works 2");

}

web.xml

<context-param>

        <param-name>org.richfaces.push.jms.disable</param-name>

        <param-value>true</param-value>

</context-param>

pom.xml

<dependency>

            <groupId>org.atmosphere</groupId>

            <artifactId>atmosphere-runtime</artifactId>

</dependency>

When I load the page containing a4j:push, I get an alert saying topic 'pushTest' is not configured. When

I call the sendMessage() method the alert isn't opened by a4j:push. In the server log I see this output when

I deploy the application:

server log:

INFO: SESSION CREATED ID: 901939c9b5c1f6777c0ca6a844d2

INFO: Atmosphere is using async support: org.atmosphere.container.Servlet30CometSupportWithWebSocket running under container: "" with WebSocket enabled.

INFO: Installed AtmosphereHandler null mapped to context-path: /*

INFO: Installing Servlet null

INFO: Installing Filter PushHandlerFilter

INFO: Using broadcaster class: org.atmosphere.cpr.DefaultBroadcaster

INFO: Atmosphere Framework 0.8.0-RC1 started.

Is there any additional configuration required? I'm using glassfish 3.1.1 and have enabled comet.

Update: I've added a simple listener and changed the code to use HelloEvent, and the event is getting

fired successfully, so there must be something I'm missing on the a4j:push side of things.

@Stateless

public class HelloListener {

    public void listenToHello(@Observes HelloEvent helloEvent){

        SQLog.log("HelloEvent: " + helloEvent.getMessage());

    }

}

Update 2: when the page containing a4j:push loads I get the javascript alert box with the 'pushTest is not

configured' message referred to above, I ok this an then see this error in the javascript console (chrome browser):

1. GET https://localhost:8181/uk.co.sportquest_SportQuest_war_1.0.0/rfRes/org.richfaces.resource.PushResource.xhtml?__richfacesPushAsync=1&pushSessionId=a0c5e133-80a9-4310-ae6c-f37e3c4c8964 500 (Internal Server Error)

bump - Hi, I'm keen to know if I'm looking at a Glassfish/Weld problem here, or a more general issue.

Is anyone using a4j:push with 4.1.0.Final, if so with CDI events?

Regards,

Brendan.

Hi Brendan,

I faced the same problem, take a look at this :

Thanks Ibrahim, this is very helpful. I still have a problem because I'm running into this IllegalArgumentException:

Any ideas anyone? It's not exactly easy to use is it?

[iabughosh]

is it working now and throws this exception ?, are you calling pushEvent.fire from EJB context ?, pleasae post your bean and xhtml page.

also check this, i have some doubt about your filter (uk.co.sportquest.jsfbeans.helper.CacheFilterStatic.doFilter(CacheFilterStatic.java:138)) :

Hi Ibrahim, this is what I've got:

<a4j:log/>

<h:outputText id="uid" value="uid: #{leagueMgrFixturesView.userIdentifier}"/>

<a4j:push address="#{leagueMgrFixturesView.userIdentifier}@pushCdi"

          onerror="alert('error: ' + event.rf.data)"

          ondataavailable="alert('data: ' + event.rf.data)">

   <a4j:ajax event="dataavailable"/>

</a4j:push>

<a4j:commandButton value="push" action="#{leagueMgrFixturesView.sendMessage}"/>

and the java:

private static final String CDI_PUSH_TOPIC = "pushCdi";

    private String userIdentifier;

    @Inject

    @Push(topic = CDI_PUSH_TOPIC, subtopic = "#{leagueMgrFixturesView.userIdentifier}")

    private javax.enterprise.event.Event<String> pushEvent;

    @PostConstruct

    public void init() {

        if (userIdentifier == null) {

            userIdentifier = UUID.randomUUID().toString().replace("-", "");

        }

        TopicsContext topicsContext = TopicsContext.lookup();

        topicsContext.getOrCreateTopic(new TopicKey(CDI_PUSH_TOPIC, userIdentifier));

    }

    public void sendMessage() throws Exception {

        Log.log("sendMessage");

        pushEvent.fire("a test message");

        //pushEvent.fire(new HelloEvent("TEST"));

    }

Regards,

Brendan.

did u check your filter code (uk.co.sportquest.jsfbeans.helper.CacheFilterStatic.doFilter(CacheFilterStatic.java:138)) : ?

see this link for more information:

http://stackoverflow.com/questions/7607780/java-jsf-strange-error-warning-standardwrappervalve-pwc1406-servlet-service

[healeyb]

I did, the filter simply sets headers and calls chain.doFilter(req,res); - but I'll try without it just to be sure...

[healeyb]

I've just tried with the filter removed but still get the exception. I found two other posts on here from people with the same

problem, but no obvious solution. Hmmmm

Hi Brendan, as I said in similar topic [1],

the problem is the "pushTopic" is not propagated to the server.

It should not happen in your code, unless your <a4j:push address="" />.

It would be great if you could provide me maven app reproducing your issue so I can identify what's the problem.

After a fair bit of messing about I've got it working and here, as far as I can tell, is everything relevant to getting

this working. A few points to bear in mind:

1. I'm using a servlet v3 container (web.xml: web-app version="3.0") so don't need to declare the push servlet

    explicitly in web.xml, but you might need to.

2. I've seen some examples of a PushFilter in web.xml, this definitely was causing me problems and I only got

    it working after removing this.

3. I've seen it suggested to use this in the web.xml but I haven't needed to:

   <context-param>

        <param-name>org.richfaces.push.handlerMapping</param-name>

        <param-value>/__richfaces_push</param-value>

   </context-param>

4. There seems to be a problem with Atmosphere version later than (not including) 0.8.0-RC1

     that causes a NoClassDefFound error for WebSockets (something like that anyway). A big

     thanks to Vadim Si for figuring this out. The latest version 0.8.2 doesn't work.

5. The lines relating to topicsContext in the java file are needed - that's what causes the "topic

     'topic-name' is not configured error". These are missing from the showcase example, but are

    referenced in the component guide.

Brendan.
