OK you are using a 1.6.0-SNAPSHOT so they must have fixed the issue because with today's SNAPSHOT, I can't reproduce it

Hmmm, i just download latest TomEE+ 1.6.0 snapshot; i don't use web profile. did you download-and-test tomee+ or tomee 'web profile' ?

I still get the same WARNING. at gist URL below, you will see entire tomee+ (catalina) log after starting tomee+.

I have the same behavior on TomEE 1.6

[jfarcand]

@karlkilden Which Atmosphere version are you using? Try 2.2.0-RC2

[jfarcand]

In any case, this is just a warning, so you application will still works.

jfarcand hi and thank you for a quick response. My compliments on a great project too, really looking forward to using it in my upcoming project. However for now It is not working for me, this is the full log using latest versions of Atmosphere-CDI, Tomcat7-compat and the runtime.

I got hello world working some time ago using a plain tomcat but other then that I am a novice so I apologize if I have some stupid error...

I commited and pushed to my test project. If you would like to try it yourself it can be browsed and cloned from here: https://github.com/karlkilden/ref The readme explains how to run it.

I added PrimePush for the function "Group Setup". In the gui you click Admin -> Group Management -> Setup Group and create a group (just random name will suffice).

the source code is groupSetup.xhtml (the socket is in template.xhtml) The bean is GroupSetupBean.java

The EndPoint is: NotifyResource.java

I am on twitter, google+ and your irc channel if you want to talk to me live...

Also, scanning does not make sense. I would rather demand from TomEE that they scan and give Atmosphere the result. I feel combined scanning for all frameworks is required to maintain lean boot time.

My preferred method of feeding you my annotated instances would be to have a simple config class like:

public interface AtmosphereAnnotatedTypeControl {
public Collection<Class<?>> atmosphereAnnotatedTypes();
}

[jfarcand]

@karlkilden Contribution welcomed :-) Atmosphere do get the list of annotaed classes from the Servlet 3.0 mechanism (looking inside the AnnotationDetector class in Atmosphere).

I won't have time to debug this this week for sure. But I know it works, so most probably an application error. Try with the atmosphere-samples (here and let me know if that one fail. You can also go on EE mailing list and ask them.

[karlkilden]

Ok but note that this is when using Atmosphere with PrimePush and I am already using the samples from Primefaces...

2014:06:09 09:41:46 ERROR org.primefaces.push.PushServlet: No Annotated class using @PushEndpoint found. Push will not work.

I am pretty sure I have a class annotated with @PushEndpoint ;)

[jfarcand]

OK please open another issue. In the issue, turn the Atmosphere log to TRACE as well as org.primefaces.push.* and attach it (or gist it) to the new issue.

[karlkilden]

Thanks and done:

#1624

Maybe Atmosphere should use The Reflection API tools from apache:
The easy mode:
List lista = new ArrayList<>();
Reflections reflections = new Reflections("pakage");
Set<Class<?>> annotated = reflections.getTypesAnnotatedWith(anotation.class);

   <dependency>
        <groupId>org.reflections</groupId>
        <artifactId>reflections</artifactId>
        <version>0.9.10</version>
    </dependency>

Or maybe alow custom AnnotationProcessor...

[jfarcand]

@salviof Atmosphere supports that. Check the documentation (via web.xml)
