[Wildfly 8.0.0.Final] Blocking request failed HttpServerExchange{ GET /primepush/message/qla/robert}: java.lang.NullPointerException

[ladrob]

Hi,

I've got the error from the title on page load. I'm using Primefaces 5.0.

My PushEndpoint resource file is:

    @PushEndpoint("/message/{domain}/{user}")
    public class SckMessageResource {

      @PathParam("domain")
      private String domain;

      @PathParam("user")
      private String user;

      @OnMessage(encoders = {JSONEncoder.class})
      public String onMessage(String message) {
          return message;
      }
    }

Full trace of error:

The error appears in Atmosphere 2.1.5 and above. Version 2.1.4 works fine.
Thanks for any hints.

[jfarcand]

@ladrob You means 2.1.5? Can you try 2.1.9?

[ladrob]

Oh, sorry, yes I mean 2.1.5. I've tried also 2.1.8 - the same problem. I'll try 2.1.9 and let you know. Thanks.

[jfarcand]

@ladrob OK lines of the exception aren't matching with the current version. Please try 2.1.9 and paste the exception again. Thanks

[ladrob]

Hmm.. 2.1.9 - no error, and doesn't work for me. Maybe I could try 2.2.1?

[jfarcand]

Yes give it a try.

[ladrob]

Now I have error:

15:54:29,014 ERROR [org.atmosphere.interceptor.JavaScriptProtocol] (default task-8) Invalid Atmosphere Version 2.2.0-javascript
15:54:29,014 WARN  [org.atmosphere.websocket.protocol.SimpleHttpProtocol] (default task-8) Status code higher or equal than 400. Unable to deliver the websocket messages to installed component. Status 501 Message OK

Still doesn't work. Why Invalid Atmosphere Version? In my pom.xml I have only atmosphere-runtime 2.2.1.

[jfarcand]

Update atmosphere-javascript to 2.2.4

[ladrob]

I cannot find in maven atmosphere-javascript. I've tried:
groupId: org.atmosphere
artifactId: atmosphere-javascript
version: 2.2.4

and

groupId: org.atmosphere.client
artifactId: javascript
version: 2.2.4

... missing artifact. :-(

[jfarcand]

http://search.maven.org/#artifactdetails%7Corg.atmosphere%7Cjavascript-project%7C2.2.4%7Cpom

[ladrob]

Sorry, I don't know what is going on. I've copy/paste dependency from link you provided (that I've tried on the beginning) to my pom and only this one dependency says: Missing artifact org.atmosphere:javascript-project:jar:2.2.4

I must find the problem and then I'll come back.

[flowersinthesand]

javascript-project is the parent project of atmosphere-javascript and atmosphere-jquery. You should use:

http://search.maven.org/#search%7Cga%7C1%7Corg.atmosphere.client

[ladrob]

I used jquery and javascript, but the same problem. My maven client download all but war files. I downloaded them manually and changed war extension to jar (because of compilation problem) and unfortunaltely I have simmilar error:

    17:29:23,105 ERROR [org.atmosphere.interceptor.JavaScriptProtocol] (default task-9) Invalid Atmosphere Version 2.2.0-javascript

Is everything alright with these artifacts? I haven't such problems with any yet.

[jfarcand]

NOT 2.2.0, 2.2.4

[ladrob]

Yes I know - I've installed 2.2.4 - I don't know why log says 2.2.0 still. It looks - it doesn't see new libraries.

[ladrob]

Too many actions and changes with atmosphere repo from my side. I'll remove all libraries from local mvn, restart my PC, clean everything and try again.

[ladrob]

I'll try with:

    <dependency>
        <groupId>org.atmosphere</groupId>
        <artifactId>atmosphere-runtime</artifactId>
        <version>2.2.1</version>
    </dependency>

    <dependency>
        <groupId>org.atmosphere</groupId>
        <artifactId>javascript-project</artifactId>
        <version>2.2.4</version>
        <type>pom</type>
    </dependency>

[ladrob]

I've still the same error: Invalid Atmosphere Version 2.2.0-javascript.
I'll back to 2.1.4. Sorry and thank you for your efforts.

[jfarcand]

You have javascript cached somewhere. Just tested on Wildfly and everything works for me. So try to come with a test case.

[ladrob]

How should pom.xml look like? I mean atmosphere libraries.

[jfarcand]

BTW for sure your error has been fixed

    @Override
    public void onClose(javax.websocket.Session session, javax.websocket.CloseReason closeCode) {
        logger.trace("{} closed {}", session, closeCode);
        if (request != null) {
            request.destroy();
            webSocketProcessor.close(webSocket, closeCode.getCloseCode().getCode());
        }
    }

The NPE was occuring because of request was null. This is fixed 2.1.5+ . You must update push.js if you want to use the latest atmosphere.js BTW by replace the atmosphere.js code inside that file. That's explain why 2.2.0 is still used.

[jfarcand]

Closing this issue as fixed.

[ladrob]

Ok, maybe this is primefaces push issue. PF doc suggests Atmosphere 2.1.3, so I'll back to 2.1.4 - as there were no errors for me. Thank you anyway and sorry for bothering you :-)
