Comments

I've seen that the exception is catched but client does'nt receive the message. |
|
It's is easy to reproduce Thanks |
|
@jimmyjim The message will be cached. Please make sure you properly configured. |
|
For the configuration, i follow this documentation i've tried the 2 implementations of cache too reading this page https://github.com/Atmosphere/atmosphere/wiki/Understanding-BroadcasterCache I'm searching for 3 days ! |

Here The trace, i see warning telling atmosphereresource is not suspended. but in the managedservice, there is a SuspendTrackerInterceptor.class Infos: Déploiement de l'archive /home/jim/Applications/apache-tomcat-7.0.23/webapps/gwt20-managed-rpc.war de l'application web

@jimmyjim Please write sample that reproduce your issue and put in on Github. Thanks! |
|
Ok i've pushed it on to reproduce, deploy war in tomcat 7.0.57 (or older). i've switch protocol in server.xml to <Connector connectionTimeout="20000" port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol" redirectPort="8443"/>Thx |

Hi |
|
Yes i've read it. I've installed a broadcastercache but the messages aren't delivered. There is no traces, the method the listener onMessage doesn't receive response. I've commit the project (with params of configuration) to reproduce it on |
|
I have the same issue. Even if I turn on the cache, client receive nothing. |

Same problem here with Tomcat7, and I don't find a satisfying solution or a workaround to this. |
|
Anthony have you finally found the solution ? Thanks a lot. |
|
no, still the same problem |
|
@AnthonySantnet This is NOT an issue as I noted and that's expected. In 2.2.6 the log has been changed...but the application still works when such NPE happens. |
|
Ok, i've seen that you're catching the exception, but the application doesn't work even when setting a broadcastercache. As jimmyjim said, you can just deploy the "gwt20-managed-rpc" sample project in a tomcat container to see by yourself. |
|
Same problem here with
|
Is-it a bug in tomcat when the primary transport is set to long-polling?
Is it possible to disable native comet temporarily ?
