Deployment of 'events-push' app into Tomcat

[thomasbee]

Stephane, all,

I sort of have the events-push plugin running the way I need it, however I still have 2 issues

(1) pushing events doesn't run when I start the app from within Intellij (not errors reported), but it runs fine when starting from the command line

(2) When I deploy into Tomcat 7 with NIO connector enabled, i.e.

    <Connector port="7777" protocol="org.apache.coyote.http11.Http11NioProtocol"
               connectionTimeout="20000"
               redirectPort="8443" />

I get the following error when pushing an event (note that this is running without errors from the command line)

java.lang.IllegalAccessException: Class org.grails.plugin.platform.events.registry.DefaultEventsRegistry$ListenerHandler can not access a member of class org.grails.plugin.platform.events.push.EventsPushHandler$BroadcastEventWrapper with modifiers "public"

Could it be that the push URL is somehow wrong? It is assembled in

$(function(){
      window.grailsEvents = new grails.Events('${createLink(uri: '')}', null, {transport:'long-polling'});

      grailsEvents.on("myEvent", function(data){
          alert('hello')
      });
});

Thanks

I can confirm the above error on

- Grails 2.1.0
- Tomcat 7.0.28
- Linux and MacOS

----
Changes to the demo as follows

- empty resources.groovy

commented out the following lines in BuildConfig.groovy

//  runtime 'org.springframework.integration:spring-integration-amqp:2.1.1.RELEASE'
//  runtime ":cloud-foundry:1.2.2"
//  runtime ":rabbitmq:1.0.0.RC1"
//  runtime ":events-si:1.0.M2-SNAPSHOT"
 

I have enabled the NIO connector in Tomcat.

Thanks

It seems that the demo on cloudfoundry also does not push anything ...

http://grailstodos.cloudfoundry.com/todos

or am I missing something?

[smaldini]

No I didn't miss those bugs I plan to redeploy. Cloudfoundry is not the best option to deploy a tomcat 7 pushed app with websockets (not supported). The bug is quite strange, but I think its fixed on trunk (M2 , not released yet).

Thank you for your feedback anyway :)

BTW be sure to use grails.tomcat.nio=true in your BuildConfig or you will have to use that in your JS:

new grails.Event(url,null, {transport:'long-polling'})

Hi Stephane,

Thanks for the fast reply. I do have

grails.tomcat.nio=true

BuildConfig.groovy

It is a minor issue that push doesn't work when running inside IntelliJ, running inside STS it works :-)

My main concern is that when deploying to Tomcat it doesn't work. (see stack trace in original post). Were you referring to this as a bug or only to Cloudfoundry?

in other words, I cannot get it deployed into Tomcat 7 for now.

Thanks a lot

In Tomcat, the above exception happens for both


long-polling and websocket

As transport. I have the demo of the alternative  atmosphere plugin running fine,

.t

[thomasbee]

Played around with Tomcat 7.0.27/28/29 all behave slightly differently. When deploying an app with the atmosphere plugin into Tomcat, the only working config is 7.0.27, all other produce errors on the identical WAR.  I am still stuck with the ToDo Example

https://github.com/smaldini/grailsTodos 

after removing

- Spring Framework Dependency
- events-si Plugin
- rabbitmq
- cloudfoundry

the sample is working fine with "rails run-app" but continues producing the above error when deployed into Tomcat.

Any ideas would be truly appreciated.

.t

[twhtanghk]

The same exception is thrown when run an application with "afterInsert" event registered by "grails run-war", but it runs fine by "grails run-app". It seems that the exception is thrown from plugin "platform-core" instead of "event-push".

[smaldini]

Will test that this eve and come back to you.

any news ... Stephane?

Ok, I am falling back to the grails atmosphere  rather than event-push plugin with "streaming" transport for the time being. Cannot get the other plugin to work when deploying on Tomcat.

.t

[smaldini]

Sorry I didn't get any chances to debug that this week.. I've worked on some patch locally but didn't release them yet.
