Hi all – I’m a newbie with Vaadin and am trying to setup a very simple “Hello World” project to run under IntelliJ v14 and Google App Engine. I am getting some exceptions related to the Atmosphere framework/Push-Server functionality:
org.atmosphere.cpr.AtmosphereFramework configureBroadcaster: Unable to configure Broadcaster/Factory/Cache org.atmosphere.cpr.DefaultBroadcasterFactory$BroadcasterCreationException: java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "modifyThreadGroup")
Browsing the forum, this seems to be related to Push Server not being supported for GAE with the recommendation to remove it. I am using IntelliJ v14 and the only places where I found I could remove push-server stuff were in
Vaadin_Server.xml
where I removed the following config lines
<root url="jar://$PROJECT_DIR$/../Libraries/vaadin-all-7.4.0/vaadin-push-7.4.0.jar!/" />
<root url="jar://$PROJECT_DIR$/../Libraries/vaadin-all-7.4.0/lib/atmosphere-runtime-2.2.4.vaadin2.jar!/" />
Still, I keep getting the previous exception and a bunch of other Atmosphere related questions. Question is how to properly remove/disable Vaadin Push so that it works with GAE/IntelliJ
Much appreciated!
