Hi,
I’m trying to deploy a very simple Vaadin push application.
It works fine with Tomcat and web sockets.
When I deploy the same application with weblogic 12c (12.1.2) I get a message in the debug console saying that websockets is not supported :
Push connection using primary method (websocket) failed. Trying with long-polling
I also get this message in the server console:
SEVERE:
java.lang.NullPointerException

And after that 9 times out of 10 the application just hangs and I get this kind of messages each time I try to do an action:
