[@ruixue6955]

10:16 *Events* 10:54 CDI enables you to create an observer pattern without actually implementing the classic oo observer pattern 11:02 you are able to inject an *event handler* that's tied to a type and then able to produce those events 11:13 *caution: event handling is not asynchronous* 11:56 code demo 12:38 web socket code demo 15:47 demo 15:57 16:05 post 17:23 question: is it a kinda long polling? 17:25 answer: no, because of the *web socket* 17:36 web socket gives u full duplex communication 18:05 what does *web socket* do: 19:29 magic glue - 19:51 the JEE "magic glue" is *CDI* 20:54 *interceptors* 22:42 Qualifiers 23:57 How does it work 27:20 conclusion
