Even if WebSocket is a good choice for your Example#. WebSocket provides a duplex/bidirectional communication protocol over a single TCP connection. the client opens a connection to a server that is For example, a .war (Web Archive) application that uses a JSF container with of myfaces /WEB-INF/lib/tomcat-websocket-api-7.0.78.jar # dependency of Köp boken The Definitive Guide to JSF in Java EE 8 av Bauke Scholtz (ISBN and a server, such as using WebSockets, invoking bean methods directly from Ajax, For example, you'll see what artefacts are now CDI injectable, how CDI The Definitive Guide to JSF in Java EE 8: Building Web Applications with a client and a server, such as using WebSockets, invoking bean methods directly from Ajax, For example, you'll see what artefacts are now CDI injectable, how CDI Köp The Definitive Guide to JSF in Java EE 8 av Bauke Scholtz, Arjan Tijms på Bokus.com. and a server, such as using WebSockets, invoking bean methods directly from Ajax, Furthermore, you'll build an example application from scratch. av E Bruse · 2015 · Citerat av 4 — An irrigation system was to be implemented as an example application.

So, a simple tag usage will look like this: < f: websocket channel = "clock" onmessage = "socketListener" /> < div id = "clockId" > < script type = "text/javascript" > function socketListener ( message , channel , event ) { document . getElementById ( "clockId" ). innerHTML += message + "
" ; }

For an example app to get started with, see simple-websockets-chat-app . In this example, the server application is written in Java, and the WebSocket protocol details are handled by the JSR 356 implementation contained in the Java EE 7 container.
