Eclipse project to build Jetty WebSocket server. Jetty servlet bridge implemented using Jetty 9 WebSocketServlet and WebSocketCreator. Includes a single page HTML/Javascript test harness.
Install Java.
Install Jetty (tested with jetty-distribution-9.2.13.v20150730).
In Eclipse add the following external jars to build path:
${jetty.home}/lib/servlet-api-3.1.jar
${jetty.home}/lib/websocket/websocket-servlet-9.2.13.v20150730.jar
${jetty.home}/lib/websocket/websocket-api-9.2.13.v20150730.jar
Export root.war from eclipse, copy to ${jetty.home}/webapps/root.war
Start Jetty:
cd ${jetty.home}
java -jar start.jar
Load WebSockets test harness http://localhost:8080/ . Connect using protocols clock, reverse or reflect. WebSockets servlet address is http://localhost:8080/ws.
Validate ServletUpgradeRequest in WebSocketDispatcher e.g. check for mandatory HTTP headers or known user with req.getUserPrincipal().getName(). Returning null will close connection before WebSocket is established.
Add WebSocket* using WebSocketReflect class to service specific protocols.
