jsr356

Using the Tyrus reference implementation of Java's "JSR 356 - Java API for WebSocket", I cannot find a way to access the HTTP connection that was used for the Websocket upgrades. Thus, I cannot access the HTTP headers that the browser sent. Is there a way to read the HTTP UserAgent header? Casting a "Session" object to "TyrusSession" or similar would be acceptable, I have to do it to get the Remote Address anyway. Sending the UserAgent again as a message inside the Websocket connection would be my fallback solution. WARNING: ServerEndpointConfig is shared among all endpoint instances and

I'm new to Spring (and asking questions on stackoverflow). I'd like to start an embedded (Tomcat) server via Spring Boot and register a JSR-356 WebSocket endpoint to it. This is the main method: @ComponentScan @EnableAutoConfiguration public class Server { public static void main(String[] args) { SpringApplication.run(Server.class, args); } } This is how the configuration looks: @Configuration public class EndpointConfig { @Bean public EchoEndpoint echoEndpoint() { return new EchoEndpoint(); } @Bean public ServerEndpointExporter endpointExporter() { return new ServerEndpointExporter(); } } The

I am trying to implement some application based on websockets which will communicate with JS clients quite intensively. The code to send the message is quite primitive: synchronized (session) { if (session.isOpen()) { session.getBasicRemote().sendText(message); } } For rare sending it works just fine, but when few threads are trying to send some messages by the same session (socket), next exception is thrown (please note that it is not multithreading issue because code block is synchronized by session): java.lang.IllegalStateException: The remote endpoint was in state [TEXT_FULL_WRITING] which
