问题 I have socket server (java desktop app) that is waiting for connection from java webapp (socket client). The communication looks ok, I see message from the server on the client side, but when I send the message, I don't receive anything on my server side. What can be the problem?

问题 I have a standard websocket endpoint based on Tyrus implementation which times to times triggers the java.lang.IllegalStateException: Cannot set WriteListener for non-async or non-upgrade request .

EnityManager Injection via HK2 in WebSockets

由 风格不统一 提交于 2019-12-13 03:12:53
问题 I have written 2 WebSocket ServerEndpoints that inject Services that themselves interact with the Database using injected instances of the JPA EntityManager. The application is a web application deployed on a Tomcat Server, using Jersey as JAX-RS implementation and Hibernate as JPA Provider. Sometimes it happens that the EntityManager is closed when trying to the DB inside the Endpoints. Also I fear I might have produced code that triggers a Memory Leak. This is the custom ServerEndpoint

Apache Camel Content Based Routing on Websocket Connections

由 ∥☆過路亽．° 提交于 2019-12-11 10:16:05
问题 I have a hypothetical scenario: let’s pretend I have an Apache Camel websocket server and I’m allowing many websocket connections. Each client connection will need to be associated with a ClientID. The ClientID is obtained by a new connection via an InitConnection json message where a ClientID is a member of the message. The question is: is it possible to have camel associate a websocket instance with a ClientID in order to perform content based routing? 回答1: yes, It is possible. you can

What draft does java-websocket's WebSocketServer use?

由 限于喜欢 提交于 2019-12-11 02:53:11
问题 I can't figure out from the WebSocketServer.java source which draft it uses. The WebSocketClient.java can use RFC 6455, Hybi 17, Hybi 10, Hixie 76, and Hixie 75 yet defaults to RFC 6455. What draft does java-websocket's WebSocketServer use? 回答1: It supports whatever drafts you want it to support. The constructor supports passing in a list of Drafts that you want the server to handle. https://github.com/TooTallNate/Java-WebSocket/blob/master/src/main/java/org/java_websocket/server
