Hello CXF Experts, Sergey, Aki, I have some issues to implement a simple test using WebSocket with CXF 3.1.7, in a Tomcat 8 Servlet container.
To make troubleshooting easier, I shared my demo project (based on the official CXF samples written by Aki): https://github.com/AnthonyMullerPlayground/cxf31_websocket The webapp context is "cxf31_websocket" and it contains a simple RESTful service running under "/services/users" path. The project also contains a basic index.html webpage to test the websocket. CXF is bootstrapped using: org.apache.cxf.transport.servlet.CXFServlet Spring is used to and configured this way with a "beans.xml" file: <jaxrs:server id="websocketService" address="/" transportId="http://cxf.apache.org/transports/websocket"; /> <context:component-scan base-package="com.sap.businessobjects.amuller"/> When I check the websocket using Chrome, the following error is displayed in the Network panel of the developer tools: Request headers: GET ws://localhost:8080/cxf31_websocket/services HTTP/1.1 Host: localhost:8080 Connection: Upgrade Pragma: no-cache Cache-Control: no-cache Upgrade: websocket Origin: http://localhost:8080 Sec-WebSocket-Version: 13 User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.116 Safari/537.36 Accept-Encoding: gzip, deflate, sdch Accept-Language: en-US,en;q=0.8,fr;q=0.6 Sec-WebSocket-Key: Uc/E4OEE/BnKx/EvHUgLtQ== Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits Response headers: HTTP/1.1 501 Not Implemented Server: Apache-Coyote/1.1 X-Atmosphere-first-request: true X-Atmosphere-tracking-id: aeeb9f45-62e8-45b4-9d37-4657988e20ec X-Atmosphere-error: Websocket protocol not supported Transfer-Encoding: chunked Date: Wed, 28 Sep 2016 15:21:58 GMT Connection: close No error is displayed in the Eclipse console... I'm stuck because I didn't really get the magic behind the scene. It seems that the transportId attribute is enabling the full WebSocket logic? (transportId="http://cxf.apache.org/transports/websocket";) Thanks for your help and explanations. Best regards, Anthony MÜLLER
