play1.3.1 websocket address is 404 error

Question

我在tomcat8下使用play1.3.1的websocket，连接地址为404错误，play的websocket不支持Tomcat？谁能帮帮我？

Answer 1

May be it's a libraries issue, clean and then deploy your project it'll run fine..

Also check if this is the root of your error:

Tomcat has a JSR-356 (ie the websocket API) implementation since version 7.0.47. Which also provides the javax.websocket-api-1.0.jar library. You might need it at compile time but the server will provide it at runtime

Make sure javax.websocket-api-1.0.jar does not get deployed in your WAR, do a right click in your Eclipse server view, Clean... followed by Clean Tomcat work directory... then a Publish and try again.

Hopefully this will be helpful
