webSocket with Java Error during WebSocket handshake: 404

Question

I am using webSocket with java 1.6 and HTML.

This is my reference example

https://www.byteslounge.com/tutorials/java-ee-html5-websocket-example

When i go to http://localhost:8012/sessionLink/byteslounge/page.html

the error 404 is shown as below

WebSocket connection to 'ws://localhost:8012/sessionLink/websocket' failed: Error during WebSocket handshake: Unexpected response code: 404

Here is my code

Server Side

@ServerEndpoint("/websocket") 
public class WebSocketTest {

...

}

HTML

<script type="text/javascript">
    var webSocket = 
    new WebSocket('ws://localhost:8012/sessionLink/websocket');   
    ...
 </script>

Am i setting the WebSocket wrongly ?

localhost:Port/path setted in tomcat/@ServerEndpoint

Answer 1

尝试使用更高的jdk版本，java 1.6或更低版本不支持websocket。
