Info: WebSocket connection is closed, code: 1006 when trying to run web memory samples

Question

I embedded tomcat 8.0.20 and used it on my server. I create a webcocket tomcat example, and when I try to run it on my server for all 4 examples (Echo, chat, etc.), I get

Information: WebSocket connection is closed, Code: 1006

In the console, it prints something like (URL is correct for sample)

Connection to WebSocket for 'ws: // localhost: 9763 / examples / websocket / echoProgrammatic' failed: WebSocket handshake error: Unexpected response code: 302

When I deploy this to tomcat, it shows error 404 instead of 302.

Can someone tell me what could be causing this?

In pom, my dependency is as follows

 <dependency>
     <groupId>javax.websocket</groupId>
     <artifactId>javax.websocket-api</artifactId>
     <version>1.0</version>
     <scope>provided</scope>
 </dependency>
