java - @ServerEndpoint( "/websocket") 404 -

i'm trying implement http://www.byteslounge.com/tutorials/java-ee-html5-websocket-example

however can't map /websocket on class

@serverendpoint( "/websocket") public class websocketcontroller {   } 

i can method map using

@responsestatus(value = httpstatus.ok) @requestmapping(value = "/websocket") public websocketcontroller<string> logerror() { } 

but can't use same @requestmapping on class, , @serverendpoint isn't having effect.

error is

 30217 [qtp351496750-25] warn org.springframework.web.servlet.pagenotfound - no mapping found http request uri [/websocket] in dispatcherservlet name 'spring mvc dispatcher servlet' 

can help!?
