I found that out late nite yesterday, thanks so much. Will look into all those.

But I also have a exception when I start embeeded jetty with (from java class) from jettyxml using DeploymentManager (have just a web.xml with a hello servlet  The websocket endpoint is only in the code, not referred anywhere in the code.

Could you please provide some pointers from where I should start looking, don’t find anything on the web?

Thanks so much for all your help.

JSR-356 does not support adding websocket endpoints via web.xml or via servlets.

 

Go read up on javax.websocket.server.ServerContainer (both the object and the ServletContext attribute)

 

You'll have a few choices:

 

* javax.websocket.server.ServerEndpoint Annotation scanning

* javax.servlet.ServletContextListener

* javax.websocket.server.ServerApplicationConfig

Hello all,

 

I can get the jsr356 working by manually adding the endpoints to the servletContainer as

wscontainer = WebSocketServerContainerInitializer.configureContext(context); WebSocketServerContainerInitializer.configureContext(context);

wscontainer.addEndpoint(MySocket.class);

 

However, I already have a jetty project that uses jetty.xml and web.xml for all other servlets, so I am trying to figure out how to add the end points via web.xml

Any help is greatly appreciated.

Regards

Anu
