问题 I am just starting with the Oracle Java EE 7 tutorial. While I have already gained some practice with an existing Apache Tomcat Environment I wanted to get in touch with the complete tutorial to have a clear learning path and trail. So I am currently using a Mac with OS X Mavericks. I have already installed an Oracle JDK 1.7 which is working pretty smooth. Developing is also nice so no problems with that.

问题 I'm using Websocket-API based on JavaEE 7, in my application. I'm required to access the values set in cookies inside my websocket endpoint [Annotated one : @ServerEndpoint ("/websocket") ] . How would I do that? @onOpen() method is there, which will be called automatically when a connection to this websocket endpoint is established. I want to access cookies values in there, inside this method. I know how to do that in a servlet or JSP, but I'm new to Websockets. Please help me doing this.
