• Notifications with dojox.socket, Servlet 3.0 Async, and EJB 3.1 TImers (Web 2.0 and Mobile Development Community)
  The Web 2.0 and Mobile Feature Pack for WebSphere ships the latest version of dojo. One of the new technologies in dojo is dojox.socket. Dojo 1.6 introduces a new API for Comet-style real-time communication based on the WebSocket API. WebSocket provides a bi-directional connection to servers that is ideal for pushing messages from a server to a client in real-time. Dojo’s new dojox.socket module provides access to this API with automated fallback to HTTP-based long-polling for browsers (or servers) that do not support the new WebSocket API. This allows you start using this API with Dojo now.
