Lack of asynchronous support in the Servlet 2.5 specification has caused server vendors to devise workarounds by weaving proprietary classes and interfaces that promote scalable Comet programming into the Servlet 2.5 API.As Servlet 3 support async processing, I think there is no need to Comet programming (CometEvent, CometFilter, CometFilterChain, CometProcessor, CometEventImpl, CometConnectionManagerValve classes are no longer needed). I think others features like annotations will not be useful > 2. The filter requires a ServletContext at initialisation. How might you > handle this for a filter defined at the Engine/Host level? My idea to handle this is as follow - tracks other component that can be defined at Context and Host, for example HttpServlet (<servlet> </servlet> tag).- read HttpServlet implantation and specification, then try to make implementation to FilterClass implement Filter interface, same as HttpServlet, so Filter can be defined at host level. Then try to make necessary modification on Filter to wide it at Engine level. > 3. Authentication will require access to Tomcat internals. Is a filter the > right solution for these valves?
