You can also use the Atmosphere framework: https://atmosphere.dev.java.net/
If you use it with their jQuery plugin, you can easily get WebSocket support for clients that support it, with a fallback to Comet streaming for clients that don't. It can be a little bit of a pain to set up for the first time--the website is unfortunately lacking in a set of server-by-server instructions--but once it's set up it's usually pretty easy to use. -allen On Fri, Dec 10, 2010, 15:38, Daniil Sosonkin <[email protected]> wrote >This is pretty nifty. >Although I can't figure out yet how to make it work under tomcat. We're using tomcat so Jetty's solution below won't work for me. jWebSocket sounds like a perfect solution for me because it automatically falls back to Flash bridge in case WebSockets aren't available. But I don't want to run it on a whole different server/port since my whole web app is written on Stripes. >Once I figure out how to create an ActionBean I'll send it here or if someone else figures it out before me, please send it here too. >Daniil >On 12/9/2010 7:59 PM, samuel baudouin wrote: >Hi all, >Just my 2 cents : a quick search on google gave me this : http://jwebsocket.org/ >It appears to be a complete webSocket Framework (both java and js) that is independant from the container. >Combined with your solution, that could be a pretty and nice solution for supporting webSocket on any container/application server.... >I haven't tested it, but examples seems pretty straight forward. >Regards, >Sam >On Fri, Dec 10, 2010 at 3:21 AM, Sven Jacobs < [email protected] > wrote: >Hi, >I've looked at the source code of the WebSocketServlet of Jetty to find out how they initialize WebSockets and was able to "port" some code over to a Stripes Resolution.

I'm focusing on Jetty because it's one of the few servlet containers that already support WebSockets. However you have to create a servlet that extends from WebSocketServlet. That way I can't use the Stripes servlet and all the code in the WebSocketServlet runs "besides" and not within the Stripes framework. >So you are saying that I should implement the WebSockets protocol within Stripes? >Regards, >Sven >2010/12/9 Stone, Timothy < [email protected] > >Sven, >Jetty is a servlet container, e.g., Tomcat.
