I'm trying to use Atmosphere Framework based Primefaces Push (with WebSockets) on WebSphere Portal 7 (running on WAS 7, which uses Java EE 5 -> Servlet 2.5). I just read that WAS 7 doesn't support WebSockets (doesn't have a WebSockets API), so I'm looking for some kind of workaround.
Is there anyone who had a similar problem and found a solution?
Websockets need at least java ee 7 container and servlet 3.1 API level. If you can switch to longpooling in your component you have a chance, otherwise not. It's not a matter of hack, your server needs to support protocol upgrade.
