I had a sample that worked for one case.. but it was long time ago and it
was only for testing.. now that I have something working and ready to
migrate, it's more easy.
I don't mind using Grizzly 2.0. Will need to try it for once :)
Would be great it if we can have that soon. JGroups can't do that (because
they are adding headers to the messages), Mina don't plan that until 3.0.
Still waiting for Netty response.
For me it's something that look basic, just don't know why it's not
implemented, maybe people using more TCP..
Do you thing you can provide a draft soon ?
