I'll add a oneWay boolean attribute to AbstractPacket. In the packet handler, before leaving the handle() method, I check if there is a response to send or if the oneWay boolean is set to false on the request. If the boolean is set to false, I'll send a NullPacket() to "unblock" the client side. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4124042#...
