Architecture
This graphic is described in the surrounding text.
Client:
integrate dojo cometd API in a hidden widget (WebMsg)
subscribe topic and receive inbound message by using a UDTT widget and ECA
publish message to server and/or browser by using a UDTT widget and ECA
Server:
provide a UDTT service (WebMsgService) to publish message in operation/flow
publish message to browser client instantly (without notable delay) by using a UDTT operation/service
support both WAS and Weblogic
use UDTT program model (context, operation and service) only
(In another words, the implementation on WAS and Weblogic is transparent to the end programmer.)
