James,
My question is in relation with the spring event component.
Client : java web application server designed as an AJAX application and
using cometd/bayeux technology to provide push mechanism from web server to
the browser client. From the web site, the client can call a service "track
a parcel" who will register the client HTTP request + sessionId + parcel to
be followed) into a tracker event service (=subscription).
Server : A camel bus runs in // and subscribe to the events (of the tracker
event service) for which the status of the parcel must be provided. For each
event (1 event corresponds to one client HTTP request and one parcel id), it
will call different process on a regular basis (by example triggered by
quartz) :
from("quartz:every 10 minutes")
.to("event://track") <-- fetch events for which we have to check the status
.to("bean:checkStatus")
If a parcel has been delivered and its status is equal to "deliver", then
camel must raise an event to inform back the event listener of the web
application server. The client having a subscription to this event will be
notified back '(= push) in its browser (through AJAX & JSON) that its parcel
has been delivered.
KR,
Charles
