By the way, I'm trying to have a continuity of service when some external applications are down or send errors.
e.g. : An user fills a form on the web, the informations are sent by webservice to petals which is supposed to relay to a CRM. If the CRM is currently down or cannot process the datas right away, Petals would need to wait and resend until an "ok" answer is given. (With maybe a maximum numer of retry).
What should I use to do this ?
(Sorry if it would have been better to create a new thread for this question).
