Yes.. I looked at Background instance. It allows to have long tasks but it doesn't allow to spawn threads. Quartz fires off events in threads. So I guess quartz is not an option on app-engine. We can use appengine cron jobs to some extent but if you need to fire an event at exact minute, it would be tough.
It's tough to maintain 2 cloud providers for single product. Not sure how efficient it is to call appengine urls from EC2. May be move to EC2 completely may be better solution. We need object datastore for our product. Has anyone has experience with EC2 object datastore SimpleDB? Does it have same features and JPA/JDO interfaces like appengine. GAE datastore is pretty good but it doesn't give a "VM" ownership to the developer. The "Backends" in appengine still don't give any control of the server/instance to developer. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
