Sorry this might sound naive to JMS gurus, but still.
I have a requirement where a Spring based application is not able to connect synchronously to a SAP back-end (via their web-service interface) because the response from SAP is way too slow. We are thinking of a solution where the updates from GUI would be saved by the Spring middle-ware in a local database, simultaneously sending a message to a JMS queue. We want that after (say) every few hours (or may be nightly) a batch job runs to consume the message from the JMS queue, and based on the message contents, queries on the local database and sends the result to the SAP web-service.
Is this approach correct? Would I need a batch to trigger the JMS message consumption (because I don't want to consume the message immediately but in a deferred manner and at a pre-decided time)? Is there any way in Spring to implement this gracefully (like Camel)? Appreciate your help.
