Polling Java app hosted on SCP

former_member186710 — Tue, 27 Jun 2017 15:18:40 GMT

Hi,

we need to deploy java app on SAP Cloud Platform (SCP), which:

runs constantly 24/7
Queries HANA database in set time intervals (polling)
Send emails to recipients based on the result of the DB query
No front end UI

can someone advise how this can be done please? SCP supports deployment of Java EE web apps. But this is not a web app nor servlet as it doesn't have any front end UI.Any help much appreciated!Thanks!

Hi Peter,

Do you have a SCP production account with Java compute unit and a HANA DB?

Thanks,

Jin

Hi Christian,

yes, which container to choose? EJB sheduler? Is there any blog or tutorial for this sort of thing anywhere as I could not find anything relevant?

Thanks
Peter
