Hello ! I made a such thing for one client.
In facts and brievly, I made a persistence provider that was able to load propperties and create a delegated real persistence provider (hibernate for example). In my persistence.xml I refered to my own persistence provider. In this way I'm able to dynamically load some properties fixed when I deploy my app. The only bad thing is that each container can react differently. This work on TomEE and Webpshere 8.5 and Liberty (fully tested). good luck (theses point let me think that the JPA specification is missing some real life use cases). Just my 2 cents. 2015-07-17 18:28 GMT+02:00 Romain Manni-Bucau <rmannibu...@gmail.com>: > Well I'd just put the properties I want in conf/system.properties. > > Side note: if you want to do it by persistence unit you can as well > prefixing it by PERSISTENCEUNIT and the unit name as explained here > http://tomee.apache.org/properties-listing.html > > > > Romain Manni-Bucau > @rmannibucau <https://twitter.com/rmannibucau> | Blog > <http://rmannibucau.wordpress.com> | Github < > https://github.com/rmannibucau> | > LinkedIn <https://www.linkedin.com/in/rmannibucau> | Tomitriber > <http://www.tomitribe.com> > > 2015-07-17 7:52 GMT-07:00 Daniel Cunha <daniels...@gmail.com>: > > > If I get it.. > > > > You need to have something like DeltaSpike ProjectStage[1] where you > have a > > configuration for Development and another configuration for Production. > > > > So, maybe you can create a different Produce for each stage. > > > > Then with Alternative and Exclude annotations you can configure it. > > I'm not expert in this module of the DeltaSpike, but..
