Ability for Deployment Overlays to overlay System Properties ------------------------------------------------------------ Key: WFCORE-336 URL: https://issues.jboss.org/browse/WFCORE-336 Project: WildFly Core Issue Type: Feature Request Components: Domain Management Reporter: Joshua Henn Currently Deployment Overlays allow only the replacing whole resource files. It would be nice to also be able to overlay System Properties that take precedent over globally defined properties. ie. {code:xml} <deployment-overlays> <deployment-overlay name="myOverlay"> <system-properties> <property name="datasource" value="java:jboss/datasources/controller"/> </system-properties> <deployment name="controller.war"/> </deployment-overlay> </deployment-overlays> {code} Usecase: Have two deployments active of the same application, run-time configured by descriptor replacements via System Properties.
