[jboss-jira] [JBoss JIRA] (WFCORE-336) Ability for Deployment Overlays to overlay System Properties

[Brian Stansberry (JIRA)]

    [ https://issues.jboss.org/browse/WFCORE-336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13170505#comment-13170505 ] 

Brian Stansberry commented on WFCORE-336:
-----------------------------------------

If WildFly full's ee subsystem is configured, WildFly supports using deployment specific properties in expression resolution. The properties are read from file META-INF/jboss.properties, if present. So using file overlays for that file should provide something pretty close to the requested functionality.

> 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.
