[jboss-jira] [JBoss JIRA] (WFLY-8868) per application Expressions

[Juergen Weber (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-8868?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13415585#comment-13415585 ] 

Juergen Weber commented on WFLY-8868:
-------------------------------------

META-INF/jboss.properties is an interesting mechanism, but it still requires individual patching of an ear or deployment overlays (which do only work for CLI). 

Concerning ease of deployment it makes no difference if I write the queue name into ear/ejb/ejb-jar.xml/<activation-config-property-value>
or into ear/META-INF/jboss.properties, for both I have to patch the application on deployment.

An alternative to my suggested <application-properties>
would be a jboss-application.properties in the server config dir with entries like

myMDB_DEV_QUEUE_1.ear.queuename=DEV_QUEUE_1

which should resolve via 

<activation-config-property-value>${this:queuename}

> Wildfly supports Expression Substitution in descriptors [1]. These expressions are server global.
> This should be enhanced to support application scoped expressions:
> ${this:aProperty}
> It would be especially useful for Message Driven Beans, as an ActivationConfigProperty can only be set in a descriptor or via an annotation, but not in application code, so ActivationConfigProperties are effectively fixed.
> Then you could deploy the same Message Driven Bean multiple times with a different name:
> myMDB1.ear
> myMDB2.ear
> having 
> <activation-config-property-value>${this:queuename}</activation-config-property-value>
> and define
> <application-properties>
> <application name="myMDB_DEV_QUEUE_1.ear">
>  <property name="queuename" value="DEV_QUEUE_1"/> 
> </application>
> <application name="myMDB_DEV_QUEUE_2.ear">
>  <property name="queuename" value="DEV_QUEUE_2"/> 
> </application>
> </application-properties>
> whereas for production the queuename properties would be different.
