             Summary: per application Expressions
                 Key: WFLY-8868
                 URL: https://issues.jboss.org/browse/WFLY-8868
             Project: WildFly
          Issue Type: Feature Request
            Reporter: Juergen Weber
            Assignee: Jason Greene


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.
