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