[jira] [Commented] (ARIES-1355) blueprint-jpa does not interpolate configuration properties

["Christian Schneider (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARIES-1355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14638377#comment-14638377 ] 

Christian Schneider commented on ARIES-1355:
--------------------------------------------

As far as I know configuration properties can only be used for bean property values. I am not sure if there are plans to allow property values at other places.
I would rather consider that a general issue for blueprint but I am not sure if it is planned to allow properties in additional places. 

Btw. in aries jpa 2 there is no jpa:unit element anymore. The persistence unit name is set using an annotation only.

> When attempting to wire in the persistent unit name from a cm property, aries jpa does not interpolate the value, and instead tries to lookup the ${name} literally.
