    [ http://jira.jboss.com/jira/browse/JBAS-4942?page=comments#action_12386150 ] 
            
Michael Lipp commented on JBAS-4942:
------------------------------------

This is actually a clone of JBAS-4275.

The point missed in the comment by Adrian Bock on the original issue is that you cannot configure a resource adapter from outside an EAR if the RAR is inside the EAR and the EAR uses scoped classloading.

Another way to put this is: JBoss should support the specification of a loader repository in the deployment descriptor for datasources (jboss-ds_*.dtd).

Why is this important? I want to deliver my application as an EAR together with some installation hints for the person installing this. I want to avoid the EAR being unpacked and repacked again during installation (that's why putting the deployment configuration inside the EAR is not an option). Therefore I want to specify the configurable information related with the resource adapter (host adresses, credentials, ...) in a separate, independant deployment descriptor.

Currently I can do this only if I do not use scoped classloading in my EAR. Of course you can argue "this is not a bug, simply don't use scoped classloading". But scoped classloading is there for a reason, isn't it?
