Hi,

I looks like there's one bug in the example.

jboss-web.xml defines jdbc/MyDS

But persistence.xml references java:comp/env/MyDS

Shouldn't the last one be at least java:comp/env/jdbc/MyDS? Regardless, even with matching names it indeed doesn't work.

Kind regards,
Arjan Tijms

WFLY-2841 reports a deployment failure that occurs when a deployments

service dependency that is added to the persistence unit service [5],
instead of resolving the resource reference (and using the underlying
DataSource).

How should we handle resource references for this case?  Is there a way
to resolve the resource reference directly from deployers?  Or do we
represent the resource reference as a service?
