I agree. I don't think mapping a datasource in jboss-web.xml is
such an exotic use case. I should just work.
It’s not, it’s actually implied by the standard, as you can define them in web.xml as
well. It’s a lifecycle problem we need to solve.
Also, there is no hint anywere that there is a property you can set
to make it work.
The proprietary jboss namespace is not an option since I want to be vendor neutral, but
ear/java:app is definitely an option.
Another solution specific to EE7 is you can leave the jta-data-source undefined in
persistence.xml which will use the platforms default data source. We allow you to point
that anywhere. However, that limits you to one, so not really a complete solution.
A more complete solution is to use a common global name, and define an alias to your
deployment in our naming subsystem like so:
<bindings>
<lookup name="java:global/env/FooDS"
lookup="java:jboss/datasources/ExampleDS"/>
</bindings>
