Default data sources is one of the new features of Java EE 7 and I think its worth showcasing how apps can be simplified with that. I'll let you decide upon resource/time but its useful IMHO.

Hi Arun!

Wildfly archetypes are created based on Quickstarts (just as Rafael mentioned here [1]). 
In case of wildfly-javaee7-webapp-blank-archetype it is kitchensink [1]. Quickstarts are designed in such a way, that they can be deployed all together (this is why they need separate datasources). 

So, test-ds.xml is a design consequence of how Quickstarts are embedded into archetypes. In my opinion we won't be able to get rid of it. Alternatively we could refactor all quickstarts to use default database - which might be pretty time consuming.

Best regards

For Java EE 7, a default data source is available if none is specified
in persistence.xml. In WildFly, this is mapped to ExampleDS already.

Does test-ds.xml create a new data source, or map to an existing one ?
