Connecting to a database from within JBDS/Eclipse is a multi-step, multi-screen, potentially error-prone challenge.

Forge is involved as it can generate entities from schema
Datasources are needed in/on AS/Wildfly/EAP in order for the project deploy
Persistence.xml may needed to be tweaked for the datasource
End-user would like to navigate the schema in the DTP/Hibernate Tools, interactively review the data and there was once a feature for viewing an ORM diagram that I seem to have forgotten how it is displayed.

What happens when a project that needs a database connection is imported into the IDE?

This was partially addressed with
https://issues.jboss.org/browse/JBIDE-15263

Let's see if we can continue to improve the workflow by reducing steps, making it more obvious what steps are required (e.g. hey developer, get the mysql driver .jar), auto generating the -ds.xml, with a decent explanation for the end-user to follow.
