Michael Yuan commented on JBIDE-702:
------------------------------------

Max,

To answer your question in email: Yes, there is always a java:/DefaultDS in JBoss AS. It points to the bundled HSQL by default and the JDBC driver is already in the classpath.

However, the bundled HSQL is not accessible from outside of the AS. In fact, it is wiped clean with each server re-start. So, there is little point running "generate-entities" against it. Instead, the app will just map objects to DB tables -- it is the dev mode people use very often. Perhaps we should just disable generate-entities when the connection profile is not set. Thanks.

cheers
Michael

> Suggestion from Yuan is that if users doesn't specify any connection preferences we should use the defaultDs.
> Issues I see with this is that then our project will no longer "control" the datasource and what connection properties that is in it ?
> when we add generate-entities it should pick up what connection data is relevant.
> Which one will be the master ? today in seam-gen it is spread out and I don't like to make that worse...
> e.g. in seam-gen there is 
> 1) the actual datasource in jboss
> 2) the connection properties in build.properties
> 3) the connection properties in hibernate.console properties
> None of these are reliably possible to keep in sync afaik - neither manually or automatically
