I did not say you have to - I just say it was an option.
We don't enable Dali by default because there are issues with Dali's default behavior (e.g. not knowing what the right default schema on dbs)

It does not appear to work with a Seam project with JPA aspect added (in the JPA structure window the message "Structure is not available for the current selection" when selecting a class which is to be bound to a database table). The Dali tutorial works but requires a JPA project.

Yes - so you need to enable the JPA facet. Can be done at creation time in the wizard or right click on the project and add the facet under the facet preferences.

I don't understand ? Just use Seam Generate Entities...(which will setup the proper Hibernate tools setup)

Yes - welcome to the land of codegeneration...

So use Seam Generate Entities Wizard, but select "Use existing entities" instead of the "Reverse engineer from database"

anonymous wrote : 
  | Using seam-gen does not seem to work well, because it is all database tables or nothing, and gets the relationships wrong (not enough info in database schema to determine correct multiplicities and direction).

Yes - depending on what things you want to configure you can decide to use a .reveng.xml file to control these things very precise. 

Over time we will make this more easily available. See Hibernate tools for the docs about these things.

try generating from the enttiies instead...

Which example exactly ?

anonymous wrote : 
  | I am assuming/hoping that my confusion is simply due to a lack of documentation which will eventually be answered (or perhaps features which are not there but will be for GA), but I am still trying to figure the best way to do a simple application with a database that has multiple tables, with relationships.

Use Seam Generate Entities - but it is only something that generates the *basis* of an app.

this is what the seam-gen/Wizards are targeted at.

anonymous wrote : 
  | Pointers to an end-to-end project would be useful (something more than a one-table CRUD example).  If seam is the main focus of JBoss tools/RHDS, perhaps the examples in the Seam tutorial could be redone using these tools.

I don't recall any multi table examples in seam tutorial ? link ?

  | When JBoss Tools/RHDS really gets it together, it looks like it will be preferable to the NetBeans model which has the same architectural constraints that Sun Studio Creator had (each page has a backing bean that everything gets dumped into, etc.)

Yes - that is definitly not the way our tooling works - we belive in less constraints (but that also put some more responsiblity on to the programmer ;)
