Couple of things:

* make sure you comment this line:
String dbCreate = "update" // one of 'create', 'create-drop','update'

You dont want grails altering your schema :)

* Instead of groovy domain objects, create java domain objects with JPA annotations. Refer http://grails.codehaus.org/Hibernate+Integration

Hi All,

I'm fairly new to Grails/Hibernate - so hopefully this query isn't too
noobish.
Currently I'm in the middle of designing a web client to access a
database (previously accessed with a desktop client).  The only catch
is, there is significant data already in place that is reliant on
pre-existing tools - which means it's highly unlikely that I can
restructure the database in the near future.

Outside of changing the *DataSource.groovy files to point to the
relevant database (and provide user details), is there anything I would
need to be wary of in terms of using the existing database?  
For example, is it likely to cause problems that some "standard" fields
are not there (like id, version)?

Thanks!
