Hi all
I've written an ant task which reverse engineers a postgresql database
into JPA Annotated Entity classes for Hibernate/TopLink etc. So far so good.
For my next trick I want to reverse engineer null/not null and check
constraints into Spring Validator classes so I can do validation in the
web tier (and potentially as downloaded JavaScript in the browser). The
reason I want to have validation based on check constraints is that the
database will potentially be updated from other legacy applications.
I can't see any custom extensions to extract check constraints - are
there any?
If I'm barking up the wrong tree, or if there is a better approach
please feel free.
many thankis
Roy
