ADF Swing doesn't talk directly to the database. ADF Swing goes through
the ADF databinding layer, which in turn talks to the business services
which do the actual database access. So, it's not a question of whether
ADF Swing supports SQLite, it's a question of whether the business
service you are binding to supports it. In the case of this customer,
they are using ADF BC as the business service, which does not currently
certify against SQLite, but it is generically supported as a 3rd party
SQL92-compliant database. I've responded to the other thread on that
topic as well.

I know that there is an effort underway to make JDeveloper work with SQLite (separate team from mine, don't know details), but I have no idea if there is any effort underway to make ADF Swing work with SQLite. This is possibly a new requirement for that group.
