I can't say what it is, but definitely something Derby-related.
Googling the exception shows quite a few hits. Which connection pool
you end up using anyways? The built in Cayenne version?

Awesome; that's exactly what I was looking for.
I'm getting an exception I don't quite understand, now. Cayenne is
complaining about having "no current connection," but it has already
performed a single query and received results!

Subject: Re: How can I customize the driver/url/login
In the Modeler there is a dropdown for the DataNode called "DataSource
Factory". Here you can specify your own class that implements
"org.apache.cayenne.conf.DataSourceFactory" interface. Your own
factory can implement 'getDataSource' method to pop up a dialog asking
user to enter DB info on first call, or do whatever is appropriate in
your case.
Cheers,
Andrus
