Hi. Using OpenJPA 2.1.1, I ran into this problem after I switched to custom implementation of the data source. I guess what's happening is that dictionary can no longer be determined from the class name, so it attempts to look at the URL, but the data source object is not yet populated. Everything works perfectly if I use original data source. Anything I can do? The database is postgres.
