What about a second datasource file? It is still present even without ticking JPA facet. By the way, I noticed that the project structure generated in Eclipse is slightly different from that generated by seam-gen, particularly what concerns production/development/testing configurations. I assume that test configuration is now separated into another project, but how to run development/production configuration in Eclipse, without using ANT?
