I've been struggling with this problem all day, and I just figured out what my problem was. Maybe yours is the same. I too started with the examples, specifically booking. In my case, I had been checking the differences between my log output and the booking example test output, and the key difference was that my entity manager and datasource were never deployed. I spent some time on that, and I was on the right track. Check your jboss-beans.xml file, in META-INF. When running in the container, it seemed okay to leave this blank (or rather, with empty deployment tag). In the eejb/microcontainer environment, I needed some kind of datasource bootstrap, like in booking/resources/META-INF/jboss-beans.xml. Then of course I needed an import.sql to load the data I needed for the test(s), since I'm no longer connecting to Oracle. That did the trick for me. Hope this helps.
