It's been a while, but let me see if I can remember what we did. I know I had to get the JNDI names correct (set it up in the components.xml, either hardcoded in a test resource, or let maven do the filtering). Then, yeah this step may seem very obvious, make sure you have the datasource XML file along with any of the other Embeddable container configuration files. That should pretty much do it (assuming you have the jars for the EEJB container). If you're having the same problem give a full stack track and exerts from your pom.
