So I guess that the Embeddable EJB container is not properly started, or else your jndi.properties is missing or does not contain the correct values. I am in the same boat as the other poster: this does not mean much to me either and I am familiar with EJB3. Could you clarify all the requirements for running unit tests? What libraries are needed, what files should be on the classpath and where, and so on. As far as I can tell, my configuration is nearly identical to that found in the example applications, I include all the same libraries, my build artifacts contain the same resource files, and so forth. I have been trying to pinpoint the cause but my efforts are fruitless. (See http://jboss.com/index.html?module=bb&op=viewtopic&t=89261 for some of my stack traces.) You say our JNDI properties (may) contain the wrong values. What should it contain? How is it referenced? How does the scaffold know about the datasource? What should the classpath contain? What does the scaffold actually use to run the tests? Should we be looking at the microcontainer configuration? The embedded-ejb configuration? (Note these have the same JNDI properties.) I am enjoying Seam a great deal. You guys have done a great job with this stuff, and I am pushing it like crazy where I work, but I really need some more details on debugging things like this. I will not and cannot proceed on projects without unit testing, making this the only blocker on projects coming down the pipeline.
