The "min" resource gives a runtime exception on deployment:

This on JBoss 4.2.2GA running against JDK 1.5.
Remove the @Resource annotation on the minCheckNumber and the bean deploys fine (so there's probably no error in the ejb-jar.xml or that would have caused a deployment failure all its own).
Am I missing an entry in jboss.xml that causes the ejb-jar entry to be skipped maybe? The book doesn't mention such an entry.
