Context: JBoss 3.0.4

We discovered that if within a ejb application one entity bean happens to miss the findByPrimaryKey method, then two things occur. First, on deploy, the right message about the wrong EJB is displayed,i.e. it reports that the findByPrimaryKey method is missing, but the log identifies the wrong EJB. Second, the application (contained in an ear) appears to deploy beyond that, and does run, until you try to use some of the entity beans.
