OK, I did a little debugging inside JBoss and confirmed that the HQL statement causing the exception was this one: | from EscalationGroup as escGrp where escGrp.class = com.cpicorp.roster.objects.EscalationGroup order by escGrp.description | It looks like the error is being thrown when it's resolving the fully qualified classname (com.cpicorp.roster.objects.EscalationGroup) in | where escGrp.class = com.cpicorp.roster.objects.EscalationGroup | I removed the package name to make the HQL read | from EscalationGroup as escGrp where escGrp.class = EscalationGroup order by escGrp.description | And this works fine now. Is this a bug? It seems that a fully qualified classname should be accepted. The fully qualified name worked under whatever version comes with JBoss 4.0.4GA.
