Hi scout1lacno, I am having a named query issue and came across your post. Would you mind telling me where you defined your named query: with the entity or within your bean class? I defined my namedquery with the entity. I am using jboss-4.0.5 with EJB3 so I have not had to deal with mapping files or anything else. But I am getting a hibernate mapping exception "Named query not known". Any ideas at all? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4037643#...
