Hi Matt, i would read all named Queries presents in my SessionFactory. I do not know how to retrieve this information using a entity manager. (....Someone know a trick for this??...) When I read your message, I thought you can use your solution. Read in the ClassMetadata, the names of persistent classes, to search for entries named Queries You wrote: - I can get a list of all PUs from JNDI, as well as references to the SessionFactory or EntityManagerFactory objects. - I can get a list of all entity classes in each PU by calling SessionFactory.getAllClassMetadata() on the SessionFactory for each persistence unit. How? Thanks in advance Fiorenzo View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4177749#...
