I have a class that I am populating from a Query like this: List<CurrencyAmount> currencyAmounts = entityManager.createQuery("select new com.locuslive.odyssey.amount.CurrencyAmount(la.currency, sum(la.chargeAmount)) from LineAmount ...etc If I put this CurrencyAmount class into WEB-INF/dev then Hibernate cannot find it. org.hibernate.hql.ast.QuerySyntaxException: Unable to locate class [com.locuslive.odyssey.util.CurrencyAmount] Moving the class to a package that isn't hot deployed fixes this. Bug or Feature? Cheers, Damian. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4069244#...
