Hi, According to documentation, Hibernate supports java.util.TimeZone and java.util.Currency as persistence type. I wonder if EJB 3.0 supports them as well? If not, what is the best way to define timezone and currency as property in a Entity definition class? I googled those key words already, but have not got any useful idea yet. Thanks!
