The Discriminator's are not specified only in the 'SINGLE_TABLE' strategy. it is possible to use into join strategy. i have book "Pro EJB3 Java Persistence API" (Mike Keith and Merrick Schincariol) http://www.amazon.com/Pro-EJB-Java-Persistence-API/dp/1590596455 on page 249 is defined joined strategy and tehere is data model in example Employee, FullTimeEmployee,PartTimeEmployee and ContractEmployee using Joined Strategy. find out here Example 1-74 http://www.oracle.com/technology/products/ias/toplink/jpa/resources/topli...
