Hi, ��� I have an abstract class, Users, that is extended by several classes such as Administrator, Tester etc. My service method, LogIn, will return a User object upon successful login. I verify that a Users object is send back to the client. However, the client will throw an exception which indicate that a Java Bean can not be created because there is no default constructot for Users class.
��� This design is to hide the detail from the client program so that there is no testing logic for identifying the type of the user who logs in. Any suggestion�to resolve this issue is highly appreciated. Harry Wen
