basic CRUD (Create‚ Retrieve‚ Update and Delete). This application is called MyUsers‚ which will be the sample application throughout the book. It’s a 3tiered webapp‚ with an Action that calls a business delegate‚ which in turn calls a Data Access Object (DAO). The diagram below shows a brief overview of how the MyUsers application will work when you finish this tutorial. The numbers below indicate the order of flow – from the web (UserAction) to the middle tier‚ (UserManager)‚ to the data layer (UserDAO)

after it’s ceased to exist‚ nor is it possible for the replacement part to have been in existence before it was ever created. However‚ Reid’s imperfect identity theory suggests that if an object is changed and there is no persisting identity‚ but it holds the same qualities and characteristics of the previous object‚ one can call it the same thing for the sake of convenience. Though Reid hadn’t

distributed object systems where communication between program- level objects residing in different address spaces is needed. In order to match the semantics of object invocation‚ distributed object systems require remote method invocation or RMI. In such systems‚ the programmer has the illusion of invoking a method on an object‚ when in fact the invocation may act on a remote object (one not resident in the caller’s address space). In order to support distributed objects in Java‚ we have
