Radhika, I'm also kinda a struts newbie, so don't take this as the word of an expert!
In a recent project that I did, I used FormBeans as wrappers over Value Objects. I found some strong points to this kinda design: - Separation of view related and biz logic issues -- The Action class calls into the Session Layer, gets a DTO/VO, Inits a FormBean. -- The Action class retrieves an updated DTO from a FormBean, and calls into the Session Layer to update the Biz layer - Separation of 'Presentation' level validation (is a field blank, does it contain a valid float etc.) from Biz level validation (is field1*field2 < field3/1.5 etc) -- Essentially, the FormBean does the Presentation level validation, and then delegates to the DTO, which could do lightweight Biz validation. -- The ActionErrors stuff is all taken care of within the FormBean. For Presentation level validation errors, the FormBean has control anyways. For Biz level validation errors, The DTO can throw a ValidationException which the FormBean catches and takes care of by adding to ActionErrors. I'm waiting for Chapter 7 of Chuck's book (On theServerSide.com) to read up more on this ;) Hope this helps, - Lalit ----- Original Message ----- From: "Radhika Nadkarni" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, May 24, 2002 2:35 AM Subject: Value object doubt !!! > hi, > Im having an action Form.
