• While transferring huge amount of data or values between two layers of application instead of sending between two layer multiple number of time its is recommended to combine all these multiple values into single object and sends that object to destination layer
  • due to this round trips between layers will be received and sending and receiving values will become easy in struts application, form page view layer use multiple values as form data for action class
  • all these values will combined into form bean class object and will be made visible in model layer action class in two forms of single object due to this we can say form bean class is action data transfer object or value object class
