Implementation

The BC4J-VSM is implemented in three JDeveloper projects:

  • VSMWebapp, which implements the end-user UI and performs actions when users submit forms.
  • VSM_JClient, which implements the admistrator's interface.
  • VSM-BC4J, which implements BC4J objects that represent real-world entities such as users, shops, items, and orders.
