  • How evil are Data Transfer Objects (DTOs)?
  • In certain situations, they become the necessary tool or workaround to solve a particular problem
  • Some relations are probably going to be collapsed, attributes renamed and even types changed
  • ...1 more annotation...
  • It is perfect valid to introduce a dedicated DTO to adapt an incompatible domain layer

  • Does GraniteDS could manage date and TimeZone ?
  • Flash Player (GMT +X) -> IExternizable methods (GMT + X - X = GMT + 0) - > AMF over HTTP (GMT + 0) -> Granite AMF0Deserializer (GMT + 0) -> Granite Converter (GMT + 0 + Y = GMT + Y) -> Java Services (GMT + Y)Java Services (GMT + Y) -> Granite Converter (GMT + Y - Y = GMT + 0) -> Granite AMF0Deserializer (GMT + 0) -> AMF over HTTP (GMT + 0) -> IExternizable methods (GMT + 0 + X = GMT + X) -> Flash Player (GMT + X)
  • We use
  • GMT + 0
  • for AMF for convention
  • define a
  • fixed timezone
  • for your AMF that is over HTTP
  • GMT + X
  • : timezone for your flex client
  • GMT + Y
  • : timezone for your server
  • don't want to modify the default templates
  • override the readExternal / writeExternal methods and do the conversion here.
  • The patch is to use a custom template for generating your as files with a conversion to GMT 0 in the implementations of IExternalizable methods.On the server-side you add a Converter to convert dates GMT 0 to dates GMT + Y.

      see better suggestion below (ie. override instead of replace)
