Foil 39 Wrapping Existing Applications -I

From General NPAC Foils-98A starting January 98 (PowerPoint) DSWA HPCC REquirements Workshop TASC Building Rosslyn VA -- 20 February 98. by Geoffrey C. Fox
CORBA is natural distributed object formalism
Java (with visual interfaces i.e. JavaBeans) is natural interface language
  • JavaBeans can be used at tier 1(client) or 2(server)
Linking this to tier 3 "classic applications" gives rise to JavaBean/CORBA wrappers for existing applications
This turns legacy applications into CORBA distributed objects and so can be remotely executed and documented (via CORBA trader or yellow pages service)
Further these applications now have a visual interface for linking them together in containers and inspecting their parameters
