Foil 110 Wrapping Existing Applications -I

From CORBA Common Object Request Broker Architecture Basic Information Track Computational Science Course CPS616 -- Spring Semester 1999. by Geoffrey Fox, Wojtek Furmanski, Nancy McCracken, Chao-Wei Ou, Shrideep Pallickara
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
