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
1 CORBA is natural distributed object formalism
2 Java (with visual interfaces i.e. JavaBeans) is natural interface language
  • JavaBeans can be used at tier 1(client) or 2(server)
3 Linking this to tier 3 "classic applications" gives rise to JavaBean/CORBA wrappers for existing applications
4 This turns legacy applications into CORBA distributed objects and so can be remotely executed and documented (via CORBA trader or yellow pages service)
5 Further these applications now have a visual interface for linking them together in containers and inspecting their parameters
