  1. Programming Heterogeneous Systems with CORBA By Rick Szatkowski

  2. Introduction • What is CORBA? • Common Object Request Broker Architecture • Defines APIs, communication protocol, and object/service information models to enable heterogeneous applications written in various languages running on various platforms to inter operate.

  3. Why use CORBA? • Using the standard protocol IIOP, a CORBA-based program from any vendor, on almost any computer, operating system, programming language, and network, can interoperate with a CORBA-based program from the same or another vendor, on almost any other computer, operating system, programming language, and network.

  4. Acronyms • ORB • Object Request Broker • OMG • Object Management Group • IDL • Interface Definition Language • OBV • Objects by Value • CCM • CORBA Component Model • IIOP • Internet Inter-Orb Protocol

  5. CORBA Process

  6. Problem Description • Create an application that shows the capabilities of CORBA using the IDL to work cross different languages. • This application will also need to be able to operate on various operating systems. • There will be both a client and server version of this application. • This client and server will also be written in different languages and operate on separate operating systems.

  7. Solution • Create a Client using Java • Create a Server using Java • Create a Client using C++ • Create a Server using C++ • Run Client and Server on Linux • Run Client and Server on Windows

  8. Solution (cont.)

  9. Solution (cont.) • Clients shall have several different commands to pass objects and variables • Clients shall be able to connect to different servers • Servers shall accept clients from multiple languages and operating systems

  10. Results • Working Java Client • Working Java Server • Demonstration

  11. Conclusion • I still have much work to accomplish • Having some major difficulty with the servertools but have gotten the IDL to work on an internal network

  13. Questions Where can I get a hat like that?
