Programming Heterogeneous Systems with CORBA

• By Rick Szatkowski

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.

CORBA Process

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.

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

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
