CORBA is a standard for distributing objects across networks so that operations on those objects can be called remotely. CORBA is not associated with a particular programming language, and any language with a CORBA binding can be used to call and implement CORBA objects. Objects are described in a syntax called Interface Definition Language (IDL).
CORBA includes four components:
- Object Request Broker (ORB)
- The Object Request Broker (ORB) handles the communication, marshaling, and unmarshaling of parameters so that the parameter handling is transparent for a CORBA server and client applications.
- CORBA server
- The CORBA server creates CORBA objects and initializes them with an ORB. The server places references to the CORBA objects inside a naming service so that clients can access them.
- Naming service
- The naming service holds references to CORBA objects.
- CORBARequest node
- The CORBARequest node acts as a CORBA client.
The following diagram shows the layers of communication between IBM® Integration Bus and CORBA.
The diagram illustrates the following steps.
- CORBA server applications create CORBA objects and put object references in a naming service so that clients can call them.
- At deployment time, the node contacts a naming service to get an object reference.
- When a message arrives, the node uses the object reference to call an operation on an object in the CORBA server.
