Using COM and CORBA Objects

ColdFusion supports COM and CORBA objects through the CFOBJECT tag. COM (Component Object Model) is an architecture defined by Microsoft to enable component portability, reusability, and versioning. OLE, for example, is an implementation of COM. DCOM (Distributed Component Object Model) is an implementation of COM for distributed services, allowing access to components residing on a local network or anywhere on the Internet.

COM objects can reside locally, or on any other machine on the network, or on other networks. Currently, COM is supported on Windows NT and Windows 95/98.

About CORBA

CORBA (Common Object Request Broker Architecture) is a specification for a distributed object system. In this model, an object is an encapsulated entity whose services are accessed only through well defined interfaces. The location and implementation of each object is hidden from the client requesting the services. ColdFusion supports CORBA 2.0 on both Windows and Solaris.

The main features of CORBA 2.0 are:

You access CORBA objects through the CFOBJECT tag. An Object Request Broker (ORB) is required. Popular ORBs include Visibroker, Orbix, and CorbaPlus.

For more information, see Getting Started with CORBA Objects in this chapter.
