Chapter 7.  Integrating ColdFusion MX... >  Using External Objects in ColdFusi...

Using External Objects in ColdFusion

There are four major types of external objects that you can use from ColdFusion MX applications. These external objects are as follows:

  • COM objects. COM (Component Object Model) is a specification and a set of services defined by Microsoft to enable component portability, reusability, and versioning. DCOM (Distributed Component Object Model) is an implementation of COM for distributed services, allowing access to components residing on a network.

  • CFX tags. CFX tags are custom tags written in C++ or Java using the ColdFusion Application Programming Interface (CFAPI). These tags can be used just like any other ColdFusion tags once they’re registered in the ColdFusion Administrator.

  • CORBA objects. CORBA (Common Object Request Broker Architecture) is a specification for a distributed component object system defined by the Object Management Group (OMG). 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.

  • Java objects. Java objects include the Java classes available in the class path specified on the ColdFusion Administrator JVM and Java Settings page.
