Getting Started with CORBA Objects

CORBA is the Common Object Request Brokerage Architecture, a specification for a component object system. ColdFusion Enterprise version 4.0 supports CORBA, through the Dynamic Invocation Interface (DII).

ColdFusion Enterprise version 4.0 is bundled with deployment software from VisiBroker for C++ 3.2. These runtime DLLs are used to invoke operations on object references made available using the CFOBJECT tag.

A directory for logging output from VisiBroker is created when you first start ColdFusion Server, Enterprise edition. This directory is called vbroker\log and its location is determined as follows:

  1. If VisiBroker is already installed on the server, the log directory is the directory pointed to by the VBROKER_ADM environment variable.
  2. If this is a new VisiBroker installation, the log directory is created on the root of the drive from which ColdFusion Server is started. For example, if ColdFusion is installed in c:\cfusion or opt/coldfusion (Solaris), then the log directory will be c:\vbroker\log or /vbroker (Solaris).
  3. If the creation of the log directory on the root fails, then the directory is created in the ColdFusion installation directory.

Note

User-defined types are not supported (i.e., structures).

Using CFOBJECT to create a CORBA object

In the CFOBJECT tag, several key attributes are required for calling CORBA objects:

See the CFML Language Reference for information about the CFOBJECT tag as well as examples of CFOBJECT tag creating a CORBA object.
