Parameters

Parameter

Description

type

Type of object to create.

  • com
  • corba
  • java
  • component
  • webservice
context
  • IOR: ColdFusion uses IOR to access CORBA server
  • NameService: ColdFusion uses naming service to access server. Valid only with the InitialContext of a VisiBroker ORB.
class
  • If context = "ior": absolute path of file that contains string version of the Interoperable Object Reference (IOR). ColdFusion must be able to read file; it should be local to ColdFusion server or accessible on network
  • If context = "nameservice": forward slash-delimited naming context for naming service. For example: Allaire//Doc/empobject.
locale

The name of the Java config that holds the properties file. For more information, see Configuring and Administering ColdFusion.

Usage

In the class parameter, if "context=NameService", use a dot separator for the first part of the string. Use either of the following formats:

  • "/Eng/CF"
  • ".current/Eng.current/CF"

ColdFusion supports CORBA through the Dynamic Invocation Interface (DII). To use this function with CORBA objects, you must provide the name of the file that contains a string version of the IOR, or the object's naming context in the naming service. You must provide the object's attributes, method names and method signatures.

This function supports user-defined types (structures, arrays, and sequences).

Example

myobj = CreateObject("corba", "d:\temp\tester.ior", "ior", 
    "visibroker") //    uses IOR

myobj =     CreateObject("corba", "/Eng/CF", "nameservice", 
    "visibroker")    // uses nameservice

myobj =     CreateObject("corba", "d:\temp\tester.ior", "nameservice")
       // uses nameservice and default configuration
