Developing ColdFusion MX Applications with CFML
Reusing Code in ColdFusion Pages

About reusable CFML elements

ColdFusion provides you with several types of reusable elements, sections of code that you can create once and use multiple times in an application. Many of these elements also let you extend the built-in capabilities of ColdFusion. ColdFusion provides the following reusable CFML elements:

• ColdFusion pages you include using the cfinclude tag
• User-defined functions (UDFs)
• Custom CFML tags
• CFX (ColdFusion Extension) tags
• ColdFusion components

The following sections describe the features of each of these elements and provide guidelines for determining which of these tools to use in your application. Other chapters describe the tools in detail. The last section in this chapter includes a table that helps you chose among these techniques for different purposes.

ColdFusion can also use elements developed using other technologies, including the following:

• JSP tags from JSP tag libraries

  For information on using JSP tags, see Chapter 32, "Integrating J2EE and Java Elements in CFML Applications".

• Java objects, including objects in the Java runtime environment and JavaBeans

  For information on using Java objects, see Chapter 32, "Integrating J2EE and Java Elements in CFML Applications".

• Microsoft COM (Component Object Model) objects

  For information on using COM objects, see Chapter 33, "Integrating COM and CORBA Objects in CFML Applications".

• CORBA (Common Object Request Broker Architecture) objects

  For information on using CORBA objects, see Chapter 33, "Integrating COM and CORBA Objects in CFML Applications".

• Web services

  For information on using web services, see Chapter 31, "Using Web Services"
