Chapter 5: Building Blocks of ColdFusion

Applications

You can create ColdFusion elements to organize your code. When you create any of these elements, you write your

code once and use it, without copying it, in many places.

About CFML elements that you create

Adobe ColdFusion provides you with several techniques and elements to create sections of code that you can use

multiple times in an application. Many of the elements also let you extend the built-in capabilities of ColdFusion.

ColdFusion provides the following techniques and elements:

• ColdFusion pages you include using the

• User-defined functions (UDFs)

• ColdFusion components

• Custom CFML tags

• CFX (ColdFusion Extension) tags

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

Applications" on page 1125.

• Java objects, including objects in the Java run-time environment and JavaBeans. For information on using Java

objects, see

"Integrating J2EE and Java Elements in CFML

• Microsoft COM (Component Object Model) objects. For information on using COM objects, see

COM and CORBA Objects in CFML

• CORBA (Common Object Request Broker Architecture) objects. For information on using CORBA objects, see

"Integrating COM and CORBA Objects in CFML

• Web services. For information on using web services, see

Including pages with the cfinclude tag

tag adds the contents of a ColdFusion page to another ColdFusion page, as if the code on the included

page was part of the page that uses the

ColdFusion elements that you incorporate in multiple pages. Instead of copying and maintaining the same code on

multiple pages, you can store the code in one page and then reference it in many pages. For example, the

tag is commonly used to place a header and footer on multiple pages. This way, if you change the header or footer

design, you only change the contents of a single file.
