You use the <cferror> tag to specify how error messages should be displayed. Customizing the error messages that appear throughout your application is generally a two-step process:
First, you create an error display template, which displays the error message along with whatever graphics or other formatting you consider appropriate.
Next, you include a <cferror> tag that tells ColdFusion to display errors using the error display template you just created. In general, you place the <cferror> tag in your Application.cfc file.
