Description

This tag references a registered custom Java applet. To register a Java applet, in the ColdFusion Administrator, select Extensions > Java Applets. Using this tag within a cfform tag is optional. If you use it within cfform, and the method attribute is defined in the Administrator, the return value is incorporated into the form.

Syntax

<cfapplet 
appletSource = "applet name"
