Description

Used in a cfform tag, cfapplet lets you reference custom Java applets that you have registered using the ColdFusion Administrator.

To register a Java applet, open the ColdFusion Administrator and click Applets.

Syntax

<cfapplet appletSource = "applet_name"
  name = "form_variable_name"
  height = "height_in_pixels"
  width = "width_in_pixels"
  vSpace = "space_above_and_below_in_pixels"
  hSpace = "space_on_each_side_in_pixels"
  align = "Left" or "Right" or "Bottom" or "Top" or "TextTop" or "Middle"
    or "AbsMiddle" or "Baseline" or "AbsBottom"
  notSupported = "message_to_display_for_nonJava_browser"

notSupported
Optional. The text to display if a page containing a Java applet-based cfform control is opened by a browser that does not support Java or has Java support disabled. For example:
notSupported = "Browser must support Java to view ColdFusion Java Applets"
By default, if no message is specified, the following message displays:
Browser must support Java to view ColdFusion Java Applets!

paramn
Optional. The name of a registered parameter for the applet. Specify a parameter only to override parameter values already defined for the applet in the ColdFusion Administrator.

Usage

Since Java applets must be pre-registered, the cfapplet tag can be very simple, taking the default parameter values as they were registered in the ColdFusion Administrator. You can also override parameters by invoking them in the cfapplet tag.

and click the "Applets" link under the "extensions" section.
<P>This example applet copies text that you type into
a form. Type some text, and then click "copy" to see
the copied text.
