Using the cfapplet tag to embed an applet
After you register an applet, you can use the
has two required attributes:
parameter with a default value, you can run the applet with a simple form of the
<cfapplet appletSource="appletname" name="form_variable">
Overriding alignment and positioning values
To override any of the values defined in the ColdFusion Administrator for the applet, you can use the optional
parameters to specify custom values. For example, the following
cfapplet
alignment values:
<cfapplet appletSource="myapplet"
name="applet1_var"
height=400
width=200
vspace=125
hspace=125
align="left">
Overriding parameter values
You can override the values that you assigned to applet parameters in the ColdFusion Administrator by providing new
values for any parameter. To override a parameter, you must have already defined the parameter and its default value
in the ColdFusion Administrator Applets page. The following example overrides the default values of two parameters,
Param1 and Param2:
<cfapplet appletSource="myapplet"
name="applet1_var"
Param1="registered parameter1"
Param2="registered parameter2">
Handling form variables from an applet
The tag attribute corresponds to a variable in the action page, Form.appletname, which holds any value

that the applet method returns when it is executed in the
