After you register an applet, you can use the cfapplet tag to place the applet in a ColdFusion page. The cfapplet tag has two required attributes: appletsource and name. Because you registered the applet and you defined each applet parameter with a default value, you can invoke the applet with a very simple form of the cfapplet tag:

<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 cfapplet parameters to specify custom values. For example, the following cfapplet tag specifies custom spacing and 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">
