Embedding Java applets

The cfapplet tag lets you embed Java applets either on a ColdFusion page or in a cfform. To use cfapplet, you must first register your Java applet using the ColdFusion MX Administrator Java Applets page (under Extensions). In the Administrator, you define the interface to the applet, encapsulating it so that each invocation of the cfapplet tag is very simple.

The cfapplet tag within a form offers several advantages over using the HTML applet tag:

• Return values Since cfapplet requires a form field name attribute, you can avoid coding additional JavaScript to capture the applet's return values. You can reference return values like any other ColdFusion form variable: Form.variablename.
• Ease of use Since the applet's interface is defined in the Administrator, each instance of the cfapplet tag in your pages only needs to reference the applet name and specify a form variable name.
• Parameter defaults ColdFusion uses the parameter value pairs that you defined in the Administrator. You can override these values by specifying parameter value pairs in cfapplet.

When an applet is registered, you enter just the applet source and the form variable name:

<cfapplet appletsource="Calculator"
   name="calc_value">

By contrast, with the HTML applet tag, you must declare all the applet's parameters every time you want to use it in a ColdFusion page.
