94 Chapter 5 Basic ColdFusion Server Administration
Java Applets
The Java Applets page of the Administrator lets you register applets and modify and
delete applet registrations. Before you can use Java applets in your ColdFusion
applications, you must register them in the Java Applets page.
When your applet is registered with ColdFusion Server, using the
cfapplet tag in
your CFML code is very simple, because all parameters are predefined. Simply enter
the applet source and the form variable name you want to use.
Note
Parameters set in the
cfapplet tag override parameters defined in the Java Applets
page.
To register a Java applet:
1 On the Java Applets page, click Register New Applet. The Add/Registered Applet
page displays.
2 Enter options for the following settings:
