How applets work

• An applet is a special type of application that can be downloaded from an Internet or intranet server and run on the client's computer within a web browser.
• The Java Plug-in is included as part of the JRE. It is a browser plug-in that allows a web browser to use a version of the JRE that's newer than the one that's included with the browser.
• For a client machine to run applets, a current version of the JRE and Java Plug-in must be installed on the client.
• If a user attempts to run an applet without first installing the current version of the Java Plug-in, a prompt will be displayed indicating that the Java Plug-in must be downloaded.
