To run the Protégé-Frames applet demos, you must first install Sun's
Java Plug-in technology, which is part of the Java 2 Runtime
Environment (JRE). This plug-in supplies the correct version of Java for your browser to use with the applets. The
applets may take a minute or so to start on a machine with a fast internet connection.
You can browse and modify these examples to see how the tool works but you will not be able to save your changes.
