The appletviewer command allows you to run applets outside of a web browser.
appletviewer

options
] urls
...
The appletviewer command connects to the documents or resources designated by urls and displays each applet referenced by the documents in its own window. Note: if the documents referred to by urls do not reference any applets with the OBJECT, EMBED, or APPLET tag, then appletviewer does nothing. For details on the HTML tags that appletviewer supports, see AppletViewer Tags.
Note: The appletviewer requires encoded URLs according to the escaping mechanism defined in RFC2396. Only encoded URLs are supported. However, file names must be unencoded, as specified in RFC2396.
