Displaying a file located on a server: The URL example
Java Get Powered

The applet can be configured to fetch the drawn RNA from the internet, by mean of the url parameter. This feature is illustrated in the above example, where four structures are respectively loaded from applet parameters (NW), from the local HTTP server (NE and SW) and from the NDB server (SE). Also, it is noteworthy that three different formats are being used here.

Note to Firefox users: Certain versions of Firefox may be confused by self-signed certificates, and silently prevent the applet from running. If the frame above shows up empty, then try reloading the page.
