Often, you will create applets that will need to explicitly load media and text Java will allow the applet to load data from the directory holding the HTML file that started the applet (the document base) and the directory from which the applet s class file was loaded (the code base) These directories are returned as URL objects (described in 20) by getDocumentBase( ) and getCodeBase( ) They can be concatenated with a string that names the file you want to load To actually load another file, you will use the showDocument( ) method defined by the AppletContext interface, discussed in the next section The following applet illustrates these methods:

One application of Java is to use active images and animation to provide a graphical means of navigating the Web that is more interesting than simple text-based links To allow your applet to transfer control to another URL, you must use the showDocument( ) method defined by the AppletContext interface AppletContext is an interface that lets you get information from the applet s execution environment The methods defined by AppletContext are shown in Table 21-2 The context of the currently executing applet is obtained by a call to the getAppletContext( ) method defined by Applet Within an applet, once you have obtained the applet s context, you can bring another document into view by calling showDocument( ) This method has no return value and throws no exception if it fails, so use it carefully There are two showDocument( ) methods The method showDocument(URL) displays the document at the specified URL The method showDocument(URL, String) displays the specified document at the specified location within the browser window Valid arguments for where are _self (show in current frame), _parent (show in parent frame), _top (show in topmost frame), and _blank (show in new browser window) You can also specify a name, which causes the document to be shown in a new browser window by that name The following applet demonstrates AppletContext and showDocument( ) Upon execution, it obtains the current applet context and uses that context to transfer control to a file called Testhtml This file must be in the same directory as the applet Testhtml can contain any valid hypertext that you like
