1186 Part V . Putting JavaScript to Work Faceless applets Until LiveConnect came along, Java applets were generally written to show off data and graphics to play a big role in the presentation on the page. But if you prefer to let an applet do the heavy algorithmic lifting for your pages while the HTML form elements and images (or Dynamic HTML facilities of newer browsers) do the user interface, you essentially need what I call a faceless applet. The method for embedding a faceless applet into your page is the same as embedding any applet: Use the tag. But specify only 1 pixel for both the HEIGHT and WIDTHattributes (0 has strange side effects). This setting creates a dot on the screen, which, depending on your page s background color, may be completely invisible to page visitors. Place it at the bottom of the page, if you like. To show how nicely this method can work, Listing 44-4 provides the Java source code for a simple applet that retrieves a specific text file and stores the results in a Java variable available for fetching by the JavaScript shown in Listing 44-5. The HTML even automates the loading process by triggering the retrieval of the Java applet s data from an onLoad event handler. Listing 44-4: Java Applet Source Code import java.net.*; import java.io.*; public class FileReader extends java.applet.Applet implements Runnable { Thread thread; URL url; String output; String fileName = Bill of rights.txt ; public void getFile(String fileName) throws IOException { String result, line; InputStream connection; DataInputStream dataStream; StringBuffer buffer = new StringBuffer(); try { url = new URL(getDocumentBase(),fileName); } catch (MalformedURLException e) { output = AppletError + e; } try { connection = url.openStream(); dataStream = new DataInputStream(new BufferedInputStream(connection)); while ((line = dataStream.readLine()) != null) { buffer.append(line + n ); } result = buffer.toString(); }
