Save the file in the testapplet folder with the file name of java.html. You are not yet
ready to test the page—you need to create and format the text file that the applet
expects. This applet expects each line of text to begin with text= . Figure 11.15
shows a sample text file created using Notepad.

Use this as a guide to create your text file. Save your text file as mymessage.txt in the
testapplet folder. The name of the text file must match the value of the “Data” parameter
in the XHTML code. Now launch your page in a browser. The applet should display
your text one line at a time (Your browser may display a warning message about the

This Java applet displays a message one line at a time. Message:
This is a Java applet. This displays text one line at a time.
Why doesn't my Java applet work?
If your applet does not function as expected, verify the following:
Are Java applets enabled in your browser?
Is the applet saved in the testapplet folder?
Is the applet saved with the name fader26.class (all letters must be in lowercase)?
Are the java.html and mymessage.txt files saved in the testapplet folder?
Does the code attribute on the <applet> tag have the value of fader26.class?
Be aware that the disadvantage of using Java applets is the lag between the time the Web
page is initially loaded and the time the applet actually begins to execute. Your Web page
visitor will see a box in the area reserved for the applet until it begins executing.
