First, select the Java Applet
you would like to add to your site. Download each of the necessary .class
files along with the appropriate image and audio files, if applicable.
(Note: Due to a bug in Communicator, you must hold down the shift key and
then click the link to download class files.) Another alternative would
be downloading the .java source code and compiling it using the
Java Compiler that is included with the Sun Microsystems Java
Developers Kit.
-
Next, make a note of the HTML
source, (usually, the source is included on the applet page for you to
copy), and copy the syntax (changing the <APPLET> and <PARAM> tags
as desired) into your HTML document.
-
Move the .class or .jar
file(s) into the appropriate directory (the path indicated in the CODEBASE=
portion of the <APPLET> tag, or the directory of your HTML document
if no CODEBASE= is specified).
-
If the Applet requires image
and/or sound files (generally .gif, .jpg, and .au
files), place them in the appropriate directories as indicated on the applet
page.
-
You are now ready to test the
Applet using the Sun Microsystems Applet Viewer (also included in the Java
Developers Kit) or a Java-enabled browser.
-
Finally, crediting the author
of the Applet on your page would probably be a nice finishing touch. Feel
free to use the following code to incorporate the credit part into your
page:
<a href="http://www.domainnameofjavaapplets.com">
<img alt="Title of the Java Applet Site"
src="http://www.domainnameofjavaapplets.com/imagesource.gif">
</a>
Note: The <img> tag is optional. You can substitute a text line instead.
Troubleshooting
If you see "Applet can't
start: class ______ not found" in your browser's status line, it can mean
one of two things:
-
The .class file(s) are not named
correctly. Java is case-sensitive, so be sure to follow precise capitalization.
-
The .class file(s) are not in
the correct directory. They should be located in the path indicated in
the CODEBASE= portion of the <APPLET> tag, or the directory of your
HTML document if no CODEBASE= is specified.
To further enable you to locate
the problem, you may start the Java console (under MSIE or NS). If you're
using Netscape, you'll find it under the Communicator item in the Netscape
menu (Java Console). Using MSIE, you'll find it under View (Java Console)
in the MSIE menu. The Java Console will give you more details than the
status bar, and may help you find out why the applet will not run. Often,
it will show you that the applet depends on more than one class file, and
you'll need to upload that class file to your server as well.
The applet may be written
for a newer JDK than you have on your system. Most applets will work with
MSIE4, and Netscape4 as well, provided you have applied the latest JDK
1.1 patch from http://developer.netscape.com.
