Java Archives in Java 1.2
A single Java program can have dozens of source files. The Java archive (JAR) simplifies distribution for the programmer and makes applets download much faster to the user. We explain how to create JAR files and what syntax to use for Java 1.2 and HTML 4.0 while keeping backward compatibility with older browsers.

By William Robert Stanek

Like most technologies for the Web, Java is a fast-moving target, and just about the time you think you have this stuff all figured out, someone somewhere changes the rules. Sure, all the changes are meant to make the Web faster and more fun, but change requires an effort.

We'll take a look at the new ways Version 1.2 and HTML 4.0 let you work. You'll find out how to create archive files and use them to simplify distribution of Java programs. We'll also examine a new HTML tag strategy for use with archives. Even if you aren't a programmer, you'll be able to use this information to enhance your Web site's use of Java.

William Robert Stanek is the creator of CentralDrive.Com. His latest book, Server-Side JavaScript: The Definitive Guide, will be published in June. You can contact him at netdesigns@tvpress.com.
