The Jar Ajar™ tool is a JAR-based self-extractor for ZIP files, where one file serves as an installer, launcher, and program shortcut.

If you're looking for a small community in which to get involved, you've come to the right place! This project started out as a homegrown helper for the Text Trix editor and continues to focus on simplifying distribution of Java-based software.

Which Java version do I need? Java 6 is available for free for Windows, Linux, MacOS X, and OpenSolaris platforms. MacOS X, Fedora, and Ubuntu all come standard now with compatible Java software. If your computer does not have Java software, learn how to install it. Jar Ajar sofware may also run on Java 1.4 or 5.0 software.
