Jar Ajar is a JAR-based self-extractor for zip files. It can package zipped files with descriptive images and text using a graphical interface. When recipients launch the resulting JAR, Jar Ajar guides users through the unzip process.


This release serves as a program launcher in addition to self-extracting and installing Java programs. The goal is for one downloadable file to serve as an installer, launcher, and program shortcut. After downloading a single file packaged by Jar Ajar, users can double-click the file to install and launch the program. When they double-click the file again, it automatically determines where the program was installed and launches it again, no matter where the original file has been moved.
