Pivotonic JavaJar 1.1: WYSIWYG Jar Tool
Java's jar utility is probably one of the most frequently used tools in the Java Software
Development Kit (SDK). JAR (short for Java ARchive) files are used to pack our
classes in an easily transportable format, as well as to store and deploy Web
applications and Enterprise JavaBeans (EJBs). JAR files (also Enterprise ARchives
(EAR) and Web ARchives (WAR)) are similar to zip files in that they contain
compressed files and folder structures. Generally, these files are created using
a command line interface, it is not too complex , but for those of us who find
ourselves in a Windows-oriented world it is nice to have visual tools. Enter
JavaJar. JavaJar is basically a WinZip for
Java JAR/WAR/EAR files. You can open existing archives or create new archives
from within this simple interface. JavaJar will even add options to your right-click
menu in Windows Explorer, so you can extract or create archives without having
to launch the application first.
JavaJar shows all of the files for the archive you are viewing in a Windows-like interface (there are even three skins to set how you want this interface to look). For each file, you will see the name, the file's original size, the compression ratio, the packed size, the last modified date (nice for checking versions of your applications) and the CRC (Cyclic Redundancy Check to prevent file corruption--part of the JAR spec). You can drag and drop these columns to set the order that makes the most sense to you, and as in Windows, you can sort by each of the columns and ascending and descending order. Double-clicking a file will allow you to view the contents of that file without extracting the entire archive. I both created archives and opened existing archives without problems.
JavaJar requires JDK 1.3 or 1.4 to run. Because it is a Java application itself, that is the only requirement. No other hardware/software recommendations are provided. JavaJar includes an Uninstall tool.
