JarBuilder allows programmers to easily create jar files. It is written in Java, providing a nice Swing GUI. Although it isn't programmed as a classic wizard, Java programmers are able to build their own jar files with JarBuilder in three steps. First, you selected the files you want to include in the jar file, then you load or write your manifest file (JarBuilder can do an automatic search for main classes for you and add the correct statement to the manifest file). Finally, you select the compression level of the jar file, and JarBuilder creates the file for you.
