JarCompare

Use this tool to compare jars that have minor differences (e.g. different builds of the same product) JarCompare understands that the archive contains Java classes, and drills down into the specific code differences between those classes. The tool decompiles the class files and displays differences in code lines. The output is XML, so you can format it any way you want. Version 1.1 features XML output; java -jar capability; removing the need to have an external decompiler.

Requirements:

Windows 95/98/Me/NT/2000/XP/2003 Server, Sun JDK 1.4.2
