java.lang.Objectcom.xigole.util.ClassFinder
public class ClassFinder
A simple utility to find a particular class name in a directory containing jar, war, and ear files. The application recursively decends into the directory looking for files that end in ".jar", ".war", and ".ear" (case insensitive which is not really the standard). Additionally, the program finds any normal files that end in .class also.
A sample command line might look like:
java -classpath lib/classfinder.jar -d some/directory/name -c SomeClassName
The command line arguments are:
Why did I write this? Because I find that when I'm looking for a particular class to compile with I never seem to know which jar file it is in. This utility simplifies that task. It is basically like a Unix "find" command piped to the "jar" command that would "grep" for the class name. Cross-platform issues made it easier to put into a small java application rather than have to install Cygwin on every Windows box I use. Copyright (C) 2004-2006 Scott Dunbar (scott@xigole.com)

Changes: November 07, 2006 1) Fixed a bug that prevented searching directories that ended with one of the Java archive extensions (.jar, .ear, .war, etc.). Thanks to Narasimhan Balasubramanian (narsibvl_2006@yahoo.com) for help with this. 2) Added the ability to find .class files too.
