Did you use a wrong class that packaged in an irrelevant jar file? Are you trying to search a class from many jar files?

Java Class Finder is a free, small Java utility tool to search a given class from all jar files that in a selected directory (and subdirectories).

How does it work?

Simply specify the class name and a directory to search. Java Class Finder will find all jar files in the given directory (and subdirectories) that contain the given class.
