I’ve been wanting one of these for ages! You know the name of the class, but not which jar it lives it (I’ve always had problems finding the jar containing the JNDI naming provider for Websphere 4/5 - especially with about 6 different IBM JDKs on my PC!)
This Jar Class Finder plugin is just what I was looking for! Search in a given directory (and subdirectories) for Jars/Zips/properties files containing the given Class. Integrates with a nice little toolbar button, and a nice tabular view of the matching files.
Sensational piece of work. This is going to be a standard part of my toolkit forever! Great find.
