Find a class in a jar

Two of the most useful tools I have ever used are the jarminator and the jar browser. These tools are simple; you give them a location, they load up all the jar files and then you search for a given class. If the class exists in any of the loaded jar files they will tell you which one it is in. Extremelly useful when you are working with new APIs.

My personal favourite is Jarminator, since it’s easier to use. You just have to input the class name and it looks in all jar files (whether with jar browser you have to input the class name plus the .class extension). Jar browser is also not bad at all but the project seems abandoned (it has not been updated since 2004).
