Ok, if you are a nerd like me who codes in Java, you can relate to the following situation. You are compiling your code, or executing some software when BAM, an exception get’s thrown. Something is missing. You cannot dynamically locate a file. What the hell?!? Where is this file? The package isn’t one you’ve written. How the hell are you going to track it down?
Here’s the answer: Jarhoo. Jarhoo allows you to search an online database that maps classnames with jars, or jar files with packages, or jars with classnames. It’s an immense time saver. If you are that kind of nerd, this is definitely something you should have in your toolbelt.
