I downloaded this library for low level Java keyboard hooks:

It works great, but I want to attach the source to it. The source is included as .java files, but when I go to attach them to the library in eclipse it only wants a jar or zip file. I tried zipping the .java files but it didn't work. I've never attached a source before, can someone help me out?
