Eclipse is an open-source Integrated Development Environment (IDE) supported by IBM. Eclipse is a popular script creator for Java application development (Java SE and Java EE) and Android apps.

I've created a new project in Eclipse, put the jar files in that project, and added that to the build path.

Huh, yes.<BR><BR>If your project is in c foo\, I suggest you make a c foo\src folder and put *your* .java files there. Tell Eclipse that src is your source folder (not your project folder).
