How to use 3rd party classes in Eclipse

[hahncj55408]

Hello,
I've been banging my head against the wall trying to figure out how to do this.
I've written a GUI program for my software engineering class, I would like to use the JFreeChart program within it. I have downloaded the software, but cannot figure out how or where to save it so I can access it from my eclipse project (With the exception of manually copying and pasting all of the classes into the package I am using).
I'm sure the process involves saving the files somewhere and using an import command.

I have the same question for just about every general class I have written. If I have a class that is a useful tool that I'd like to use in future programs, how do I save it in a general area that I can re-use it for all my future projects?

If you have suggested reading material regarding how the professionals organize their eclipse workspace, that'd be great too.

Thanks in advance for your help.

Chris

This is Java forum not an Eclipse helpdesk. You would have better luck asking in an Eclipse forum. But you should go into the properties of your project and there should be an option to add a library.

Open the Project Explorer (if it's not already open) by selecting Window > Show View > Project Explorer. Right-click your project and select Properties. Select Java Build Path on the left, and then select the Libraries tab on the right. Click the Add External JARs button. Select the jar you want to add to the project.
