Using an EAR file to create new project in JDeveloper

I'm not even sure if I worded the question correctly. I've tried googling, but can't find anything relevant.

Basically I need to create a working project folder in JDeveloper from an ear file. The ear file is all I have, and I need to be able to modify code.

Any help would be greatly appreciated.

JDeveloper has an option to create a new application from EAR file. Right click on Applications on the Application Navigator, Select New..., General -> Applications -> Application from EAR file.
