problem barcode

Hi, I'm trying to use the barcode, I follow the instructions in the repository but when I compile the explanation gives me errors:

[WARNING] Extension found in C:\Program Files (x86)\Research In Motion\BlackBerry WebWorks Packager\ext\webworks.media.barcode\library.xml does not have id defined. [WARNING] , , or tag missing. Extension found in C:\Program Files (x86)\Research In Motion\BlackBerry WebWorks Packager\ext\webworks.media.barcode\library.xml will be ignored [ERROR] Feature cannot be found in any extension(webworks.media.barcode).

Can you help?

thanks
