Error loading a class into flash

Hi!

I download XIFF API, extract it and copy the ''org'' directory
into Flash 8: ''C:\Program Files\Macromedia\Flash
8\en\Configuration''.



I test a movie user XIFF API:

EX:

import org.jivesoftware.xiff.core.XMPPConnection;

var connection:XMPPConnection = new XMPPConnection()



And it gives me the error:

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 12: The
class or interface 'org.jivesoftware.xiff.core.XMPPConnection'
could not be loaded.

var connection:XMPPConnection = new XMPPConnection();



I hope anyone has ideas!
