Import htmlb libraries

Hi Portal Experts!

I have one question, someone made an Login module it works. But I need to edit something, but as soon as i'm done and want to export it I get an error: The import com.sapportals.htmlb cannot be resolved etc

import com.sapportals.htmlb.*;

import com.sapportals.htmlb.enum.*;

import com.sapportals.htmlb.event.*;

import com.sapportals.htmlb.page.*;

import com.sapportals.portal.htmlb.page.*;

import com.sapportals.portal.prt.component.*;

So how can Import this one?! Because every .JAR that came with the PAR file is in the project...So i'm lost!
