using external library

I want to use external java library (
How can I include it in the project?
I created lib folder, put there jar file, than I have added build path.
In class I have imported net.htmlparser.jericho.*;
But I'm getting an error:

SEVERE: Servlet.service() for servlet WebTools threw exception
java.lang.ClassNotFoundException: net.htmlparser.jericho.Segment

Did I forget about something?

i guess this is because the project needs to be a Dynamic Web Project and the library files needs to be in WEB-INF/lib folder
Yes, they should get deployed there if they're in the build path correctly
