eclipse & usebean

Hi,
I'm developing a small webapplication and some days ago i decide to try
eclipse-wtp 2.0 instead of normal editor.
When I compiled the source I recived this error message:

"org.fame cannot be resolved to a type"

This is a a part of the source:

<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>

<jsp:useBean scope="session" id="user" type="org.fame.users.User" />

I looked around internet but i didn't find solutions.
Any help will be really appreciated

Thanks
