I'm using netbeans 6.9.1 to build up a task using frameworks Hibernate 3.2.5 and JavaServer Faces, i most likely adopted this tutorial

http://netbeans.org/kb/docs/web/hibernate-webapp.html

Within this tutorial it uses GlassFish 3 to create the project that we did too and delay pills work fine. However when i used it to my server on apache tomcat 7, it gives this error "Class DBws.DBws isn't a Servlet"

I transformed the server from glassfish to apache in netbeans also it began giving error in file about this location

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;

having a red-colored line under javax, how to proceed now, thanks

Add jsf libraries inside your WEB-INF/lib folder, libraries are available here.

Glassfish automatically has individuals libraries however i guess tom-cat does not.
