Question

Hai anyone,. I' a newbie to struts and want to learn more. I download the example code, and run it. Hey, it work. But when I try to create it by myself by following the tutorial, I got stuck with my all java file when i want to try to compile it with eclipse.It say:
The import org.apache.struts.action.ActionError cannot be resolved
What' wrong?
this is one of the example code, i bolded the error line:
package dummies.struts.music;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.validator.DynaValidatorForm;
* @author Mike Robinson
public class LoginAction extends Action
     * Handles request from user
     * @param mapping
     * @param form
     * @param request
     * @param response
     * @throws Exception
     public ActionForward execute(      ActionMapping mapping,
                                             ActionForm form,
                                             HttpServletRequest request,
                                             HttpServletResponse response)
                                             throws Exception
          // did the user click the Join button?
          Boolean bCancel = (Boolean)request.getAttribute("org.apache.struts.action.CANCEL");
          if(bCancel != null)
               if(bCancel.booleanValue())
                    return (mapping.findForward("join"));
          // create a new LoginBean passing the datasource
          LoginBean lb = new LoginBean(getDataSource(request, "musiccollection"));
          // check to see if this user/password combination are valid
          // will return a non-null UserDTO if valid
          UserDTO user = lb.validateUser((String)((DynaValidatorForm)form).get("email"),
                                             (String)((DynaValidatorForm)form).get("password"));
          if(user != null)
               // save UserDTO in session
               request.getSession().setAttribute("user",user);
               return (mapping.findForward("success"));
          else     // username/password not validated
               // create ActionError and save in the request
               ActionErrors errors = new ActionErrors();
               ActionError error = new ActionError("error.login.invalid");
               errors.add("login",error);
               saveErrors(request,errors);
               return (mapping.findForward("failure"));
