Displaying a bean in Struts.

Hello everyone. I have a small struts problem. I looked for a struts
newsgroup, but there doesn't seem to be one, so I'll give it a shot here.

I have the following Action class with an attribute called 'courses'. I
then get forwarded to a .JSP page (called "dispres.jsp") so that I can
display the bean. The problem is that I keep getting the message that
it: "Cannot find bean courses in scope session". Does anyone know how I
can fix this?

(I lost the formatting on my .jsp file, so it appears to be left
justified. Sorry.)

public class SearchAction extends Action {

     public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {

         String searchString = ((SearchForm)form).getQuerystring();

         CourseDto courses = new CourseDto(searchString);

         BusinessLayer businessLayer = new BusinessLayerImpl();
         courses = businessLayer.findCourse(searchString);


         request.setAttribute("courses", courses);

         return mapping.findForward("dispres");

<--**** dispres.jsp after this point ****-->
