displaying a bean

displaying a bean

Hello everyone.  I have a small struts problem.

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?


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 ****-->

RE: displaying a bean

remove the <bean:define...

RE: displaying a bean

Well, it's not strange that this happens... In this line of code in your action


request.setAttribute("courses", courses);
you're putting the object in the request, not the session.
