displaying a bean
displaying a bean
(OP)
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);
System.out.println(courses.getTrainer().getTrainerName());
System.out.println(courses.getCourseName());
request.setAttribute("courses", courses);
return mapping.findForward("dispres");
}
}
