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);
System.out.println(courses.getTrainer().getTrainerName());
System.out.println(courses.getCourseName());
request.setAttribute("courses", courses);
return mapping.findForward("dispres");
}
}
<--**** dispres.jsp after this point ****-->

You are saving the bean in request scope but looking for it in session
scope. Change these to match. Request scope is preferred unless there is a
compelling reason to use session scope.
