RE:[OT] Using JSTL to check for empty attribute
That does not work either.
I have an action that sets the attribute as follows:
Collection corrections = new Vector();
corrections.add(new Correction("cor1");
corrections.add(new Correction("cor2");
request.getSession().setAttribute("corrections", corrections);
Then it forwards the user to the JSP page as follows:
return mapping.findForward("corrections_overview");
I need to check if the attribute corrections has been set in this JSP
page.
That does not work...
Any other suggestions?
Thanks,
