display the content of an arraylist (controller) to jsp

Question

edit

I have a method returns an ArrayList which display products. I had created a controller

final String inputFileName = "Onto.owl";
String categorie = "Mode";
String nom = "HasName";
String description= "HasDescription";

@RequestMapping(method = RequestMethod.GET)
public ModelAndView handleRequest(HttpServletRequest arg0,
        HttpServletResponse arg1) throws Exception {
    ModelAndView modelAndView = new ModelAndView("index");
    modelAndView.addObject("pList", GetAllFonction.displayProducts(inputFileName, categorie));

    return modelAndView;
}

then I iterate using c:foreach on the the ArrayList(pList)

<c:forEach var="value" items="${pList}">
  <tr>
  <td> <c:out value="${value}"/></td>
   </tr>
</c:forEach>

but the table is empty.

Answer 1

please check GetAllFonction.displayProducts(inputFileName, categorie) method is returning any values or it is empty.

OR

instead of this line

modelAndView.addObject("pList", GetAllFonction.displayProducts(inputFileName, categorie));

You can add below code to cross check it

List<String> **list**=new ArrayList<String>();
list.add("vishal");
list.add("biradar");

modelAndView.addObject("pList",**list**);
