from jsp to controller , value of all elements is null

Question

I m working with portlet and I use spring mvc and java. In the following code I get the value of all elements that are needed but at run time all values are null witch are taken by controller from jsp.

please help me as soon as possible.

In Controller:

@ActionMapping(params="myaction=OrderRegister")
void OrderRegister(ActionRequest request,ActionResponse response)
        throws IOException
{
     System.out.println("I love dear neda :* ");        

    TblSection sectionObj=orderServices.getSectionId(Long.parseLong(request.getParameter("searchSection")));
    Long subId=Long.parseLong(request.getParameter("searchSubsection"));       
    Long secId=sectionObj.getId();      
    TblSubsection SubsectionObj=orderServices.getSubsectionId(secId,subId);
    String TitleDivOrder=request.getParameter("InputTitleDivOrder").toString();
    String DescriptionDivOrder=request.getParameter("TextDescriptionDivOrder").toString();
    String DivMaxDeliveryDate=request.getParameter("InputMaxDeliveryDate").toString();
    String InputSuggestedPrice=request.getParameter("InputSuggestedPrice").toString();


    TblOrder ObjOrder=new TblOrder();
    ObjOrder.setTblSection(sectionObj);
    ObjOrder.setTblSubsection(SubsectionObj);
    ObjOrder.setTitle(TitleDivOrder);
    ObjOrder.setDescription(DescriptionDivOrder);
    ObjOrder.setMaxDateOfDeliveryCustomer(DivMaxDeliveryDate);
    ObjOrder.setCustomerPrice(Long.parseLong(InputSuggestedPrice));

    Long Ids=orderServices.registerOrder(ObjOrder);

    response.setRenderParameter("render", "RegisterOrder");
    }

in jsp:

<form:form  method="post" action="${OrderRegisterURL}" enctype="multipart/form-data">


<div id="OrderTypeDiv" class="OrderTypeDiv DivRow">
<div class="width100 Right"></div>
<div class="width125 Right">

Answer 1

As your form has enctype as mulitpart, you can get form parameters by uploadRequest.

Get upload request by code below and then get parameters from it.

UploadPortletRequest uploadRequest = PortalUtil.getUploadPortletRequest(request);
