How to retrieve selected item details (Product Id, Quantity) in Action clas

Question

Hi
I want to retrieve the selected item details (Product Id, Quantity) in my custom action class .I am calling custom action event after u2018add to cartu2019 button clicked.  I basically need these details to pass to custom BAPI. I can able to retrieve User Name and itemkey successfully.  I Tried to retrieve the product , productID using WebCatItem but I was getting run time error and when I debug the code I can see webCatItem coming  as null. Below is my code. 
public class Z_AddToBasketAction extends BaseAction {
     /* (non-Javadoc)
@see com.sap.isa.core.BaseAction#doPerform(org.apache.struts.action.ActionMapping, org.apache.struts.action.ActionForm, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
     public ActionForward doPerform(
          ActionMapping mapping,
          ActionForm form,
          HttpServletRequest request,
          HttpServletResponse response)
          throws IOException, ServletException {
          //Cache.Access access = null;
          Map returnValues = null;
          UserSessionData userSessionData =
               UserSessionData.getUserSessionData(request.getSession());
               BusinessObjectManager bom =
                         (BusinessObjectManager) userSessionData.
                         getBOM(BusinessObjectManager.ISACORE_BOM);
     String selectedPartnerID = bom.getUser().getUserId();
     String strItemkey=request.getParameter("itemkey");
     WebCatItem webCatItem =     (WebCatItem) request.getAttribute(
                         com.sap.isa.catalog.actions.ActionConstants.RA_WEBCATITEM);
     //If you are looking at Product attributes.
      String att =  webCatItem.getProduct()", "webCatItem.getProductID();
     ZBOM mybom = (ZBOM) userSessionData.getBOM(ZBOM.ZCUSTOM_BOM);
     return mapping.findForward("success");
Please help
Thanks

Hi Arvinda,
From which page you are trying to add products in cart? Are you selecting only 1 item at a time and then click on Add to cart button or you select more then 1 items to add into cart.
You can ceate hidden input filed and set their value through java script when you select any item. If more then 1 items then you can create an arry and set in the request parameter and then retrieve it in your custome class.
