package com.inv.action;

import javax.servlet.http.*;
import com.inv.actionform.ItemActionForm;
import com.inv.logic.ItemLogic;

public class ItemAction extends Action {

    /**@todo: complete the business logic here, this is just a skeleton.*/

        ItemActionForm form = (ItemActionForm) actionForm;
         System.out.println("=========================================");
        ItemLogic logic = new ItemLogic();
         System.out.println("=========================================");
        logic.setForm(form);
         System.out.println("=========================================");
        if(form.getOperation().equals("delete"))
        {

          form.setOperation("display");
        }
        if(form.getOperation().equals("save"))
