problem with org.apache.jasper.JasperException: java.lang.NullPointerException

I could not find my mistake. Here is my code. Thanks in advance.

    <body>
<%

        String pack_id = request.getParameter("pack_id");
        String pack_name = request.getParameter("pack_name");
        String pack_day = request.getParameter("pack_day");
        String pack_price = request.getParameter("pack_price");
        String pack_max = request.getParameter("pack_max");
                String pack_act = request.getParameter("pack_act");
                //String pack_meal = request.getParameter("pack_meal");

                String meal="";
                String pack_meal[]=request.getParameterValues("pack_meal");
                for(int i=0;i<pack_meal.length;i++){
                    meal+= pack_meal[i]+" ";
                }
                String act="";
                String act_name[]=request.getParameterValues("act_name");
                for(int i=0;i<act_name.length;i++){
                    act+= act_name[i]+" ";
                }


        %>



 <% 

   String addPackage = "INSERT INTO ACTIVITY VALUES('"+pack_id+"','"+pack_name+"','"+pack_day+"','"+meal+"','"+act+"','"+pack_price+"','"+pack_max+"')";

        Statement statement = conn.createStatement();



        statement.executeUpdate(addPackage);



        %>
        <script language="javascript">
             alert("Successfully Inserted!");

             //response.sendRedirect("Student/homeStudent.jsp");
             window.location.href = "adminCreatePackage.jsp";
        </script>

   }
   }

I had also faced the same problem. I got the solution to solve this problem.

Root of this problem is: I had added the servlet-api.jar and jsp-api.jar in my application lib directory. If Apache-tomcat is used to run application then its not necessary to add this jar files in our lib directory.

Goto build Path -> add external jars from tomcat-lib dir. Instead of adding(copying) it in lib dir of application.

This will resolve the problem.
