How can I solve NullPointerException using ModelAndView object?

I found what made problem for 'nullPointerException'(Request processing failed; nested exception is 'java.lang.NullPointerException') as I used object 'ModelAndView' in the controller below.
Three kinds of variables can't get null below.
I know variable 'viewName' in the controller can't get value and object Map also can bring clear value as well. Furthermore, the variable 'idto' of object 'ItemDTO' has null instead of any value.
How can I fix existing codes suitable for the variables to get right value?
Below is the codes relevant to what I explain.
The code is controller below.
#Controller
#RequestMapping("booksale")
public class BookSaleController {
#Inject
private BookSaleService bService;
#RequestMapping(value="/itemDetail/{ino}")
public ModelAndView itemDetail(#PathVariable("ino")int ino, HttpServletRequest request,
HttpServletResponse response) {
String viewName = (String) request.getAttribute("viewName");
HttpSession session = request.getSession();
Map iMap = bService.itemDetail(ino);
ModelAndView mav = new ModelAndView(viewName);
mav.setViewName("/itemDetail/{ino}");
mav.addObject("iMap", iMap);
ItemDTO idto = (ItemDTO) iMap.get("idto");
appendItemQmenu(ino, idto, session);
return mav;
}
private void appendItemQmenu(int ino, ItemDTO idto, HttpSession session) {
// TODO Auto-generated method stub
boolean existing_presence = false;
List<ItemDTO> QuickItemList =
(List<ItemDTO>) session.getAttribute("QuickItemList");
if (QuickItemList != null) {
if (QuickItemList.size() < 3) {
for (int i = 0; i < QuickItemList.size(); i++) {
ItemDTO itemBean = QuickItemList.get(i);
String sIno = Integer.toString(ino);
if (sIno.equals(itemBean.getIno())) {
existing_presence = true;
return;
}
}
if (existing_presence== false) {
QuickItemList.add(idto);
}
}
}else {
QuickItemList = new ArrayList<ItemDTO>();
QuickItemList.add(idto);
}
session.setAttribute("QuickItemList", QuickItemList);
session.setAttribute("QuickItemListNum", QuickItemList.size());
}
The second code is about servlet-context.xml which is linked to MyBatis below.

From your question I understand that the value returned from the map in the line is null.
ItemDTO idto = (ItemDTO) iMap.get("idto");
You are seeing this error because the Map does not contain an entry corresponding to the key 'idto'. Please check if the values is supposed to be present in the map, if the entry is to be present then why the entry is missing.
Other thing that you can do in the same line
ItemDTO idto = (ItemDTO) iMap.getOrDefault("idto", "DefaultValue");
This will try to find the entry corresponding to the key 'idto', if the entry is absent then it returns a default value 'DefaultValue'.
You can check this for more details https://docs.oracle.com/javase/8/docs/api/java/util/Map.html#getOrDefault-java.lang.Object-V-

i have done this using jquery also, but displaying only first and last column values, but not the between columns. How can i display between columns and how can i edit row after displaying values using jquery. How to fetch that specific row values on to the form?

using equal you can pass index of tr and get object of particular tr. same way in td
see below example
$('#list tbody tr:eq(1) td:eq(0)').html();

Clear Cart button in Java

Hi I'm trying to make a "Clear Cart" button in my java code but i'm having difficulty.
I've been trying for a couple of hours but i can't get it to work
I think it has something to do mostly with the first part that has all the strings and variables.
Here's the code:

String id = request.getParameter("id");
if ( id != null ) {
String desc = request.getParameter("desc");
Float price = new Float(request.getParameter("price"));
cart.addItem(id, desc, price.floatValue(), 1);
}
%>

<action path="/Postaddd"
type="bseller.postadd.PostaddAction"
parameter="dispatch"
scope="request"
validate="true"
name="PostadddForm">
<forward name="posterror" path="ordererror.page"/>
<forward name="successPost" path="bseller.successPost.page"/>
</action> public ActionErrors validate(ActionMapping mapping, HttpServletRequest request)
{
Logger log= Logger.getLogger("BSELLER_APPLICATION");
log.info("validate method called");
ActionErrors errors = new ActionErrors();
log.info("Email Id: " + getEmailid());
if(!Validation.isValidEmailAddress(getEmailid()))
{
errors.add("emailid", new ActionMessage("prompt.email.error"));
}
if(!Validation.isPhoneNumberValid(getMobile()))
{
errors.add("mobile", new ActionMessage("prompt.contactno.error"));
}
if(!Validation.isNumeric(getPrice()))
{
errors.add("price", new ActionMessage("prompt.price.error"));

the validate method of actionform is always called when the form is submitted. you cannot manually call it unless you r reimplementing struts in ur own way. if u want a method to do the same work as the validate method, move the code of the validate method into another method and call it in the validate method. I do not completely understand what you are trying to do so please be more specific.

how to reload jsp page on every request?

i have a jsp page with jdbc connection and on first load it shows the data accurately but after that it shows empty tables i think 2nd time it loads from memory not from server
what is problem behind i don't know
ok here are the details
i have a servlet that maintains the session for a user that log in and then after creating the session the servlet redirect the user to a view page that is a jsp page and displays the existing records in DB
when the servlet redirects the page the jsp can show the records in but when i access this page from any other html page it is unable to display the records here is the code for jsp page to view.

It smells like threadsafety/scoping problem. You've declared the ResultSet and DBProcess as instance variable of the JSP using <%! %> scriptlet declarations, so it's been shared among all HTTP requests. I am not sure about the DBProcess, but this is certainly a bad idea for ResultSet (and also for Connection and Statement by the way). How the DBProcess is been used in the remnant of the code is also pretty scary, e.g. DBProcess.statement.executeQuery(). Is the Statement really a public field? I don't know how the class' internals look like, but yes, this smells too much like threadsafety/scoping problem.
Also, this 90's style writing of HTML and using scriptlets in JSP really don't suit a "Copyright 2010" application. Are you reading the right tutorials/books?

beside those issues pointed out by BalusC,
base on the described symptom "when the servlet redirects the page the jsp can show the records in but when i access this page from any other html page it is unable to display the records" and code "if(request.getAttribute("dbrec") != null) ".
My prime suspect for the issue's cause is the use of request.getAttribute("dbrec")
for those direct access from other html page, this value likely to be null. I suspect for redirect case, there may be some code that perform request.setAttribute("dbrec",....)
