Make sure you run your query in Toad or SQL before additing it to the VO object.
Usually null pointer exception caused by a null value from the query or the query is wrong. You cant just modify the VO query blindly, if you are adding conditions then its OK, but if you are adding new fields you need to extend the VO object.,

I can't figure out why I'm getting a Null Pointer Exception
I'm writing a program that calls Bingo numbers. I got that part of the program to work but when I started adding Swing I kept getting a Null Pointer Exception and I don't know how to fix it. The Exception happens on line 15 of class Panel (g = image.getGraphics();). Here is the code for my classes. I'm still not finished with the program and I can't finish it until I know that this issue is resolved.

Not sure, but it may be that you need to call init() after this.setVisible(true). -

Can anyone help. when i run the program i get a null pointer exception
can you tell me why, and possibly tell me how i can search through the array of customers searching for an id number
am i doing it a way that will work (not the best way) but just so it works
thanks in advance
D_HNevertheless, when you get to the loop where your exception occurs, you may have created any number of customers, but probably not 100.
The loop tries to go through all 100 spaces in the array, and as soon as it gets to a space you haven't assigned a Customer too, you'll get the exception.
Either make sure the loop doesn't go higher than you cutomercounter - 1 (to compensate for 0-based index of array), or check if the customer[i] == null before you try to call a method on it.
Does that make sense?

Null reference exception using Microsoft.Unity on DisposeOfChildContainer()
I am working on mvc application which also has webapi. Application is throwing System.NullReference Exception in production.

Is the exception a bug in unity or something is missed in this implementation. I have been searching the issue since a week but could not get anything.Hello,

(JSF) newbie null reference exception
error:

I am a Java web development scrub / newbie. I am assuming this is because i did not have an instance of the Login class. However, tutorials that i have seen have done similar tasks without creating an instance (and they are not static classes) so i am confused. Please help me understand why i am getting this error and how to make this simple web application work. Thanks in advance.

}you are apparently also a Java "newbie", otherwise you would have posted/searched for your best friend in the world: the exception stacktrace. I hope you realize that learning Java web development is a frustrating and confusing thing to do if you don't know proper core Java.
Lets use some good old fashioned reasoning. See this code:
if(username.equals("ianmcdavid") && password.equals("cole")) {
return "success";
}When the class is created, username and password will be null. Might that perhaps be the cause of the NullPointerException?
Try this in stead:
if("ianmcdavid".equals(username) && "cole".equals(password)) {
return "success";
}That won't ever cause an NPE while still providing the same functionality. -

I am trying to test some of my AS classes in flexunit. Some of the methods reference the stage from components that are passed to it. When I set up the flexunit testing application I use the following code:
core = new FlexUnitCore();
core.visualDisplayRoot = this;
core.addListener( new UIListener( uiListener ));
However, I still get a null reference exception whenever the stage is referenced. I was wonding if anyone knew what is going on or what I am doing wrong.
Thanks!Okay, a few things.
If you are using Flex, you don't need to set the visualDisplayRoot. That is for ActionScript only projects.
Second, display objects in Flash don't have access to the stage until they are on the display list. So, saying
new Image() won't add that item to the display list.
I am not sure what Control.initApp() does, but in one of your unit tests, they way you get something on the display list is to use the UIImpersonator:
UIImpersonator.addChild( someImage );
After that someImage would have access to the stage. However, bigger problem. Unit tests are about isolation and if you components need to get out to the stage or if Control.initApp() somehow adds the item directly to the display list you are going to continue to have different issues as you won't be able to keep things in isolation to test.
Hope that clarifies a little bit,

Really frustrating Null Pointer Exception
Hi I had the day off and was bored so I decided to start work on a poker game. Today I just started making a deck of cards and drawing a random card from it. However it isn't working as I get a very annoying null pointer exception which I don't understand. Anyway I will post my code:
public class DeckOfCards
public static void main(String args[])
Deck daDeck = new Deck();
Card[] drawnCards = new Card[10];
for (int i=0; i < 10; ++i)
drawnCards[i] = daDeck.DrawCard();
System.out.println(drawnCards.getTitle());
import java.util.*;
public class Deck
Suit Hearts;
Suit Diamonds;
Suit Spades;
Suit Clubs;
public void Deck()
Hearts = new Suit("Hearts");
Diamonds = new Suit("Diamonds");
Spades = new Suit("Spades");
Clubs = new Suit("Clubs");
public Card DrawCard()
System.out.println("Drawing card...");
Random generator = new Random();
Card card = null;
System.out.println("Card variable inited");
while (card == null)
System.out.println("Bleep");
switch (generator.nextInt(4))
case 0:
System.out.println("0");
return Hearts.getAvailableCard();
case 1:
System.out.println("1");
return Diamonds.getAvailableCard();
case 2:
System.out.println("2");
return Spades.getAvailableCard();
case 3:
System.out.println("3");
return Clubs.getAvailableCard();
default:
System.out.println("none");
System.out.println("Exited while loop");
return card;
import java.util.*;
public class Suit
Card[] cards = new Card[13];
public Suit(String suit_)
cards[0] = new Card("Two", suit_);
cards[1] = new Card("Three", suit_);
cards[2] = new Card("Four", suit_);
cards[3] = new Card("Five", suit_);
cards[4] = new Card("Six", suit_);
cards[5] = new Card("Seven", suit_);
cards[6] = new Card("Eight", suit_);
cards[7] = new Card("Nine", suit_);
cards[8] = new Card("Ten", suit_);
cards[9] = new Card("Jack", suit_);
cards[10] = new Card("Queen", suit_);
cards[11] = new Card("King", suit_);
cards[12] = new Card("Ace", suit_);
public Card getAvailableCard()
System.out.println("Getting an available card...");
Random generator = new Random();
Card card = new Card();
int randomNo = generator.nextInt(13);
System.out.println(randomNo);
if (cards[randomNo].isAvailable())
return cards[randomNo];
return card;
public class Card
String strValue;
String suitName;
int value;
int suit;
boolean available = true;
public Card()
strValue = "Out";
suitName = "cards";
public Card(String strValue_, String suitName_)
strValue = strValue_;
suitName = suitName_;
public String getTitle()
String title = strValue + " of " + suitName;
return title;
public void setAvailable(boolean available_)
available = available_;
public boolean isAvailable()
return available;
What the program is meant to do is create a deck of cards, then pick ten cards, randomly picking a suit and card in that suit. If the card has already been drawn ( not available ) then the DrawCard() method should repick a suit and card and try again. The program may be doing something differently to what I have said and may be a bit messy just because I have messed around with things trying to understand why I am getting the exception. This is the exception:
Exception in thread "main" java.lang.NullPointerException
at Deck.DrawCard(Deck.java:34)
at DeckOfCards.main(DeckOfCards.java:13)
The program doesn't even make it to the first line of the getAvailableCard() method in the Suit Class.
So all I am asking is can anyone see why I am getting the null pointer exception and what action could I take to fix it. Thankyou to anyone who has read this.Figure out what's null.
Print out cards and then cards[randomNo].
If those aren't null, then you need to look more closely at the erorr message and put in print statements to find out what is.
Whatever turns out to be null, you'll need to trace back and figure out why.
If it's the array, and the array is a member variable, then you need to know that reference member variables are initilaized to null.
If the array isn't null (because you did cards = new Card[something]) but cards[randomNo] is null, then it's because you didn't do this: for (int ix = 0; ix < cards.length; ix++) {
cards[ix] = new Card(...);
} -
Java Null Pointer Exception - with arraycopy method.
Hi all,
I have been trying to fix this for a while now, but I think I've been staring at the screen for too long to fix it!
Basically I am trying to 'crossover' some arrays (evolutionary technique) but I keep getting a null pointer exception.
Here is my customised class: class ChromosomeDetails {
double[] chromosomePrices;
int[] chromosomePoints;
int[] chromosomePlayerIDs;
int chromosomeFitness;
ChromosomeDetails(double[] chromosomePrices, int[] chromosomePoints, int[] chromosomePlayerIDs, int chromosomeFitness) {
this.chromosomePrices = chromosomePrices;
this.chromosomePoints = chromosomePoints;
this.chromosomePlayerIDs = chromosomePlayerIDs;
this.chromosomeFitness = chromosomeFitness;
public ChromosomeDetails () {
chromosomePrices = null;
chromosomePoints = null;
chromosomePlayerIDs = null;
chromosomeFitness = 0;
public double[] getPrices() {
return chromosomePrices;
public int[] getPoints() {
return chromosomePoints;
public int[] getPlayerIDs() {
return chromosomePlayerIDs;
public int getFitness() {
return chromosomeFitness;
} In my main method I create 2 instances of this class like so:ChromosomeDetails parentChromosomeADetails = new ChromosomeDetails();
ChromosomeDetails parentChromosomeBDetails = new ChromosomeDetails();...and 2 other instances that are left empty:ChromosomeDetails childChromosomeCDetails = new ChromosomeDetails();
ChromosomeDetails childChromosomeDDetails = new ChromosomeDetails(); I then try to 'crossover' the values in the arrays like so: int randomCrossoverPoint = new Random().nextInt(parentChromosomeADetails.chromosomePoints.length-1);
System.arraycopy(parentChromosomeADetails.chromosomePrices, 0, childChromosomeCDetails.chromosomePrices, 0, randomCrossoverPoint);
System.arraycopy(parentChromosomeBDetails.chromosomePrices, randomCrossoverPoint, childChromosomeCDetails.chromosomePrices, randomCrossoverPoint, (childChromosomeCDetails.chromosomePrices.length-randomCrossoverPoint));
System.arraycopy(parentChromosomeADetails.chromosomePoints, 0, childChromosomeCDetails.chromosomePoints, 0, randomCrossoverPoint);
System.arraycopy(parentChromosomeBDetails.chromosomePoints, randomCrossoverPoint, childChromosomeCDetails.chromosomePoints, randomCrossoverPoint, (childChromosomeCDetails.chromosomePoints.length-randomCrossoverPoint));
System.arraycopy(parentChromosomeADetails.chromosomePlayerIDs, 0, childChromosomeCDetails.chromosomePlayerIDs, 0, randomCrossoverPoint);
System.arraycopy(parentChromosomeBDetails.chromosomePlayerIDs, randomCrossoverPoint, childChromosomeCDetails.chromosomePlayerIDs, randomCrossoverPoint, (childChromosomeCDetails.chromosomePlayerIDs.length-randomCrossoverPoint));
However it gives me this error, relating to the first arraycopy method: Exception in thread "main" java.lang.NullPointerException
at java.lang.System.arraycopy(Native Method)Please note that in this program, parentChromosomeADetails and parentChromosomeBDetails already hold data when I try to use the arraycopy method, whereas the childChromosomeCDetails and childChromosomeDDetails objects are empty, waiting for the data from the arraycopy methods. Any help would be immensely appreciated.it was learning very well yesterday, but that was before I introduced my customised class. I need my class as I need to be able to keep hold of all of the data, rather than just the chromosome points, so that I can see the exact strategy that the algorithm uses.
It is indeed the child chromosome that is null, and I suppose that it because I had to initialise the int[] chromosomePoints, double[] chromosomePrices and int[] chromosomePlayerIDs as null. What is the best solution to this? using loops to initialise all values in the arrays as 0 before the arraycopy?! -
Null Pointer Exception While calling function
Excuse my ignorance, as I just started programming in Java, but while trying to give control to a function other than main(), I get a null pointer exception. I don't think that I'm calling the function properly, because I feel that I may need to start a new thread, but I don't know how to go about it. Please help.
Here's the code(not the whole thing, just the important part):
public static void main(){
//some stuff to run
mainplace();
public static void mainplace(){
//stuff is in here
}firstly the first main . Is this a typo
shouldn't it be
public static void main(String [] args) {
mainplace();
I say this cuz when u complile a class and try running it the first thing that gets called is the main method with String[] as the arguments.
public static void mainplace() {
// some thing here
}it would be better if u post the code cuz, frankly nothing can be understood from ur previous post.
there could be many reasons for the NullPointerException.

Returning vector and null pointer exception
Hi, I'm writing a mailing program which so far is working fine, but I have now run into a problem which is completely throwing me. My mailer needs to be able to load multiple attachments - and also to be able to deal with an HTML text which contains multiple images. In each case, what I'm trying to do is to put the attachments and the images into separate vectors and process them through an iterator. The logic, at least, I hope is correct.
I can get my code to compile but it keeps throwing a null pointer exception a runtime. Somehow, I just can't get it to pass the vector from one part of the code to another.
Can anyone help me? I've tried various things, none of which seem to work. My code, as it stands, is posted in a skeletal form below.
Thanks for any ideas:
public class MailSender
// declare various variables, including:
Vector embeddedImages;
String HTMLString;
public MailSender()
setup();
private void setup()
//this part of the program sets up the various parts of the mail (to, from, body etc)
HTMLString = "blah blah blah"; //sample HTMLString
Vector embeddedImages = null; //is this correct?
if (HTMLString.length() > 0)
processHTMLString(HTMLString);
private String procesHTMLString(String htmlText)
Vector embeddedImages = new Vector(); // I construct my vector here, is this correct?
//Here I process the HTML string to extract the images
//get the file path of the image and pass it to the vector
addToVector(imageFile);
return HTMLString;
public Vector addToVector(String imageFile)
embeddedImages.add(imageFile);
return embeddedImages;
private void send()
//this part does the sending of the mail
//at some part in this method I need to get at the contents of the vector:
//but this part isn't working, I keep getting a null pointer exception
Iterator singleImage = embeddedImages.iterator();
while (singleImage.hasNext())
public static void main(String[] args)
MailSender ms = new MailSender();
ms.send();
System.out.println("MailSender is done ");
}>>>>while they don't have a clue on how the language and/or programming in general works.
Thank you, salpeter, for your esteemed estimation of my programming competence.
>>>What I'm wondering is: how come people always start building applications... blah blah
The reason being, is that it happens to be my job.
OK, I'm perhaps slower than most and there are things I don't yet understand but I get paid probably about a tenth of what you do (and maybe even less). I regard it as a kind of apprenticeship which, after a past life having spent twenty years packing crates in a warehouse, is worth the sacrifice. Six months ago I'd never written a line of code in my life and everything I've learned since has been from books, the good people in these forums, and a lot of patient trial and error. It's hard work, but I'll get there.
I say this, only as encouragement to anyone else who is trying to learn java and hasn't had the benefit of IT training at school and a four year computing course at university paid for by the parents, and for whom the prohibitive cost (in both time and money) of most java courses would never allow them to get on this ladder.
Excuse my somewhat acerbic posting, but comments such as yours tend to provoke...
Thank you EverNewJoy for explaining this to me. I haven't had time yet to try it out, but at least the concept now is clear to me. -
Af:tree Null Pointer Exception using af:switcher
Hi,
I've implemented a Tree (based on 3 linked SQL Query View Objects). The linked View Objects run ok in the Application Module tester...
I wanted to customize the different levels of the tree so implemented a Switcher component on the Tree as follows (note I've limited the Tree to 2 levels):
<af:tree value="#{bindings.listToDoAppsVO1.treeModel}" summary="ToDo List Tree" var="node"
id="pt_t8" contentDelivery="lazy"
initiallyExpanded="true"
styleClass="AFStretchWidth" inlineStyle="height:inherit;">
<f:facet name="nodeStamp">
<af:switcher facetName="#{node.hierType.structureDefName}" id="todo_switcher">
<!-- render the Application Node -->
<f:facet name="app_model.listToDoAppsVO">
<!-- display the Application as the node name -->
<af:outputText value="#{node.Appname}" id="ot_app">
</af:outputText>
</f:facet>
<f:facet name="app_model.listToDoTypesVO">
<!-- Create the node definition for the Report Type -->
<af:commandImageLink id="pt_ot16"
text="#{node.Viewtype}"
icon="/pics/folder-icon.png"
action="callRouter"
actionListener="#{backingBeanScope.cognition3coltempBacking.toDoViewGoActionListener}"
/>
</f:facet>
</af:switcher>
</f:facet>
</af:tree>However, when the page is run the Tree displays correctly initially, but as soon as a link is pressed I get a Null Pointer exception with the following Stack Trace info (top 30 or so lines):

Thanks.Hi Frank,
Thanks for your reply. The Partial Submit worked up to a point - the expected navigation to the new view now works when the link is initially pressed. However, if the link is tried again the Null Pointer Exception occurs again.
By the way, the Tree is on a Page Template, where there is another Tree that utilises an af:switcher - and the command link from this tree now fails with the same NPE error. I notice there are warnings for both trees in the Page Template View such that 'Reference "node.hierType" not found'. Not sure how relevant this is given that the Trees both display correctly initially.
The Stack Trace is as follows (can't post the whole thing as it exceeds the 30000 char limit):
<UIXInclude> <_warnUnpoppedContextChanges> ADF_FACES-10021:During the processing of the include component, the context change found did not match the current component.
