Cannot access instance method

I want to get a Vector obj result (inside my JSP page) by accessing an instance method of a class I've put in a package and I keep getting a java.lang.NullPointerException.
The skeleton of the class in the package is:
MyClass.java
package myPackage;
import java.util.*;
public class myClass {
String string_A;
String string_B;
public myClass(String s_A, String s_B) {
string_A = s_A;
string_B = s_B;
public Vector getVector() {
Vector myVector = new Vector();
myVector.add(string_A);
myVector.add(string_B);
return myVector;
... and the JSP that goes the wrong way is:
Page.jsp
<%@ page contentType="text/html;charset=WINDOWS-1253"%>
<%-- The following String comes from HTTP POST--%>
<% String request_A = request.getParameter("foo"); %>
<% String request_B = request.getParameter("bar"); %>
<html><body><p>
<% try {
myPackage.myClass myClassObj =
new myPackage.myClass(request_A, request_B);
try {
Vector v = myClassObj.getVector();
} catch (Exception e) {
out.println("Cannot access Obj Method: " + e); (*)
} catch (Exception e) {
out.println("Cannot Initialize Obj: " + e);
%>
</p></body></html>
When I run the above JSP page I get:
"Cannot access obj method : java.lang.NullPointerException" (*)
Why can't I access this method?!?

it doesn't matter whether they are in same package or different packages as long as we can resolve the scope properly . Here I assum e that Prog1.java is top level container which is holding the instacnes of prog2 and prog3 . now some action of prog2 should invoke some method on prog3 . Here prog2 doesn't know the existence of prog3 as two are independent and only thing thats linking both of them is Prog1.So its staright forward that any such communication should happen through Prog1. While instantiating Porg2 set the reference of Prog1 in prog2 . soemthing like Prog2 p2 = new Prog2(); p.setTop(this);
Ofcourse this involves code change in Porg2 . then from the listenere you can simply call method m3 in prog3 like p2.getTop().p3.m3(); hope this helps..

  • Access instance method of a class inside instance method of another class

    Hi Friends
    I have to use one c1->m1.
    c1 is a public instantiation and m1 is a public Instance Method.
    I called this m1 method by creating c1 object for class c1.
    But problem is inise M1 method,i have a statement
    CALL METHOD mo_central_person->if_hrbas_pd_object~read_infty.
    here mo_central_person is of type some other class c2.
    As without creating the object,i didn't use the above interface method.
    Can please suggst me how to handle this.

  • This static method cannot hide the instance method from...

    What means the error message "This static method cannot hide the instance method from Referee"?
    Referee.java is a interface. I implemented it in the class RefereeMyName.java and made a method in that class to be static. Thats why I received that error message.
    But can't I use static methods when I have implemented a interface in that class? I want to have a Player.java class which I want to access RefereeMyName.getTarget(). I cannot use a instance instead because I wouldn't receive a valid return value then (RefereeMyName is the client class).
    What is the solution?

    Hi,
    Well i do not think that you can do that b'cos that way you are not giving the same signature for the method as that exists in the interface. I do not know how other way it can be done but if something urgent for you then you can remove that method from that interface and only define in the class.

  • Error #1009: Cannot access a property or method

    Here's the context of the problem, in which I will try to include as much information as possible while keeping the explanation brief.
    I am trying to make a portfolio website (architectural design + concept art).  Flash / programing are not my focus and this is my first go at learning the software.  Due to the nature of the content and my (lack) of ability in AS3, I want the the coding to be really simple and still let the site look good.  The way the site is currently structured:
    1) Basic menu buttons that navigate to sections of the site (brings up a new page).
    2) Example, clicking on <Graphics> takes you to a new page and a sub-menu animates in (simple motion tween for the buttons to cascade down).  This animation is a movie clip placed on the main timeline.
    3) On the screen is also a slideshow for all the images within <Graphics>.  Instead of multiple small slideshows, I combined them all into one, so as to avoid complications with add / remove from stage.  There are prev / next buttons that keep images within their sub section (ie 1->2->3->1).  The sub-menu buttons are suppose to link to the start of each sub section, much like chapters on a DVD.  (The slideshow is a movieclip sub-nested in the menu movieclip).
    Main menu buttons work.
    Sub-menu animation works.
    Slideshow works.
    Can't get the sub-menu buttons to access the slideshow chapters.
    I have created and solved about half a dozen errors, and each time I fix something, it just causes another point to break.  I've gone around in circles for days, and not sure which was is up anymore.  So, while the slideshow works independently of the rest of the content, and I think I have the parent referencing correct, the problem I am currently facing is thus:
    TypeError: Error #1009: Cannot access a property or method of a null object reference.
        at 03graphics_fla::MainTimeline/frame1()
    I've browsed some other threads, and I think I know what the problem is.  Since the sub-menu is animated, the buttons do not appear on frame 1 of the nested timeline, while the actionscript is on frame 1 of the main timeline - thus the code doesn't exist yet when I click the button.
    Is this indeed the problem?  If so, how do I go about fixing it?
    Additionally, does the structure makes sense on how my site is organized?  Is there an easier / cleaner way to code it?
    (This thing is completely ghetto-rigged, I just need it to function - it's like my own little Millenium Falcon...)
    Cheers,
    Andy

    4. Everytime I run this, any test which is run first will fail and all other tests will pass.
    My Tests.as file is as below:

    All other tests are dummy tests which just asserts(true, true).
    I am not sure if I doing something wrong or forgot to take care of something.

        at peakInsights_fla::MainTimeline/frame1()[peakInsights_fla.MainTimeline::frame1:48]
    I guess it's telling me there's a problem with line 48 but what?
    The home, about, business, contact, and archives button works. On the business page there are the remaining buttons biotech, technology, real estate, and energy. when i test it; i get the finger but the buttons don't work. this is my first flash site so I'am new, new.

    I followed the steps and read some of your comments on the same top topic in another thread. When I put it on the first frame it was okay but the next button on that page had the same problem.  So what I am guessing is that I have to either create a document class or put the actions where the buttons are.  Am I understanding that correctly?  In the other thread in which you helped someone else; there was so comments about document class.  I found a tutorial on it and the way I understand it is that it you can put you actions in an external document.  But you have to include in the event listener the frame in which you want that action to happen.
    Thaks for your help.  And patience.

  • TypeError: Error #1009: Cannot access a property or method of a null object reference.

    Hi all,
    I am new to ActionScript and Flash, and I am getting this error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at jessicaclucas_fla::MainTimeline/stopResumescroll()
    I have several different clips in one movie that have scrolling content. When I click a button to move to a different clip that doesn’t have a certain scroll, it gives me this error. I cannot figure out how to fix this. You can see the site I am working on: http://www.jessicaclucas.com. I would really appreciate some help! Thank you in advance. Here is the code:
    //Import TweenMax and the plugin for the blur filter
    import gs.TweenMax;
    import gs.plugins.BlurFilterPlugin;
    //Save the content’s and mask’s height.
    //Assign your own content height here!!
    var RESUMECONTENT_HEIGHT:Number = 1500;
    var RESUME_HEIGHT:Number = 450;
    //We want to know what was the previous y coordinate of the content (for the animation)
    var oldResumeY:Number = myResumecontent.y;
    //Position the content on the top left corner of the mask
    myResumecontent.x = myResume.x;
    myResumecontent.y = myResume.y;
    //Set the mask to our content
    myResumecontent.mask = myResume;
    //Create a rectangle that will act as the Resumebounds to the scrollMC.
    //This way the scrollMC can only be dragged along the line.
    var Resumebounds:Rectangle = new Rectangle(resumescrollMC.x,resumescrollMC.y,0,450);
    //We want to know when the user is Resumescrolling
    var Resumescrolling:Boolean = false;
    //Listen when the user is holding the mouse down on the scrollMC
    resumescrollMC.addEventListener(MouseEvent.MOUSE_DOWN, startResumescroll);
    //Listen when the user releases the mouse button
    stage.addEventListener(MouseEvent.MOUSE_UP, stopResumescroll);
    //This function is called when the user is dragging the scrollMC
    function startResumescroll(e:Event):void {
    //Set Resumescrolling to true
    Resumescrolling = true;
    //Start dragging the scrollMC
    resumescrollMC.startDrag(false,Resumebounds);
    //This function is called when the user stops dragging the scrollMC
    function stopResumescroll(e:Event):void {
    //Set Resumescrolling to false
    Resumescrolling = false;
    //Stop the drag
    resumescrollMC.stopDrag();
    //Add ENTER_FRAME to animate the scroll
    addEventListener(Event.ENTER_FRAME, enterResumeHandler);
    //This function is called in each frame
    function enterResumeHandler(e:Event):void {
    //Check if we are Resumescrolling
    if (Resumescrolling == true) {
    //Calculate the distance how far the scrollMC is from the top
    var distance:Number = Math.round(resumescrollMC.y - Resumebounds.y);
    //Calculate the percentage of the distance from the line height.
    //So when the scrollMC is on top, percentage is 0 and when its
    //at the bottom the percentage is 1.
    var percentage:Number = distance / RESUME_HEIGHT;
    //Save the old y coordinate
    oldResumeY = myResumecontent.y;
    //Calculate a new y target coordinate for the content.
    //We subtract the mask’s height from the contentHeight.
    //Otherwise the content would move too far up when we scroll down.
    //Remove the subraction to see for yourself!
    var targetY:Number = -((RESUMECONTENT_HEIGHT - RESUME_HEIGHT) * percentage) + myResume.y;
    //We only want to animate the scroll if the old y is different from the new y.
    //In our movie we animate the scroll if the difference is bigger than 5 pixels.
    if (Math.abs(oldResumeY - targetY) > 5) {
    //Tween the content to the new location.
    //Call the function ResumetweenFinished() when the tween is complete.
    TweenMax.to(myResumecontent, 0.3, {y: targetY, blurFilter:{blurX:22, blurY:22}, onComplete: ResumetweenFinished});
    //This function is called when the tween is finished
    function ResumetweenFinished():void {
    //Tween the content back to “normal” (= remove blur)
    TweenMax.to(myResumecontent, 0.3, {blurFilter:{blurX:0, blurY:0}});

    Hi again,
    Thank you for helping. I really appreciate it! Would it be easier to say, if resumescrollMC exists, then execute these functions? I was not able to figure out the null statement from your post. Here is what I am trying (though I am not sure it is possible). I declared the var resumescrollMC, and then I tried to put pretty much the entire code into an if (resumescrollMC == true) since this code only needs to be completed when resumescrollMC is on the stage. It is not working the way I have tried, but I am assuming I am setting up the code incorrectly. Or, an if statement is not supposed to be issued to an object:
    //Import TweenMax and the plugin for the blur filter
    import gs.TweenMax2;
    import gs.plugins.BlurFilterPlugin2;
    //Save the content's and mask's height.
    //Assign your own content height here!!
    var RESUMECONTENT_HEIGHT:Number = 1500;
    var RESUME_HEIGHT:Number = 450;
    var resumescrollMC:MovieClip;
    if (resumescrollMC == true) {
    //We want to know what was the previous y coordinate of the content (for the animation)
    var oldResumeY:Number = myResumecontent.y;
    //Position the content on the top left corner of the mask
    myResumecontent.x = myResume.x;
    myResumecontent.y = myResume.y;
    //Set the mask to our content
    myResumecontent.mask = myResume;
    //Create a rectangle that will act as the Resumebounds to the scrollMC.
    //This way the scrollMC can only be dragged along the line.
    var Resumebounds:Rectangle = new Rectangle(resumescrollMC.x,resumescrollMC.y,0,450);
    //We want to know when the user is Resumescrolling
    var Resumescrolling:Boolean = false;
    //Listen when the user is holding the mouse down on the scrollMC
    resumescrollMC.addEventListener(MouseEvent.MOUSE_DOWN, startResumescroll);
    //Listen when the user releases the mouse button
    stage.addEventListener(MouseEvent.MOUSE_UP, stopResumescroll);
    //This function is called when the user is dragging the scrollMC
    function startResumescroll(e:Event):void {
    //Set Resumescrolling to true
    Resumescrolling = true;
    //Start dragging the scrollMC
    resumescrollMC.startDrag(false,Resumebounds);
    //This function is called when the user stops dragging the scrollMC
    function stopResumescroll(e:Event):void {
    //Set Resumescrolling to false
    Resumescrolling = false;
    //Stop the drag
    resumescrollMC.stopDrag();
    //Add ENTER_FRAME to animate the scroll
    addEventListener(Event.ENTER_FRAME, enterResumeHandler);
    //This function is called in each frame
    function enterResumeHandler(e:Event):void {

    Dear Sir,
    I really need your valuable assistance i was about to finish a project but at very last moment i am stuck. Here is the explanation below...
    I have two files called "holder.swf" and "slide.swf" i want to improt the "slide.swf" using this action below
    var myLoader:Loader = new Loader();
    var url:URLRequest = new URLRequest("slide.swf");
    myLoader.load(url);
    addChild(myLoader);
    myLoader.x = 2;
    myLoader.y = 2;
    Also i have attached the flash file of "holder.swf". My concern is the moment i am calling the "slide.swf" inside the "holder.swf" it is showing the following error...
    " TypeError: Error #1009: Cannot access a property or method of a null object reference.

  • Preloader :Error #1009: Cannot access a property or method of a null object reference.

    Hi,
    I'm having a lot of trouble getting a preloader to work on my Flash website. I'm new to actionscript, the site works fine but when I place the preloader in frame 1, I get.
    Error#1009: Cannot access a property or method of a null object reference.
    Then it lists three areas. The buttons on the site don't work anymore.
    I've followed the Lynda com tutorials so don't know what is causing this error.
    Included is the word.doc with the error code, preloader code, the main flash frame 2 code and the debug information.
    Any help would be great.
    Thanks!

    You need to make sure 'cards' is named properly and is present when that line of code executes.  If it is somewhere down a timeline, it is not present.
    As far as your preloader code goes, what is infoLoader.  I have to assume it's some form of component since you don't have any code to instantiate it.

    I found a related bug reported on Jira: https://bugs.adobe.com/jira/browse/FLEXDMV-1631
    But in our case, we have no zoom effect.  It may be timing related, as there is a lot of computation going on when this page, and the ADG is first initialised.
    Please?... Any suggestions or workarounds?  We don't want this falling over in the hands of our customers.
    <rant> And people wonder why I hate Flex!?  These obscure instabilities never happen when I develop Pure ActionScript.  The Flash platform is wonderfully stable.  But as soon as you bring Flex into play, things take longer to develop, it's a struggle to extend or change the behaviour of the bloated components, and everything falls apart as these bugs begin to surface.</rant>

    facing the same problem... sdk 4.1. no solution for about 2 years ????

    can anyone give me a helping hand?
    thanks in advance.

    use:

  • Module Chart component Error #1009: Cannot access a property or method of a null object reference

    Is there a known bug when displaying a chart component that is defined in a module. When attempting to display a chart component defined in a module it crashes indicating Error #1009: Cannot access a property or method of a null object reference.
    It crashes at the following location in ChartBase.as. Somehow when loading the chart the  styleManager.getStyleDeclaration("mx.charts.chartClasses.ChartBase"); returns null so when using the setStyle methods the exception occurs.
    private function initStyles():Boolean
            HaloDefaults.init(styleManager);
      var chartBaseStyle:CSSStyleDeclaration = styleManager.getStyleDeclaration("mx.charts.chartClasses.ChartBase");
      chartBaseStyle.setStyle("chartSeriesStyles", HaloDefaults.chartBaseChartSeriesStyles);
      chartBaseStyle.setStyle("fill", new SolidColor(0xFFFFFF, 0));
      chartBaseStyle.setStyle("calloutStroke", new SolidColorStroke(0x888888,2));
            return true;
    Added note: There is a chart component in the application that works fine.  The only way I can get  the chart in the module to display is to add the following workaround preinitializer but it severly impacts the loading of the module. Is there a way around this.
    protected function preinitializeHandler(event:FlexEvent):void
       var styleObjects:Array = FlexGlobals.topLevelApplication.styleManager.selectors;
       for each(var styleObj:String in styleObjects)  {
        var style:CSSStyleDeclaration = FlexGlobals.topLevelApplication.styleManager.getStyleDeclaration(styleObj);
        styleManager.setStyleDeclaration(styleObj, style, true);

    What do i have to do?

    I solved the issue by getting rid of the creationCompleteHandler event handlers for the KPI charts. But, since I am just days into flex development, I would be indebted if someone could explain to me why that was creating problems.
