What is actually throwing the NullPointerException? rs.getMetaData() or table.setModel()?

Table Model:: Null Pointer Exception

I have made an application wherein I am using a JTree to display some hierarchy.
Now while scrolling the tree,I display the details in the table.
Data for both the components come from the database.If I continously scroll up and down for some time
in the Tree I get an error in the Table Model
rsmd=rs.getMetaData();
for the above line.It throws NullPointerException,it only happens after scrolling for some time and
not for any particular value.
I update the table model using jtable.setModel().
Plz help.

What is actually throwing the NullPointerException? rs.getMetaData() or table.setModel()?

Java Null Pointer Exception while Importing a Table to IS

Hello All,
I am trying to import a table into IS and receiving a JAVA Null Pointer Exception. The table is in a Teradata database and I am able to import other tables belonging to the same schema.I get the Java error only while trying to import this one particular table. The DBA has confirmed that the table belongs to the schema/owner I am using. In any case, it seems more of a application error than a database level error. Can anyone provide any insight? Thank you in advance.

hi Keerthi,
thank you.
i tried with below code but still unsuccesfully
+ oaDFF = (OADescriptiveFlexBean)oawebbean.findIndexedChildRecursive("ActFlexField");+
oapagecontext.writeDiagnostics(this, "Niccal: i got DFF handle", 1);
OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
oapagecontext.writeDiagnostics(this, "Niccal: before if", 1);
i am able to print 1° comment line but not second. so i think it's something wrong getting the segment handle.
anyway i'm not able to reach your suggested if statement because execution stops before.
Infact, if i comment line :OAMessageTextInputBean mtib = (OAMessageTextInputBean)oaDFF.findChildRecursive("ActFlexField0");
page doesn't give error and saves data.
any suggestion appreciated,
thanx,

Null Pointer Exception When Adding New Row on Table

Hello JheadStart Team
I have used detail group with table layout , when I am clicking on AddRow button on detail table , I encounter NulllPointer Exception . I have traced the code and fount that in JhsCollectionModel when adding new row following
condition occurs :
DCIteratorBinding ib = getRangeBinding().getIteratorBinding();
int rangeSize = ib.getRangeSize();
int rowsInRange = ib.getAllRowsInRange().length;
because getAllRowsInRange is Null then the error raise.
My JheadStart ver is 10.1.3.3.85 .
Detail Group with table layout setting is :
Use Table range=true
Show New Row at top=true
New Rows:empty
Show Add New Row Button :true
Regards

Given the build you are using, I assume you are an Oracle employee.
Is this correct? if so, please post your question to the [email protected] mailing list.

Hello ppaulf,
Your problem is in your ExtendedPage.java file. You can fix this by changing the line
private JTextField objJTextField = null;to:
private JTextField objJTextField = new JTextField();This creates a proper instance.
Good luck,

Crystal report (crystalReportsViewer) crash with null pointer exception

Hi,
My application are simple : m_crystalReportsViewer.ViewerCore.ReportSource = report; but in throw exception null pointer when I call showDialog.
I see in code, we have method ShowTabHeader.
private void ShowTabHeader(bool isShow)
    Grid child = VisualTreeHelper.GetChild(this.tabViews, 0) as Grid;
    TabPanel panel = child.FindName("HeaderPanel") as TabPanel;
    if (!isShow)
        panel.Visibility = Visibility.Collapsed;
    else
        panel.Visibility = Visibility.Visible;
My problem : child.FindName("HeaderPanel") as TabPanel return null
=> if (!isShow)
        panel.Visibility = Visibility.Collapsed;
    else
        panel.Visibility = Visibility.Visible;
throws null pointer exception.
Do you have any idea about this?
Thanks.

A lot I don't understand in here... actually, I don't understand anything in your post:
When you call ShowDialog, what exactly are you trying to show? The code is the decompiled showtabheader method of the viewer. So, are you trying to override the viewer control and reportalbum? My guess is that the null reference is for the reportalbum's child object which is not the reportalbum object of the viewer. I don't understand why the code since its all handled internally to the viewer anyhow.
Perhaps searching the forum for code sample will help?
Also, see the [WPF Demo|http://www.sdn.sap.com/irj/scn/elearn?rid=/library/uuid/a09f7025-0629-2d10-d7ae-df006a51d1a8]

Null pointer exception while inserting a new row in ADF with jdev

Hi,
In ADF, I have retrieved some user information from LDAP server and I want to insert those values in to my table. But when I do this, I am getting a null pointer exception when I get the view object (ViewObject vo=getCRUIP002_1();). I am not sure why this happens.
Here is my code. It is urgent.
and please some one help me in fixing the issue.
ViewObject vo=getCRUIP002_1();
vo.clearCache();
vo.setMaxFetchSize(0);
vo.executeQuery();
Row newRow=vo.createRow();
vo.insertRow(newRow);
SearchResult res = (SearchResult)results.next();
Attributes attrs = res.getAttributes();
// Row newRow = vo.getCurrentRow();
newRow.setAttribute("LOGINNAME",(Object)attrs.get("sn").get().toString());
newRow.setAttribute("PASSWORDVALUE","x");
newRow.setAttribute("FIRSTNAME",(Object)attrs.get("sn").get().toString());
newRow.setAttribute("LASTNAME",(Object)attrs.get("sn").get().toString());
newRow.setAttribute("EMAIL",(Object)attrs.get("mail").get().toString());
Thanks,
Priya.S

assuming ur jdev version is 10.1.2
ViewObject vo=getCRUIP002_1();i dont think ur getting the view object hence null pointer expception.
ViewObject vo = findViewObject("MyView1");
if u r in the object class then first get the root application module and then access the View obejct from there.
In ADF if u assign a null value, u will always get the null pointer exception coz of java. Run the app in debug mode and check the values step by step, by the way there is not exception handling in ur code either, Do u know how to debug in Jdev ?

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.

The javadoc of createImage() states that "The return value may be null if the component is not displayable."
Not sure, but it may be that you need to call init() after this.setVisible(true).

Null pointer exception in com.crystaldecisions.sdk.occa.report.application.ControllerBase.checkViewReportRight

I am testing BOE 4.0 with a simple jsp based on the samples. The code is what I used to test BOE xi 3.1. But I ran into some report display inconsistencies with 3.1 so I am trying 4.0. The code below works in 3.1 But in 4.0, I get the report viewer screen coming up but get a null pointer exception coming to the screen.

Hi Jason,
Call any one of the methods
viewer.dispose(); or clientDoc.close();
Do not use both in BI 4.x version.
Test the same and let me know if it works.

Null Pointer exception in ToplinkDataControlProvider

Hi all,
I'm using Jdeveloper 10.1.3.0.4 and ADF Faces with Toplink. After creating a new database diagram with new tables and creating physical tables in database, I have created POJO files from database objects. There is no problem at this point but when I want to create xml data control files for POJO files. The null pointer exception is thrown in the jdeveloper dialog window.
thanks in advance
--barisk

Hi all,
This time , After I removed (deleted) 2-3 POJO files (model files) which is mapped against database tables, I have tried to create POJO files again but jdeveloper IDE has shown error message via popup window. The exception message is given below:
java.lang.NullPointerException

I couldn't create POJO files and after clicking OK button in popup window; the progress indicator in another window which indicates the creation of POJO files moves continuously.... So please tell me, in where do I make mistake?
best regards...

Null pointer exception in embedded component

Hi all,
I am trying to build a custom component that serves as a container. Unfortunately I consistently hit a null pointer exception in javax.swing.BufferStrategyPaintManager.flushAccumulatedRegion when my custom component contains a JPanel.
You'll find below the smallest code that reproduces the problem and the exception that comes with it.
In my testing I noticed few things:
- If the contained object is simple (a JButton for example), there is no problem.
- When I turn off double buffering, there is no problem.
- I figured out that I need to set the contained component size and its internal components to have it display properly.
I can't figure out what would make this work.
I'm using JDK 6.

Max Beans in Cache causes NULL Pointer Exception

Hi All,
a rather weird event (from our perspective) occurs when we do the
following:
We have an entity bean set to max beans in cache 100 (default value of
our deployment tool ), the database table related to that bean holds
lets say 300 entries.
Doing a find all and in the same session bean instanciated transaction a
processing loop over the enumeration of beans we get an NULL Pointer
exception when accesing the 101 Bean. Neverthless the Weblogic server
increases the cache size automatically but obviously not fast enough and
not on time.
has anyone experienced the same problem and has a fix for it, appart
from increasing the cache size in the deployment descriptor ?
any help welcome
Michael

Hi Michael.
Can you post the stack trace of the NullPointerException? Was it in
your code or ours? Also, what version of WebLogic are you using?

Thanks in Advance.

one important thing is that when i drag dynamic vo in jspx page running fine. but when i used it on fragment page(jsff) then Null poiner exception occur.
i am using following tutorial to create dynamic table.
https://blogs.oracle.com/shay/entry/adf_faces_dynamic_tags_-fora
is there any solution?
error is following-

Null pointer exception with inner class

Hi everyone,
I've written an applet that is an animation of a wheel turning. The animation is drawn on a customised JPanel which is an inner class called animateArea. The main class is called Rotary. It runs fine when I run it from JBuilder in the Applet Viewer. However when I try to open the html in internet explorer it gives me null pointer exceptions like the following:
java.lang.NullPointerException
at sun.java2d.SunGraphics2D.drawImage(SunGraphics2D.java:2761)

Do inner classes have to be compiled seperately or anything?
Thanks a million for you time,

I think that I am using the Java plugin ( Its a computer in college so I'm not certain but I just tried running an applet from the Swing tutorial and it worked)
Its an image of a rotating wheel and in each sector of the wheel is the name of a person - when you click on the sector it goes red and the email window should come up (that doesn't work yet though). The stop and play buttons stop or start the animation. It is started by default.
This is the code for the applet:
