Java Callout in OSB failing with null pointer exception
Hi,
We have a requirement where we need to convert XML String to org.apache.xmlbeans.impl.values.XmlAnyTypeImpl type using java-callout, but value is not getting set when we are trying to do the same. Below is the code we are using in the java callout:
byte [] bArray = xml.getBytes();
InputStream is = new ByteArrayInputStream(bArray);
Reader reader = new InputStreamReader(is,"UTF-8");
InputSource iss = new InputSource(reader);
iss.setEncoding("utf-8");
xmlNode1 =
DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(iss);
XmlAnySimpleType xmlObj = XmlAnySimpleType.Factory.parse(n);
xmlAnyTypeImpl.set_newValue(xmlObj);
Node resNode = xmlAnyTypeImpl.getDomNode();
Can someonce please help for the same.
Regards,
Soumik
First check whether the java class that is called is able to read the string message that is passed by the proxy service.

MadhuI don't think OIM 11g supports DSML profile and may be that's the reason you are getting NPE.
See: http://docs.oracle.com/cd/E14571_01/doc.1111/e14309/spmlapi.htm#CHDCBJAI
It states:
"SPML has two profiles: the XSD profile and the DSML profile. This release of Oracle Identity Manager makes use of the XSD profile." -

What might be the issue?Hi Saurabh,
FimCustomization.exe keeps crashing for me as well. I figured out it is all about the accounts that you are using. I have wrote a blog post that shows the scenario that worked for me. Hope it will help you.

DTTestBed fails with Null Pointer Exception
Hi
I have installed Tim's DTTestBed on standalone OC4J version 10.1.3.2.0 using the JDK from Oracle JDeveloper10.1.3.3\jdk\bin.
Tim's installation calls for J2SE version 1.4.2.
I used the J2SE that Jdeveloper 10.1.3.3.
The Sample EMPLOYEES.xml in Tim's blog uploads fine, but after specifying the username/pw/host info and submitting, I get a 500 Internal server error in the browser and the following entry in the DTTestbed\application.log:-

SAP Portal Display Documents is hanging with Null Pointer Exception
Hi I am having problems with an iview from the products section of SAP standard iviews
In my portal page I have the following three iviews, find documents, display master data and display documents both the find docs and display master data work great, but the display documents seems to hang and a java Null Pointer Exception shows in the data frame of IE. It hangs up the whole page and I have to keep hitting back button to close the window and open. I have the following in config for web front end
DOC_OBJ is mapped to DOKAR, DOKNR, DOKVR and DOKTL with default set.
DOC_REQ is set to DOKAR default checked
EQUI_REQ is set to EQUI-EQUNR default checked
This is under SIMG_SPORT -> products -> select data fields for web front end
Am I missing something?
Cheers,
DevlinThe following code is your problem:
//-------construct
public void MySlide()
contents = new Tile[ROWS][COLS];
reset();
}Constructors don't return anything including void. Therefore you really aren't calling the above method as you assume in your main method as it is not a constructor. Remove the void keyword and your initializing code will execute properly. -
Help with Null Pointer Exception
Hi, I am working on a simple menu program. It compiles and works correctly except for one item. I am having a problem with Greying out a menu item...... Specifically, When I press the EDIT / OPTIONS / READONLY is supposed to Greyout the Save and SaveAs options. But, when I do that it displays a Null Pointer Exception error message in the command window.
Your advice would be much appreciated!
Now for the code
/ FileName Menutest.java

} // end class TestAction
} // end class MenuTestalan, I've been trying to figure out a solution.
You can initialize it like this
private Action saveAction= new Action();
private Action saveAsAction=new Action();
THE ABOVE WILL NOT WORK.
because Action is an interface. An interface does not have constructors. However, interface references are used for polymorphic purposes.
Anyway, all you have to do is find some class that implemets Action interface.... I cant seem to find one. Or maybe this is not how its supposed to be done?
Hopefully, someone can shed some light on this issue.
FYI,

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.

Edited by: duyhai707 on Jul 13, 2011 8:09 PMA 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]

Reflection problems with null pointer exception
I am having a problem with reflection. I keep getting a NullPointerException and can't figure out why.
It is happening when I call this:
ResponseObject result = (ResponseObject)method.invoke(classInstance, argArray);
I can't figure out what the problem is. I had this reflection working, and then I made some changes to how the argument array was created. In the end, the argarray is the same.
Any ideas?Also, the API for the method class says that a
NullPointerException is thrown if the object in the
first argument is null. I have tested for this, and
it is not null.does it? read again, because giving 'null' as the first argument is perfectly legal. how else would you reflectively invoke a static method, since you might not have an actual instance of the class to pass -

Thank youThe task parameters passed into a scheduled job are the parameters defined for the scheduled task definition in the metadata xml and configured in the scheduled job. They are not the data of an individual user as you seem to be trying to get. In a scheduled task I would expect some sort of search for users to operate on.

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 and Illegal Arguement when ran with Wireless Toolkit

Here is the problem:
tbHelp = new TextBox("HeLp", "You can press the back button", 25, 0);
This line declares a maximum textbox size of 25 but in reality he is declaring a textbox of size 29.
Thats why it is throwing the illegal argument.
happy coding :) -
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,
