Jbo null pointer exception whilst creating an AM

Hello,
I am trying to create some EO's,VO's and associated AM. At the end of the creation, I tend to get the following error
Load Error
Exception: oracle.jbo.dt.objects.JboException(java.lang.NullPointerException).
The creation of EO's runs smooth, but if I decide to create the associated VO's and the AM, the application hangs, and I have to kill it before I can move forward.
Please guide me

I am sorry I was ambiguous in my previous post.
I am trying to create a EO/VO/AM triplet for a host of tables using JDev 11g, and the tables under the 'mct' database.
I followed the following steps to create my triplet.
1. Using the EO wizard, I selected a host of tables, for instance, MCT_CONFIG_CONTACT_CENTER_VL from the MCT db
2. Following the usual steps, I tend to get the null pointer exception, with a 'load error' for one of the classes contained in a zip file, which I do not think I'm using, in the creation of the EO.
In the light of the above scenario, can you please guide me?

Hi,
Did you create Product/Software Components in SLD? And did you define dependencies(the three standard SAP SCs) for the SC in SLD? Did you update CMS after you've created SCs/dependencies in SLD?
Thanks,

Null pointer exception with ImageToBuffer.create(........)

I'm trying to draw two lines on received video frames so I implemented an effect that takes a frame then :
frame = Buffer -> Image -> BufferedImage -> draw lines -> Image -> Buffer ( Problem ).
the problem is in converting the Image back to Buffer in order to assign it as the Effect outcome buffer ( which will be showed ), the process function code is as followed :
BufferToImage bti;
ImageToBuffer itb;
public int process(Buffer inBuffer, Buffer outBuffer)
Object data = inBuffer.getData();
if (bti == null)
bti = new BufferToImage( (VideoFormat) inBuffer.getFormat());
Image image = bti.createImage(inBuffer);
if (image != null)
Graphics2D g = bImage.createGraphics();
g.drawImage(image, null, null);
g.drawLine(160, 0, 160, 240);
g.drawLine(0, 120, 320, 120);
if (itb == null)
itb = new ImageToBuffer();
Image i = Toolkit.getDefaultToolkit().createImage(bImage.getSource());
if (b == null)
b = new Buffer();
b = itb.createBuffer(i, 15); ///causes null pointer exception
if (b != null)
inBuffer.setData(outBuffer.getData());
outBuffer.setData(b.getData());
else
inBuffer.setData(outBuffer.getData());
outBuffer.setData(data);
// Copy the input attributes to the output
outBuffer.setFormat(inBuffer.getFormat());
outBuffer.setLength(inBuffer.getLength());
outBuffer.setOffset(inBuffer.getOffset());
return BUFFER_PROCESSED_OK;
Any solutions for the problem.
Thank you for replying in advance..

thanks Timo
through this URL i get possible deletion methods...
pls give more Information about the concept of removeRowWithKey, setCurrentRowWithKey, setCurrentRowWithKeyValue operation.... Just For Knowledge....

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">
 
 <f:facet name="app_model.listToDoAppsVO">
 
 <af:outputText value="#{node.Appname}" id="ot_app">
 </af:outputText>
 </f:facet>
 <f:facet name="app_model.listToDoTypesVO">
 
 <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):
java.lang.NullPointerException

Any ideas please? I'm using JDeveloper 11.1.2.1.0 incidentally...
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. Expected oracle.adf.view.rich.component.fragment.UIXInclude$IncludeContextChange, but got UIXCollection.CollectionComponentChange[Component class: oracle.adf.view.rich.component.rich.data.RichTree, component ID: pt_t8].

9.3.3 Upgrade, null pointer exception when accessing business rules and mac

Hello,
We upgraded from 9.3.1 to 9.3.3. In the Essbase Administration Services Console, when I attempt to access business rules or macros from a client PC, we get a null pointer exception. The message does not tell us much, but I cannot find more.
I can access business rules and macros using EAS Console from the server. Do I have a bad installation, or have I missed a step?
Thank you,

Hi,
You might have to re-organize your application module hierarchy to place your common code.
If your intension is to auto populate the primary key for your Entity Objects., I would suggest below common practice.
1). Create a Base Entity Impl class for your project that extends oracle.jbo.server.EntityImpl
2). Code your getDbSequence() method inside this base entity impl class
3). Make sure that all your Entity Objects extend your base entity impl class
4). Use EL expression to call this method for auto-generating primary key attribute of your Entity Object.
e.g., adf.object.getDbSequence("sequenceName")
Regards,
Eshwar

Null Pointer Exception and Illegal Arguement when ran with Wireless Toolkit

The following code throws a null pointer exception after it tried to initialize the textBox. I am not sure if there is something I am not importing, or if it's just because I'm sick and my head is cloudy. :-}.
I am using Wireless Toolkit 2.2 and Java 5.0
Anyhelp would be appreicated. Thank You.

Hi zoya,
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 :)

Null Pointer exception returned when object is not null!

I've isolated the problem and cut down the code to the minimum. Why do I get a null pointer exception when the start method is called, when the object objJTextField is not null at this point???? I'm really stuck here, HELP!
(two small java files, save as BasePage.java and ExtendedPage.java and then run ExtendedPage)

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,

JAX-WS Client throws NULL Pointer Exception in NW 7.1 SP3 and higher

All,
My JAX-WS client is throwing an exception when attempting to create a client to connect to the calculation service. The exception is coming out of the core JAX-WS classes that are part of NetWeaver. (see exception below)
Caused by: java.lang.NullPointerException
 at com.sap.engine.services.webservices.espbase.client.jaxws.core.SAPServiceDelegate.createDispatchContextExistingPort(SAPServiceDelegate.java:440)
 at com.sap.engine.services.webservices.espbase.client.jaxws.core.SAPServiceDelegate.createDispatchContext(SAPServiceDelegate.java:475)
 at com.sap.engine.services.webservices.espbase.client.jaxws.core.SAPServiceDelegate.createDispatch(SAPServiceDelegate.java:492)
 at com.sap.engine.services.webservices.espbase.client.jaxws.core.SAPServiceDelegate.createDispatch(SAPServiceDelegate.java:484)
 at javax.xml.ws.Service.createDispatch(Service.java:166)
I have done some research and it appears that as of NetWeaver 7.1 SP3 SAP stopped using the SUN JAX-WS runtime and implemented their own SAP JAX-WS runtime. I also took the time to decompile the jar file that contained the SAPServiceDelegate class which is throwing the null pointer exception. (see method from SAPServiceDelegate below)
 private ClientConfigurationContext createDispatchContextExistingPort(QName portName, JAXBContext jaxbContext)
 BindingData bindingData;
 InterfaceMapping interfaceMap;
 InterfaceData interfaceData;
 bindingData = clientServiceCtx.getServiceData().getBindingData(portName);
 if(bindingData == null)
 throw new WebServiceException((new StringBuilder()).append("Binding data '").append(portName.toString()).append("' is missing!").toString());
 QName bindingQName = new QName(bindingData.getBindingNamespace(), bindingData.getBindingName());
 interfaceMap = getInterfaceMapping(bindingQName, clientServiceCtx);
 interfaceData = getInterfaceData(interfaceMap.getPortType());
 ClientConfigurationContext result = DynamicServiceImpl.createClientConfiguration(bindingData, interfaceData, interfaceMap, null, jaxbContext, getClass().getClassLoader(), clientServiceCtx, new SOAPTransportBinding(), false, 1);
 return result;
 WebserviceClientException x;
 x;
 throw new WebServiceException(x);
The exception is being throw on the line where the interfaceMap.getPortType() is being passed into the getInterfaceData method. I checked the getInterfaceMapping method which returns the interfaceMap (line above the line throwing the exception). This method returns NULL if an interface cannot be found. (see getInterfaceMapping method below)
 public static InterfaceMapping getInterfaceMapping(QName bindingQName, ClientServiceContext context)
 InterfaceMapping interfaces[] = context.getMappingRules().getInterface();
 for(int i = 0; i < interfaces.length; i++)
 if(bindingQName.equals(interfaces.getBindingQName()))
 return interfaces;
 return null;
What appears to be happening is that the getInterfaceMapping method returns NULL then the next line in the createDispatchContextExistingPort method attempts to call the getPortType() method on a NULL and throws the Null Pointer Exception.
I have included the code we use to create a client below. It works fine on all the platforms we support with the exception of NetWeaver 7.1 SP3 and higher (I already checked SP5 as well)
 //Create URL for service WSDL
 URL serviceURL = new URL(null, wsEndpointWSDL);
 //create service qname
 QName serviceQName = new QName(targetNamespace, "WSService");
 //create port qname
 QName portQName = new QName(targetNamespace, "WSPortName");
 //create service
 Service service = Service.create(serviceURL, serviceQName);
 //create dispatch on port
 serviceDispatch = service.createDispatch(portQName, Source.class, Service.Mode.PAYLOAD);
What do I need to change in order to create a JAX-WS dispatch client on top of the SAP JAX-WS runtime?

Hi Guys,
I am getting the same error. Any resolution or updates on this.
Were you able to fix this error.
Thanks,
Yomesh

JRC (upg. to CR4E) - Report w Subreport - Oracle DB - Null Pointer Excepti

Hi
We have a Crystal Designer/Developer Version 11.5.10.1263. We develop reports using this.
Most of the reports have SQL Command mode design with JNDI/JDBC connection. It gets deployed with our Web application. And during runtime, when users access these reports from our web application, we typically use Java Reporting Component with Crystal Report Viewer SDK to open and display the report to the user.
Besides other issues, current problem I am having is:
I have a sub-report in my report. I am connecting to Oracle database. If this sub-report does not return any rows, I was getting a Null Pointer Exception. This seems to be a known bug. This happened to us when we had just the above mentioned components.
We recently upgraded just the JAR libraries to the ones packaged in CR4E (Crystal Reports For Eclipse) - initially to get more exporting capability.This upgrade gets us past the Null Pointer Exception issue.
Now, I am getting an error like "Unexpected database connector error". Please see the exception stack trace below if needed. Since we are a product and this display is specific to one out of about 100 different clients; with all the time we spent on making this report stuff work against this oracle DB client, we had finally ended up creating the display in JSP into our general product just for one of about 100 clients. Client must be the Lucky one...As a developer, I felt really frustrated.
One note:- SQL Server DB works perfect.
Other thing - Do we need to change any API calls after upgrading the JARS from standard JRC/Viewer to CR4E package?

I have exactly the same problem. Had posted it on the forum last week, but haven't received any response yet. I just file a single support case ($195) with SAP. If I hear anything useful back, will keep you posted. Please let me know if you are able to resolve the problem.
In my case, I can get my report to work with a single subreport. When I put multiple subreports, I get the same error as you are currently getting.
Check if your report has any special section formatting (conditional suppression etc). Try to remove those to see if it helps at all.

Null pointer exception while executing a scenario from cloned work repo

Hi,
I have involved in ODI 10g to 11g migration activity.
For doing that activity, i cloned the existing master and work repositories into some intermediate master and work schemas.
Created new configuration settings for pointing the odi 10g to the intermediate master and work repositories.
Everything is fine till this, but while executing any interface or package anything from intermediate work repo designer, am facing error as below

Note: My previous and cloned Master's work's repository id are same
Could anyone pls help on this.
Thanks in advance..

The error is resolved by following the below solution
If you receive an error in ODI 10g like;
java.lang.Exception: Error during Session launching
at com.sunopsis.dwg.dbobj.SnpSession.remoteExecute
or
java.lang.NullPointerException
at com.sunopsis.dwg.cmd.DwgCommandBase.prepare(DwgCommandBase.java)
1.First check whether your agents are working and test connection to repositories. If everything ok, you might have changed your repository name recently.
2.When you export your work and master repository and import to another schema or database and whether you connect to your imported repository, you change your repository name in your first environment.
3.Correct order is first rename your Master Repository name, log off / log on and change your Work Repository name and check below fields in both your Master and Work Repositories in both environments.
Master Repository : SNP_REM_REP
Work Repository : SNP_LOC_REPW
REP_NAME column of MASTER_REP.SNP_REM_REP should be equal to REP_NAME column in WORK_REP.SNP_LOC_REPW.
You cannot see WORK_REP.SNP_LOC_REPW value in ODI Topology Manager and if you are changing your repository name you need to update value from database.
Change the value from DB, loggoff and logon the user and connect the designer again.

Problem in getEelementById() method-null pointer exception

Hi All,
I am using DocumentBuilder factory for parsing a xml file.
I am getting the document object and also creating an element in
the root element .And also I am setting the element id for the
element as attiribute .I need to select the element having same ID
using getElementById() method .But it is giving null pointer
exception.
N.B: My parsing file contains dtd declaration and root element.
My sample code look like this;
DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();
DocumentBuilder db=dbf.newDocumentBuilder();
Document doc=db.parse(ne File("C:/index.xml");
Element root t=doc.getDocumentElement();
root.setAttribute("ID","12345");
Element oElement = doc.createElement(element_name);
oElement.setAttribute("ID",element_id);
Element oEle=doc.getElementById(element_id);
Could anyone please to solve this problem.
Please do favour with me.
Thanks and Regards,
Sreekanth

while creating xml you should mention which attribute is ID attribute using
setIDAttribute() method,
as you are setting "ID" attribute as ID so
after adding Id attribute to the root element
use setIDAttribute("ID",true);
then getElementById will return the element by using ID

I can't figure out why I'm getting a Null Pointer Exception

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.
Thanks,
