Cats webdynpro - Null Pointer Exception

Hi all,
I am running cats webdynpro application (ess~cat/CatDataRecord) using the portal testid and getting the below dump:
java.lang.NullPointerException
    at com.sap.xss.hr.cat.record.vac.calendar.VcCatCalendarView.wdDoModifyView(VcCatCalendarView.java:181)
    at com.sap.xss.hr.cat.record.vac.calendar.wdp.InternalVcCatCalendarView.wdDoModifyView(InternalVcCatCalendarView.java:338)
    at com.sap.tc.webdynpro.progmodel.generation.DelegatingView.doModifyView(DelegatingView.java:78)
    at com.sap.tc.webdynpro.progmodel.view.View.modifyView(View.java:337)
    at com.sap.tc.webdynpro.clientserver.cal.ClientComponent.doModifyView(ClientComponent.java:481)
The below config is done in the backend:
1. Cats profile created
2. Assigned CVR parameter
3. Maintained IT105
Is there any other config that is missing to solve the above dump and get the ESS screen running?
Thanks
Kukku

Hi,

    HI
      Null Pointer Exception can occur in may instances , for suppose
      1) when  you create a Value Node with some attribute which has cardinality , and you have not
      initialized the Node , then it would through  Null Pointer exception ,
      2) when you integrate the RFC and parameters you pass as input to the RFC are not set correctly
          then there could be null pointer when you execute the RFC
      3>or may be when you doesnot bind the node when using webservice then there could be null pointer exception
    and there could be many occurances  for the exception

    Just wondering if this can be solved on my end or is this a glitch? Would really appreciate some inputs!
    Thanks!

    Hi,
    Here two possibility
    1. This  is the case when we get something as return form the BAPI/RFC and want to display in our message area but return message itself is null like this statement
    wdComponentAPI.getMessageManager().reportException(wdContext.nodeOutput_Salesorder_Create().currentOutput_Salesorder_CreateElement().getSalesdocument());
    2.And this is when
      try
                   executableClazz.execute();
                   nodeToinvalidate.invalidate();
              } catch (WDDynamicRFCExecuteException ree)
                   wdComponentAPI.getMessageManager().reportException(ree);
                             or
    wdComponentAPI.getMessageManager().reportException(ree.getMessage);
    3. Message Area is simple UI element which ensure only the place where we have to so the message
    So Check your code again it might solve your problem
    Best Regards

    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,

  • Popup window null pointer exception

    Hi,
    I have created a web dynpro application like this: a first window with a button that calls a popup with user info and telephone number and a button OK.
    When I click on OK, the popup window close perfectly, but if I click again on the button of the first page to see again the popup, I get a null pointer exception error:
    The initial exception that caused the request to fail, was:

    IWDWindow window = wdContext.currentPopupNodeElement().getPopupAttribute();
    window.hide();
    window.destroyInstance();
    Has any one got any solution, I would really appreciate your help.

    Hi,
       Try changing your code like this under popup.
            IWDWindowInfo windowInfo = wdComponentAPI.getComponentInfo().findInWindows("PopWin");
         IWDWindow myPopup = wdComponentAPI.getWindowManager().createModalWindow(windowInfo);
    wdContext.currentPopupNodeElement().setPopupAttribute(myPopup);
         myPopup.setWindowPosition(200, 200);
         wdContext.currentPopupNodeElement().setPopupAttribute(myPopup);
         wdContext.currentPopupNodeElement().setUserName("thibault");
         wdContext.currentPopupNodeElement().setUserTelNumber("01010101");
    myPopup.show();

    Is there a reason why this is and how do I get by it.
    ii. Can I just add the field directly within the MDS>file/user.xml? Would there be an issue with changing an existing attribute metadata using the user.xml?

    Pradeep thank you for your response. it was helpful. However, I also found the responses to both my questions.
    i. The null pointer exception was due to using a complex query I was using in the LOV query. I tried a simple query and that worked fine.
    ii. For modifying the user defined attributes one can consult the following forum post:
    OIM 11g - Change UDF Field Type form String to LOV
    Thanks

  • REG : Null Pointer Exception for RFC values

    Hi All,
    I am facing peculiar erro in code.I need to check the null entries in SAP server then it should be replaced by space and if not null then should be replaced by the value in backend.But it is throwing null pointer exception
    I am using equalsignore case(null) and trim for space.
    I am not getting why its is throwing null pointer  exception.Kindly advise
    Regards,
    Anupama

    Hi
    Use
    String f = null ;
    if(f!==null)
    Wdcomponent.getMessageManager.ReportException ("this will cause null pointer exception  "+ f.length());
    Better to give it any Constant like
    priveate static final String NULL_CHECK  = "DEL_VAL12";
    rather than space ,at the time of chceking see if it has  DEL_VAL12 if true then put the actual data else let it be there.
    Best Regards

    PLease Help me !!
    I need this urgently.

    can you explain what your program tries to do... and
    at where it went wrong..Sir,
    We are trying to make an project where we can make a person register in our data base & after which he/she can search for other user.
    The logged in user can modify his/her own data but can view other ppl's data.
    We are in a phase of registering the user & that's where we are stuck. The problem is that after the login screen when we hit register (OK- button) the data are not getting entered in the data base.
    Can u please help me??
    I am using "jdk1.3' - studnet's edition.
    I am waiting for your reply.
    Thanks in advance & yr interest.

  • Null pointer exception and servlet

    I cant figure out why i am getting a null pointer exception. this works if i keep my form output in the same class as my driving servlet. All i did was break off the html display to a new form and i get a null pointer exception.
    this is just an excerpt. no reason to post the whole form.

    }

    anyway to write the system.err to an html screen with
    a servlet?Why would you ask that? Surely you should have asked "Any way to write a stack trace to an HTML screen from a servlet?"
    And in fact there is. I am sure you have not yet looked up the Exception class and the versions of its printStackTrace() method. But when you do, you will see that there are printStackTrace(PrintStream) and printStackTrace(PrintWriter). And you know how to write HTML (or text in general) to the servlet response so that it shows up in the client's browser, right? I will let you figure out how to put those things together.

    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!

    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<i>.getBindingQName()))
                    return interfaces<i>;
            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,

  • 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.
