Crystal Report throws NULL Pointer Exception from Java

Hi,
<br>
We are using crystal report in our application and we are changing the report datasource with the application datasource through our code. We are using CR4E 2008 to achieve this solution. We are getting a NULLPointerException, when we run the report in Oc4J(Oracle Apps Server) with JDK1.6. Could you please help us in achieving the solution

WPUMFactory.getUserFactory() throws null pointer exception

Hi,
I am trying to use KM API's to read files from KM repository. I am using the below code as mentioned in the blog: How to download KM documents using Web Dynpro Java
Below is my code:
IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();
IUser epUser = WPUMFactory.getUserFactory().getEP5User(sapUser);
However the line WPUMFactory.getUserFactory() throws null pointer exception. Can some one please help on why these happens as these seems to be the standard code to read a file from KM.
Thanks.
Regards,
Ponraj M

Hi Ponraj ,
Instead of fetching the current logged on user , use the below line to set the resource context and see if it helps .
com.sapportals.wcm.repository.IResourceContext resourceContext = ResourceFactory.getInstance().getServiceContext("cmadmin_service");
cmadmin_service is a existing user that can be used to access KM resources .

Vector.clear() throws null pointer exception

is there anything wrong in my code. when i try to clear the vector irrespective of whether i add elements to it or not, if there are no elements added to the vector v1.clear() it throws null pointer exception
Vector v1 = new Vector(1,1);
v1.clear()

And the guessing game continues... anyone for a shortctu to duplicate this problem?
public class NullVectorCreator
    private Vector v1;//just love the name, so clear and unambiguous... :)
    public NullVectorCreator
         Vector v1 = new Vector();//well done - a local variable masquerading as

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.

public void setFile(File f){

      this.f = f;

// do some stuff
Can anybody tell me what makes it to throw a null pointer exception.

Anyways, chances are there's an NPE being thrown from the constructor. What happens if you just instantiate it the old-fashioned, non-reflective way?

GetUserRoles in viewobject throws null pointer exception

Hello,
I've set up security for our jsf-adf-bc4j application.
I now want to get the user role in our viewobject.
I use the following code :
SessionImpl session = (SessionImpl) this.getDBTransaction().getSession();
String[] roles = session.getUserRoles();
for (String role : roles){
System.out.println(role);
This throws a null pointer exception at the"System.out.println(role);" line .
The user has a role (I can read the role in the viewcontroller project)
In the view object i can also get the session.getUserPrincipalName(). This works fine.
Can anybody help me with this problem ?

You define a local ArrayList here:public MonthlySchedule()
ArrayList<Request> monthlyschedule= new ArrayList<Request>() ;
}Just instanciate the instance variable.

Call to nodeInfo throws null pointer exception

I have a context node called Subst and want to bind a value set to one of its attributes using a modifiable simple valueset. So I called
wdContext.nodeSubst().getNodeInfo();
and got a null pointer exception because the nodeSubst is null. OK, I have cardinality 0..n, so at the moment I set the value set there is no node instance. But I want to set the value set for all node instances, not only for one. I changed the singleton property and it worked. But I don't understand why there is a difference between singleton or non-singleton and if it is important whether I have a value or model node.
Regards,
Josef

Hi Josef,
Cardinality talks about the collection of the node i.e the number of elements a node can have.
Singleton is about the existence of a node instance with respect to its parent or element collection.
One instance of a singleton child node exists at runtime for one parent node instance. The contents of the child node instance change depending on the lead selection in the parent node. Node instance existence is per node basis.
Whereas, for a non-singleton node, there will be as many number of node instances as there are elements in the parent node. So parent node's cardinality, say 0..n, there will exist n child nodes. So node existence in this case is per element basis.

Java function with Dynamic config throws null pointer exception

hi Experts,
   I am using dynamic config using java function in my message mapping.
The source message has a field called "fname".
The value of "fname" is the input to my java UDF.
The java UDF code is:
   public String getDynamicFile(String fname, Container container) throws StreamTransformationException{
   String str = fname + ".xml";
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey FileName = DynamicConfigurationKey.create("http:/"+"/sap.com/xi/XI/System/File","FileName");
conf.put(FileName, str);
return str;
   When I test this message mapping I get the following exception:
   Runtime Exception:[java.lang.NullPointerException: while trying to invoke the method com.sap.aii.mapping.api.DynamicConfiguration.put(com.sap.aii.mapping.api.DynamicConfigurationKey, java.lang.String) of an object loaded from local variable '<4>'] in class com.sap.xi.tf._<message mapping>_ method getDynamicFile[test, com.sap.aii.mappingtool.tf7.rt.Context@2e52cb31]
What am I doing wrong in this UDF?
Thanks
Gopal

Hi,
      Your UDF will run fine in an end to end execution,i.e, during runtime. However, if you want to test your message mapping test tab without the dynamic config UDF throwing an exception, encpasulate the code in a try catch block
public String getDynamicFile(String fname, Container container) throws StreamTransformationException{
String str = fname + ".xml";
try{
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey FileName = DynamicConfigurationKey.create("http:/"+"/sap.com/xi/XI/System/File","FileName");
conf.put(FileName, str);
}catch(Exception ex){}
return str;
The above code should run fine when you test in the message mapping test tab.
Regards

Hello,
Java Server Page is a technology that we use to
generate HTML dynamically and you use scriptlets to
perform this.
that's why you are not allowed to use awt or swing
packages.
all graphical components have to be an HTML component
(including applets).
Najib.Hi,
I know you are supposed to generate an HTML file, and I'm not creating a JFrame to display it. Let me explain how our application works: when the user presses a button in our page, we have to create a .pdf file and generate a page with a link to it so the user can download it.
This .pdf file has some charts (the charts and pdf are created with Sitraka's JClass Chart and PageLayout), and in order to embedd the chart in the .pdf file we need to put it first in a JFrame.
The code snippet is:
JFrame frame = new JFrame();
frame.getContentPane().add(chart);
frame.addNotify();
Image img = chart.snapshot();
frame.removeNotify();
frame.removeAll();
This works most of the time, but in this specific machine sometimes the instantiation of the JFrame fails with the error I posted before.
Hope I have made things more clear.
Wesley

I just started the Mapping Workbench and it works fine, so at a minimum, stopping and restarting the workbench will do it. Sorry but I don't know if closing and reopening the project will do the trick.

Null pointer Exception on java plug-in , using Mutity language...

hi all :)
I found at plug-in do not suppor Multy language.
for Example...
my operating System is Window XP and log in ID is not English ... like Korean, Chinese etc...
i programmed Web application with Swing Applet(JApplet)... and tested plug-in version 1.2.2 and 1.3.1 and XP plug-in
Plug-in said that like this.

... etc....
this message is plug-in do not download class archive in client System cache... because of VM cannot know user.home directory...
you can find that java plug-in does not support mulity language to see the next sentence.
"user home = C:\Documents and Settings\��????"
in this reason i found a problem in communication JApplet and java-script by using cookies...
How can I solve this problem...( i must use Multi language login ID plz.....)
have a nice day!!!
