Null pointer exception in toString!
Hi all,
i am getting null pointer exception in toString method.Might be due to threads.Can i synchronize toString?
The code snippent is as follows :
@Override
public String toString ()
if (mSourceInfo != null)
return "Source [Name=" + mSourceInfo.name + ", Description=" + mSourceInfo.description + ", Type=" + mSourceInfo.type + ", Path="
+ ", Online=" + mSourceInfo.online + ", Acknowledged=" + mSourceInfo.acknowledged + ", Tags=" + mSourceInfo.tags
+ ", Dimension:width=" + mSourceInfo.width + ", height=" + mSourceInfo.height + "SourceId=" + mSourceInfo.sourceId;
else
return "Source [Id=" + mObjectId + "]";
}

Make the following change:No! Don't! Sorry to say that, but this suggestion is bullshit.
1. there is no String constructor that takes any object.
2. sourceInfo definitely is not a String!
3. there is almost never a reason to use the String constructor that takes only a String (if you where trying to do that).
The correct solution would look something like this:
public String toString ()
// Get a local copy of this object so that the
// entire method is isolated from any changes
// in the global object
TypeOfSourceInfo tempSource = mSourceInfo;
if (tempSource != null)
return "Source [Name=" + tempSource.name + ", Description=" + tempSource.description + ", Type=" + tempSource.type + ", Path="
+ ", Online=" + tempSource.online + ", Acknowledged=" + tempSource.acknowledged + ", Tags=" + tempSource.tags
+ ", Dimension:width=" + tempSource.width + ", height=" + tempSource.height + "SourceId=" + tempSource.sourceId;
else
return "Source [Id=" + mObjectId + "]";
}Btw, it seems that the type of mSourceInfo should have a toString, which you could simply call here. Your code seems to do stuff that that Class should be doing instead.

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,

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.Sassuming 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. I'm still not finished with the program and I can't finish it until I know that this issue is resolved.

Not sure, but it may be that you need to call init() after this.setVisible(true). -
Java Null Pointer Exception- Business Validation In AM
Hi, I have been tried cracking this validation issue, tried several combinations. But does not work and throw java null pointer exception. I would appreciate if somebody can point where I am going wrong on the code. Thanks ahead.
Below is the issue:-
I have a page with PO (blanket purchase order) header info, and a PO line info with additional empty columns (related to Blanket Release). When the user fills in one of the columns (release amount, rls_amt_i), then I need to validate this against remaining blanket amount ie.{ PO_amt - (po_rls_amt1 + po_rls_amt2+..)}. If rls_amt_i is <= remaining amount, then the release needs to get created, otherwise shouldn't. I know, this is a pretty normal requirement. Please check my code to see where I could be wrong.
ReleaseCO (in PFR):-
if (pageContext.getParameter("Apply") != null)
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject vo = (OAViewObject)am.findViewObject("CxPoReleaseVO1");
Number poHeaderId = (Number)vo.getCurrentRow().getAttribute("PoHeaderId");
String poNumber = (String)vo.getCurrentRow().getAttribute("PoNumber");
OAViewObject linesVO = (OAViewObject)am.findViewObject("CxPoReleaseLinesVO1");
Number lineAmt = (Number)linesVO.getCurrentRow().getAttribute("Amount");
Serializable [] params = {poHeaderId.toString(), poNumber, lineAmt.toString()};
am.invokeMethod("apply", params);
ReleaseAM:-
public void apply(String poheaderId, String poNumber, String lineAmt)
Number blanketAmt, totalreleasesAmt, lineRlsAmt;
try
{ lineRlsAmt = new Number(lineAmt.trim());}
catch(Exception e) { throw new OAException("AK", "FWK_TBX_INVALID_EMP_NUMBER"); }
totalreleasesAmt = getReleasesAmt(poheaderId);
blanketAmt = getBlanketAmt(poNumber);
if ((lineRlsAmt.intValue() - (blanketAmt.intValue()-totalreleasesAmt.intValue())) <= 0)
getTransaction().commit();
approve();
throw new OAException("The amount is less than the remaining release amt", OAException.INFORMATION);
} // end apply()
public Number getReleasesAmt (String poHeaderId)
CxTotalReleaseQuantityVVOImpl totalreleaseqtyVO = getCxTotalReleaseQuantityVVO1(); //vo to get TotalReleased Amount
Number poHeadNum = null;
Number totalqty;
try { poHeadNum = new Number(poHeaderId); }
catch (Exception e) { throw OAException.wrapperException(e); }
totalreleaseqtyVO.initQuery(poHeadNum);
CxTotalReleaseQuantityVVORowImpl row = null;
row = (CxTotalReleaseQuantityVVORowImpl)totalreleaseqtyVO.getCurrentRow();
try { totalqty = (Number)row.getQuantityReleased();}
catch (Exception e) { throw new OAException(e.getMessage()); }
if(totalqty != null)
{ return totalqty; }
else
{ throw new OAException ("exception occurred", OAException.ERROR); }
public Number getBlanketAmt (String poNumber)
Number blanketAmt;
CxBlanketAmtVOImpl blanketVO = (CxBlanketAmtVOImpl) getCxBlanketAmtVO1(); //VO to get total amount on the BlanketPO.
blanketVO.initQuery(poNumber);
Row row = blanketVO.getCurrentRow();
blanketAmt = (Number)row.getAttribute("Quantity"); //gets the blanket amt
if( blanketAmt != null ) {
return blanketAmt ; }
else { throw new OAException ("exception occurred", OAException.ERROR); }
---------The code breaks at the line where I try to get "totalqty" or "blanketAmt" .. It throws a java nullpointer exception.
Thanks for helping me out.

The code breaks at the line 642: totalqty = (Number)row.getQuantityReleased();
I had already taken care of the null value in the VO sql query by using nvl(sum(release_amount), 0).. .so it should return atleast 0, if its null. But it returns "null" all the time.
I dont understand why its doing that. When I run the sql backend the query works fine and returns 0,even when there are no prior releases on the PO.
Thanks,

Hey guys,
Im having a problem with the following code:
public void testVariable(Object a, Object b)
if(a!=null || b!=null)
Object reta = null;
Object retb = null;
String tempa = null;
String tempb = null;
if(a.toString() !=null && b.toString() !=null) <---- Null pointer exception
tempa = a.toString();
tempb = b.toString();
tempa = tempa.toLowerCase();
tempb = tempb.toLowerCase();
}Im getting a null pointer exception when i do that if statement, ive narrowed it down and found that that was the problem but I have no idea why?
any suggestions ?if (a!=null || b!=null)...If a is not null, OR b is not null, do the following statements.
if( a.toString() !=null && b.toString() !=null ) ...Perform an operation on a, converting it to a string. This will throw a null pointer exception if a is null. If we survive that, see if the resulting string is null (toString methods should never return null here in fact).
Perform an operation b, converting it to a a string. This will throw a null pointer exception if b is null. If we survive that, see if the resulting string is null (toString methods should never return null here in fact).
So if either a or b is null, but the other one isn't, you will get a null pointer exception.

Hi,
I am having a problem with my module written for Enhancing functionality of file adapter.My module validates a input file for a particular record presence and if that record is present it would be processed normally by XI system.
But in case, if the input file doesn't contain the particular record the module is supposed to throw an exception and process shuld terminate.In this case XI shuldn't process the input file.
But in second case(File not containing the record) I am getting Null pointer exception in adapter monitor.Unable to see any message in auditlog since input file is not being read by file adapter.
My code is like this:
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData)
throws ModuleException {
// TODO Auto-generated method stub
//Declarations
Message mes = null;
XMLPayload xmlData = null;
DocumentBuilderFactory docBuilderFactory = null;
DocumentBuilder docBuilder = null;
Document doc = null;
AuditMessageKey amk = null;
boolean flag = false;
// Fetch the Message Data from Module Data
mes = (Message) inputModuleData.getPrincipalData();
// For Audit Log Fetch the Audit Message key from the message.
amk = new AuditMessageKey(mes.getMessageId(), AuditDirection.OUTBOUND);
Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "Amex Validation Module called");
xmlData = mes.getDocument();
InputStream instr = xmlData.getInputStream();
docBuilderFactory = DocumentBuilderFactory.newInstance();
try {
docBuilder = docBuilderFactory.newDocumentBuilder();
} catch (ParserConfigurationException e) {
// TODO Auto-generated catch block
Audit.addAuditLogEntry(amk, AuditLogStatus.ERROR, "Document Builder Factory not generated Properly");
try {
doc = docBuilder.parse(instr);
} catch (SAXException e1) {
// TODO Auto-generated catch block
Audit.addAuditLogEntry(amk, AuditLogStatus.ERROR, "Document Not generated Properly, SAX Exception called, May Data contains Error");
} catch (IOException e1) {
// TODO Auto-generated catch block
Audit.addAuditLogEntry(amk, AuditLogStatus.ERROR, "Document Not generated Properly, Input/Output Error");
NodeList record = doc.getElementsByTagName("Recordset");
for (int k = 0; k < record.getLength(); k++) {
Node recordnode = record.item(k);
NodeList list_rec = recordnode.getChildNodes();
for (int l = 0; l < list_rec.getLength(); l++) {
String headnodename =
list_rec.item(l).getNodeName().toString();
if (headnodename.equals("itemType9")) {
flag = true;
if (flag == true)
Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "Record Type 9 present in the file, Successfully Processed");
else{
Audit.addAuditLogEntry(amk, AuditLogStatus.ERROR, "Record Type 9 not present in the file, Not process further");
//throw exception
ModuleException e = new ModuleException();
throw(e);
return inputModuleData;Are you sure the following statement is going to work always ?
NodeList record = doc.getElementsByTagName("Recordset");
In case there are no nodes by the name <b>Recordset</b>, the very next block of code will throw a NullPointerException at the line
for (int k = 0; k < record.getLength(); k++) {
because, if record is null, record.getLength() would not work and throw NLP. -

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.

ta.getText();does anyone have any ideas as to what the problem is?
(NOTE: i am somewhat new to java, and am DEFINITELY new to swing. so, if there is a better way to go about the stuff that i'm trying to accomplish, PLEASE feel free to offer suggestions.)

}I changed my "actionPerformed" function a bit.
Thanks for your comments - I hadn't realized some mistakes I had made while trying to fix my code.
I'm still getting a null pointer exception, though.
Also, in the main function of GUI_CreateAntibody, I call init for GUI_CreateAntibody. Within THIS init function I call init for GUI_CreateAntibody_Sketcher. I don't understand what is wrong with this (except that I suppose I should be using constructors as opposed to init functions.)
Thanks,
Kim

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

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,
AnupamaHi
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.
