Null pointer Exception in Standard Controller Extension
Hi All,
I extend the controller, The controller is related to two Standard pages.
My code is working fine for one controller, but where as for the other page it throws an error null pointer exception.
Please help me as this is very urgent issue.
My code is as follows:
// This Controller is used to display Item Description and manufacturer name, which is extended from Standard Controller EgoItemDetailPageLayoutCO

IOS default native extension packaging null pointer exception
I have an ANE that currently has a specific implementation for Android and a default implementation. Packaging up the .apk for android works fine on my android devices and packaging up a windows destop version (I created a separate desktop air application to do this) that uses the default ANE implementation works fine.
The problem is when trying to packaging the ipa for iOS that uses the ANE. I get the following error when I try a "Export Release Build" of my mobile app for iOS. It should be using the default ANE implementation.
Error occurred while packaging the application:
Warning: Using default implementation for native extension '<my ane extension id here>'
unexpected failure: null
java.lang.NullPointerException

What is missing? I've successfully packaged IPAs before but they didn't use any ANEs. This app will eventually have it's own iOS ANE implementation but it should just use the default if there is no iOS implementation available.
RandyWhile using ipa-test-interpreter or ipa-debug-interpreter (and also removing the -platformsdk argument during IPA packaging) fixed ipa-test and ipa-debug builds, it did not fix ipa-ad-hoc or ipa-app-store builds. Our entire build automation system relies on ant based builds, so at the moment using Flex 4.6 and AIR 3.4 is basically out of the question because of the null pointer exception error that eckhoff_randy pointed out above.
Without AIR 3.4 we do not have iOS 6 support (meaning we don't have iPhone 5 support either).
This is a MAJOR problem. I'm not sure that 'waiting until the next release' is an acceptable answer at this point. If possible can you give me as much information as you have on this problem?
Here's what's my output looks like:

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:

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 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. -
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.

Null pointer exception in ISimpleTypeModifiable
Hi
I am trying to add values to dropdownbykey dynamically using this code:
IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute("PROCESS");
ISimpleTypeModifiable processType = attributeInfo.getModifiableSimpleType();
processType.setFieldLabel("PROCESS");
IModifiableSimpleValueSet valueSet = processType.getSVServices().getModifiableSimpleValueSet();
Code is giving null pointer exception in the following line:
ISimpleTypeModifiable processType = attributeInfo.getModifiableSimpleType();
How to Solve it.Its urgent.
Points will be awarded.Actually the process is the attribute of node within context.
so i changed the code to:
IWDAttributeInfo attributeInfo = wdContext.nodeAuditNode().getNodeInfo().getAttribute("PROCESS") ;
ISimpleTypeModifiable processType = attributeInfo.getModifiableSimpleType();
processType.setFieldLabel("PROCESS");
IModifiableSimpleValueSet valueSet = processType.getSVServices().getModifiableSimpleValueSet();
The second point is: we can't modify the data type of mapped attribute in view controller.
So for that, we have to write that code in component controller. -
Null Pointer Exception in SessionData removeAttribute
Hi,
I am getting a null pointer exception while calling removeAttribute on the HttpSession. This happens pretty consistently (it does not give a null pointer some times).
All we are doing is removing a Struts Action Form from the session as it is a large one after going thru a wizard app. It has been frustrating as we have been facing this issue since 10 days and we have no clue what to do. The value objects with in the form are all serializable.
The stack trace is pasted below.
Any help will be greatly appreciated.

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. -
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 MHi 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 .
Regards

Creating SC dependencies result in null pointer exception
Hi
I have installed JDI landscape and am nearly finished but I encounter a null pointer exception when I tried to adjust dependencies for my newly created SC and as a result I cannot create a track (no SCs could be added to it).
The exception is as follows:

PLEASE help me out
ThanksHi,
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,

Using Back button causes Null Pointer exception
Hi,
I have done some customization by extending the seeded Controller on a Page.I have altered the View query and executed it again dynamically as its not a static query.
There is a functionality called compare which directs the users to a page from the page I have customised the controller.
If the user uses the back button to return to the previous page it is giving a Null Pointer exception.
Also refresh button causes a similar Null Pointer exception on the customised controller page.
can anybody throw some light?
Also is there a way to disable the back and refresh button on the page?Is the control entering the back button code in process request in your CO? Have you confirmed this by putting some debug comments?It many be that this error might being from the code where you have handled back button.
Put debugging comments and check.

Help please I get Null Pointer Exception with my SQL query
The following statement gives me a null pointer exception when executed
from the doPost of my servlet.
rs=stmt.executeQuery(sqlQuery);
The error message reads:
java.lang.NullPointerException
at stockserv.Servlet1.doPost(Servlet1.java:142)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:760)
===etc.
when I execute the same statement and query (same DB and table) from a standard java
program I do not get the error and get the propper result.
Any obvious thing I should check?
ThanksYes line 142 is as follows
rs=stmt.executeQuery(sqlQuery);
I also tried it with the folowing literal statement and get the same error.
rs=stmt.executeQuery("select * from table1 Where symbol= 'brt' ");
Does null pointer mean I am sending a null query or something else?
Again this same statment works from a regular java (non-server)program.
Thanks Again -
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

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.
