Java.lang.NullPointerException in 8.1 with soap doc literal binding

hi,
scenario:
1) web service with soap doc literal binding on external server. web service
is expecting a complex input argument
2) generate web service control in weblogic 8.1 (sp1) workshop
3) wrote jws file to use the web service control
4) run test and hit the following call stack
NOTE: this is only encountered when the web service is expecting a complex input
argument. if the web service is expecting a simple input argument, it works fine

Java.lang.NullPointerException ADF_FACES-60097 message ***WITH SOLUTION***

Hi Everyone:
We are on JDeveloper 11.1.2 & JHeadstart 11.1.2. When testing an application that had previously been written in 10g and migrated to 11g, then migrated again to 11.1.2 because our database has logical composite keys, we have found that if we manually inputted an invalid value into the inputtext box of a primary key that has an LOV on it, the following message came up.
"java.lang.NullPointerException
ADF_FACES-60097:For more information, please see the server's error log for an entry beginning with: ADF_FACES-60096:Server Exception during PPR, #"
with a random number displayed. We wondered where the java.lang.NullPointerException was coming from and then on a whim, tried to see if it couldn't find the error messages that were previously found in ApplicationResources_en.properties file in 10g. So I manually copied all of the error messages found in the ApplicationResources_en.properties file in 10g, into the end of the ApplicationResources_en.properties file on 11.1.2. There were only about 100+ messages in the 11g version of the ApplicationResources_en.properties file when there were almost 3,000+ messages in the 10g version of the ApplicationResources_en.properties. I then re-ran the job, and the proper error message comes out with no java.lang.NullPointerException message when I input an invalid value into the primary key (+Artransactioncode with this TransCode does not exist).+
Is this a known issue when converting from 10g to 11g?

Hi Everyone:
           I have done some further testing. We are using a re-usable Business Components .jar file to access our entities. We import the .jar file into the project and create the ViewObjects and ViewLinks from that .jar file.
            It APPEARS that a test case using the HRSchema and using the Entities & Associates generates the constraint error messages, but when I use the .jar file of re-usable business components imported into the project, those constraint error messages are not created in the ApplicationResources_en.properties file. I have created two testcases as well as the re-usable .jar file that I can send to you to show what I mean.
            This behaviour seems to have shown up in 11.1.2 as there was no problem before this.
             Please let me know where you'd like me to upload the testcases.
             Thank you.

security: Adding certificate in Deployment denied certificate store
security: Added certificate in Deployment denied certificate store
For another person at same IE level and JRE level it works fine and debug for that shows:
security: Certificate has failed the verification with the Internet Explorer ROOT certificates
security: Invalid certificate from HTTPS server
security: Adding certificate in Deployment session certificate store
security: Added certificate in Deployment session certificate store
security: Saving certificates in Deployment session certificate store
security: Saved certificates in Deployment session certificate store
Is there something wrong with the "Deployment session certificate store" in the first instance? Treid un/reinstalling the JRE but it didn;t fix things.

Regenerate what certificate? The applet is unsigned.
Plus other people with the same IE level and same JRE level do not have this problem, which leads me to think it is something specific to this user, like maybe the deployment session certificate store. Is that a file someplace we can like delete to start clean?

Receive java.lang.NullPointerException (JCA-12563) on SCA with Stored Procedure dbAdapter (SOA Suite 12.1.3)

Hi,
I'm new to the Oracle SOA Suite and have been creating very simple SCA WebServices (async and sync) prototypes to INSERT, UPDATE and Poll Oracle 9i and 11g databases. So far, everything works and passes the tests from EM.
I cannot get the Stored Procedure WebService to test successfully as I receive the error message below regardless of JNDI configuration for XA, non-XA, Last Logging Resource, Support Global Transactions,PlatformClassName, etc... The Outbound Connection Pool is setup correctly as the other DML tests have worked fine.
BINDING.JCA-12563
Exception occurred when binding was invoked.
Exception occurred during invocation of JCA binding: "JCA Binding execute of Reference operation 'dbReference' failed due to: Interaction processing error.

Check to ensure that the XML containing parameter data matches the parameter definitions in the XSD. This exception is considered not retriable, likely due to a modelling mistake.
The invoked JCA adapter raised a resource exception.
Please examine the above error message carefully to determine a resolution.

The SP SCA is the simplest possible application I can think of... The WebService accepts a single INT, calls BPEL>Receive>Assign>Invoke>dbAdapter(Stored Procedure) that accepts a single IN INTEGER parameter in an Oracle 11g database.
Steps I've used to create the SP SCA. (Create Empty SOA Application)
1.) Create Database Adapter in External References swim lane.
2.) Set JNDI and Connection.
3.) Browse to Oracle Procedure...click through Wizard and accept all defaults.
   CREATE OR REPLACE PROCEDURE TEST_SOA_API (
     wo_order_no_ IN INTEGER)
   IS
   BEGIN
     INSERT INTO TEST_TMP VALUES (wo_order_no_);
   END;
4.) WSDL, XSD, JCA are automatically generated.
5.) Create BPEL Process Component and select Template "Base on a WSDL". I choose the WSDL created from the Database Adapter wizard.
6.) The "Exposed Service" is automatically created and everything is wired.
7.) I deploy to my CompactDomain (running on a local Oracle12 db). No errors.
8.) I login to EM and Test the WebService..and ALWAYS receive the error message above.
I've tried BPEL Process and Mediator as components to simply pass the single incoming INT parameter to the SP DbAdapter and tried every combination I can think of with DataSource/DbAdapter Deployment through the Admin console. I used the same exact steps above for INSERT, UPDATE, Polling and have had no issues so I cannot figure out why I'm not receiving java.NullPointer exception or why I'm receiving the XML/XSD malformation error.
Stuck now...anyone have an idea what I'm doing wrong or simply tell me I'm an idiot and shouldn't do SP's this way?
FYI. I've turned on logging for the oracle.soa.adapter.db class to TRACE: 32(FINEST). Not much help to me

An even simpler request:
Can someone create an SCA that simply accepts a single INT parameter and calls a Stored Procedure (Oracle) that inserts this INT into a table? Maybe upload the project folder structure in a zip?
Seems someone with experience on this platform could execute this task in 10-15 minutes.
CREATE TABLE TEST_TMP (WO_ORDER_NO INT);
   CREATE OR REPLACE PROCEDURE TEST_SOA_API (
     wo_order_no_ IN INTEGER)

     INSERT INTO TEST_TMP VALUES (wo_order_no_);

SOAP Receiver Adapter Error in XI RWB - java.lang.NULLPointerException

Hi,
We have a asynchronous scenario in SAP-XI, where we are sending the PO data from SRM to third party (Hubspan / TNT). Proxy is being used at Sender side and SOAP Adapter is used for Receiver Communication Channel.
u2022SRM is sending around 1000 messages through background job and around 995 or 996 messages are being processed successfully and showing the proper XML payload as well in RWB. But 4-5 messages are getting failed in XI RWB for u2018java.lang.NullPointerExceptionu2019. For these failed messages we are not able to see the XML payload as well in XI RWB while these messages are showing successful status in MONI in SRM and XI and we are able to see the payload as well in MONI. The webservice is restarting and trying to send the payload three times in RWB, but it is getting the same Nullexception error.

u2022If we are resending the failed message from XI RWB, it is getting failed again with the same error. On the other hand if we are initiating the message again from SRM to Hubspan for the same PO, it is getting processed successfully in RWB but still not showing XML payload in RWB.
u2022If we are getting the payload from XI MONI for the failed message and doing a test with component monitoring in RWB, it is working fine.
Please help me to solve this issue.
Thanks
Sumit

Hi Sumit,
From my experience, when you transfer SAP POs through PI to external webservice, there should be some validation happens at the webservice layer of the target system before the web service passes the original information to their application layer. The validation can be anything like checking the Vendor address, Checking the correctness of the order ...etc etc . So i would suggest to ask your external web service folks to check if they have any validation in place before they pass the data to their application layer.
As you said only some POs/XMLs are failing, i strongly feel that this could be the issue.
Please note if you receive response code other than 200 from webservice, SOAP adapter treats that as error and send the same message back to AE.
Normally webservices won't send 200 code for any validation error
PS: you can still try to use XMLSpy to post the failed message to the web service to know the exact cause.

Java.lang.NullPointerException exception in SOAP Receiver adapter

Hi Experts,
I have a requirement where a third party system will call a service(WSDL) generated from ID to receive some details from SAP system.
The design and configuration part everything was created and was able to receive requests from third party system successfully till last week. But suddenly we are receiving the below error from today,
SOAP: call failed: java.lang.NullPointerException: while trying to invoke the method com.sap.aii.af.sdk.xi.mo.xmb.XMBMessageHeader.getMessageId() of an object loaded from local variable messageHeader
i went through some of the threads in SDN, but still we are receiving the same error.
Could any one can help me on this?
Thanks in advance.
Regards,
Govardhan Duvva.

Hi Duvva
Please check if there are any changes done on the web service side and double check the urls being used.
similar error is explained in the thread : Might be useful to refer once.

SOAP to IDOC scenario: java.lang.NullPointerException

Our trading partners currently post their xml files directly to our Integration Engine, where they are converted to idocs and posted to ECC. I am now trying to change this scenario to a SOAP to IDoc scenario so that we can process the files through the Adapter Engine using HTTPS. But I am running into an error when trying to post an xml file and I'm wondering what I am missing.
My SOAP communication channel is configured as follows:
Transport protocol: HTTP
Message protocol: SOAP 1.1
Adapter engine: Integration Server
HTTP Security Level: HTTP
Do Not Use Soap Envelope: *Checked*
Default interface and namespace have been specified
QoS: Exactly Once
If I post an xml file to this channel using the RWB test tool, I receive message java.lang.NullPointerException. However, I can find the message via the Message Monitoring in the RWB, with versions for both the AE and IE, each with status Successful. The idoc is created and successfully posted to ECC.
If I post this same file to the same URL using a third-party tool, I get the same error message along with more details (listed below). Futhermore, a message does *not* show up in the RWB and thus does not get converted to an idoc and posted to ECC.
Any ideas??? Thank you.

Help with "Exception in thread "Thread-4" java.lang.NullPointerException"

I am new to Java and I am trying a simple bouncing ball example from Stanford. Here is their simple example that works.

public class BouncingBallWorking extends GraphicsProgram {
/** sets diameter */
private static final int DIAM_BALL = 30;
/** amount y velocity is increased each cycle */

/** Animation delay or pause time between ball moves */
private static final int DELAY = 50;
/** Initial X and Y location ball*/
private static final double X_START = DIAM_BALL / 2;
private static final double Y_START = 100;
private static final double X_VEL = 3;
private static final double BOUNCE_REDUCE = 0.9;
private double xVel = X_VEL;
private double yVel = 0.0;
private GOval BallA;
public void run() {
setup(X_START,Y_START);
//         Simulation ends when ball goes off right hand
//         end of screen
while (BallA.getX() < getWidth()) {

yVel = - yVel * BOUNCE_REDUCE;
double diff = BallObject.getY() - (getHeight() - DIAM_BALL);
BallObject.move(0, -2 * diff);
} Now I am trying to modify "setup" so it I can create several balls. I made a simple modification to "setup" and now I am getting an error.

That is great! Thanks. I've got two question though.
1.) Now I want to have 100 bouncing balls. Is the best way to achieve this is through an array of GOvals? I haven't gotten to the lecture on arrays on Stanford's ITunesU site yet so I am not sure what is possible with what I know now.An array would work, or a List. But it doesn't matter much in this case.
2.) Are references being passed by value only applicable to Java or is that common to object-oriented programming? Also is there a way to force Java to pass in "BallA" instead of the value "null"?I can't say about all OO languages as a whole, but at least C++ can pass by reference.
And no, there's no way to pass a reference to the BallA variable, so the method would initialize it and it wouldn't be null anymore.
When you call the method with your BallA variable, the value of the variable is examined and it's passed to the method. So you can't pass the name of a variable where you'd want to store some object you created in the method.
But you don't need to either, so there's no harm done.

Urgent :-Need Help in DOtnet Dll integration with CFM 8. for error "java.lang.NullPointerException"

Hi Everyone,
I am trying to intergrate Dotnet DLL with coldfusion. The basic perpose of this DLL is putting value in cache.
My code is working fine on my local machine but it giving me problem on live server.
It is throwing "java.lang.NullPointerException" error.
Description of task:-
DLL:-
made in : Dotnet 3.0
Functions:-
setCache:- setting a string into cache.
getCache:- getting value from cache.
ClearCache:- Clearing all value from Cache.
Local Machine:-
OS: window server 2003
Coldfusion version :MX8
coldfusion Product level:-Developer
Result:-Task is working fine.No error what so ever.
Live server:-
OS: window server 2003
Coldfusion version :MX8
coldfusion Product level:-Standred
Result:-Task is throwing error "java.lang.NullPointerException"

Thanks for your response, but surely if the .NET Services was not running how can CF instantiate and dump the object with all the correct methods?
Anyway for some strange reason there is no Coldfusion .NET service in my services control panel even though I am running CF8. I have since downloaded the .NET service installer, run it and done a restart but I can still see no such service and the error continues?
I am running CF8 Dev on IIS 6 – Window XP pro and here is debug

Pretty much the same thing, Tomcat is the web server in CUCM, so that should have been sufficient.

Java.lang.NullPointerException with FTP receiver

Hi All,
I have a java.lang.NullPointerException in the Runtime Workbench for my FTP Adapter, that is a receiver.
At SXMB_MONI all the messages are successful.
What this could be?
Thanks in advance,
Daniela

Naveen,
Thanks for your help.
I took a look in RWB and it seems like there was an error when CC tried to connect with the FTP server. The last two messages are:
Success -> Connect to FTP server "10.112.144.108", directory "\interfaces2\conversionesTest"
Error -> Attempt to process file failed with Error occurred while connecting to the FTP server "10.112.144.108:22": java.lang.NullPointerException
Do you think ii could be an conection error (login, port) or a wrong configuration in my CC?
Thaks in advance,
Daniela Machado
