NullPointerException at AWS model instantiation.

Hi
I am trying to consume a third party web service in Web Dynpro using AWS model in NW7.0. But at runtime I am getting a NullPointerException at the very first line where I instantiated the model object. Line of code where the exception is thrown is QasWsModel qasModel= new QasWsModel(); where QasWsModel is the model name. It would be really helpful if you can give some clue on this.
Thanks & regards
Sudip

Hi,
Try deleting the existing Model from the "Models" section of your project. Then recreate the Model using the AWS Wizard. That should clear out the problem. If it doesn't then the model is not beinf created correctly in the AWS.
Try navigating to the exact name of the java file for the Model in the "Navigator" view.
If the Model java file name is accurate then there is probably an issue with the source of the Web Service Implementation. This would mean that you would have to regenerate the WSDL file to ensure that there were no issues.
Hope that helps.
Thanks.

Problem in using AWS model for PI interface

Hi
We want to consume XI inbound interface for a 3rd party web service in web dynpro via AWS model; we can create the model class from the wsdl file imported from PI interface; but facing some issue in configuring the logical destination as we don't have any wsdl url from PI which we can use in the dynamic proxy configuration.
Thanks in advance.

Problem with model instantiation

I have an EJB model and while instantiating it in WDP I am getting an error at runtime:
The initial exception that caused the request to fail, was:
java.lang.NullPointerException
at -- Optimized, preallocated exception. No stack trace. Run VM with -XX:-OmitStackTraceInFastThrow to avoid this optimization. -- .()
I cant make any head and tail out of this. There is absolutely nothing in stackTrace other than the above message. I could instantiate my other EJB models and they are working fine. I dont know why this one particular model is giving some problems...
I tried reimporting/rebuilding/reload but in vain. My WS (which encapsulates EJB) is working fine.
Please help!!!

The compiler does not generate template instances that are already in libCstd, which is linked by default to programs. Instead of trying to force those instances into your shared library, you should build your library with a dependency on libCstd.
Remember that no system libraries are referenced automatically when you create a shared library -- you have to mention them explicitly. Normally you want to link against libCstd, libCrun, libm and libc. Refer to the C++ User's Guide that comes with the compiler, the "Building Libraries" chapter.

Consuming AWS model in webdynpro java application

Hi,
We are using the following environment.
SAP Netweaver Portal 7.3
Netweaver Developer Studio 7.3.
We have imported a AWS webservice model in a webdynpro application. When we deploy the application in portal, we are receiving the following runtime error,
error in executing the model: Illegal model class renaming: Model classes with QNames '/definitions/types/xsd:schema[5]/xsd:element[15]/xsd:complexType' and '/definitions/types/xsd:schema[5]/xsd:element[15]/xsd:complexType#Choice1' were both renamed to the same name 'com.sap.demo.harmanmdmui.wd.models.addresswebservice.RunBatchJobRequest'
Addresswebservice is the webservice name and harmanmdmui is the application name.
Pleaae advise me with a probable solution.

Java.lang.NullPointerException while reimporting model

Hi All,
I have a Web Dynpro project that contains several models.

Hi Timo.
Following are the answers.
Which jdev version? --- 11.1.1.3.0
Which kind of application? ---- It is a simple ADF fusion application.
What Other systems your application talks to? --- Application is having DB as Oracle & Weblogic server, doesnt talk to any other systems.
Which kind of security do you use? --- JAAS security.
I have a login page. After entering the UID & PWD, it gets verified against JAAS. If it is a valid user it displays the Screen with all the records for that User.
Problem is when i Click on the Login button, it tries to do something for a second & after a while it displays this exception on the screen.
My Local server is a Windows server, while this same application works fine when deployed to a Unix Server. I checked all the configuration on both the servers, didnt get anything that makes any difference.
Pls Help.
Thanks.

NullPointerException on polymorphic model registration

Not too off topic, I saw in an earlier post (Re: Polymorphism and DPL that someone had problems persisting their polymorphic subclasses via a single method. I solved that using a visitor pattern:
public interface Node {
public abstract void accept(Visitor visitor);
public class Tree {
private final Visitor putVisitor = new Visitor() {
    public void visit(Leaf leaf) {
        leafsById.put(leaf);
    public void visit(Branch branch) {
        branchesById.put(branch);
    public void visit(Root root) {
        rootsById.put(root);
public void doTheThing(Node node) {
    node.accept(putVisitor);

Hi Tony,
The problem turned out to be
SecondaryKey(relatedEntity = My@PersistentInterface)Right. A relatedEntity must be an entity class. Interfaces may not be @Persistent or @Entity.
Sorry about the NPE, you should get a more meaningful exception when trying to make an interface @Persistent. I'll fix that and also clarify it in the javadoc.
It would be really nice with @PrimaryKey at
method-level.Methods are not used to define persistence in the DPL for a couple reasons:
1) Simplicity. Only fields are persistent, which is a simple rule. However, it is limiting. For example, you can't have a computed secondary key or a secondary key field nested in a sub-object, except by adding a redundant field in the @Entity class. For now, I suggest using the redundant field approach.
2) Performance. A key design goal for DPL is to avoid un-marshaling entities in the middle of JE read and write operations, in order to extract secondary keys from entity data. DPL stores secondary key values at the front of the record data, so extracting the value is very fast and does not require a full un-marshal. However, perhaps key values returned by annotated methods could be stored redundantly at the front of the record. Or if that isn't feasible, we simply say that you pay a performance penalty for using methods rather than fields to define persistence. More design work is needed, but it is probably feasible.
For now I'm going to put this aside and list it as something to consider in the future as a DPL enhancement. Please don't expect this to be added soon, but we will be thinking about it.

Difference between webservices model and adaptive webservices model

hi
Can any one explain me regarding Difference between webservices model and adaptive webservices model.
Thanks

Hi,
In old WS Model, ithere was no concept of logical destinations.
There if you are using a WSDL located on a server and if the location of the WSDL
changes, your application won't run. The deployed application using the WS Model will have trouble finding
the WSDL. As a result you'll have to again import the
model. Moreover old WS Model does not have re-import functionality.
But incase of AWS Model, you can desine logical destinations and even if the location of the WSDL changes, all you have to do is change the new url in the Visual Admin and not import the model again.
You can visit the following link for more details:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b04308ed-62d5-2910-b3a6-c26771b1c78e

Probelm setting up Adaptive Web Service model

I am having a problem setting up AWS using the wizard. The WDSL file I need to go to requires user id and password. While viewing it on IE is not a problem because IE passes my integrated Windows credential over behind the scene, it fails while I am trying to create an AWS model from this WDSL URL.
After I enter the WDSL URL, the AWS wizard prompts me for user id and password for the destination server. I put in my id and password but it will not take it. I tried entering my id with and without the domain name but none of them works. In the log, I got the follwoing error message. Does anyone encounter this problem before?
I don't have problem creating an AWS for web sevrice that does not require user id/password.
Caused by: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized. The requested URL was:"http://hostname/thewebservice.asmx?WSDL"
     at com.sap.engine.services.webservices.tools.WSDLDownloadResolver.resolveEntity(WSDLDownloadResolver.java:201)
     at com.sap.engine.services.webservices.tools.WSDLDownloadResolver.resolveEntity(WSDLDownloadResolver.java:188)

     at com.sap.engine.services.webservices.espbase.wsdl.WSDLLoader.loadDOMDocument(WSDLLoader.java:127)
Thanks.

Hi Robert
The error says "Unauthorized". Maybe the user/password does not have an appropriate permission to access the WSDL resource.
Additionally, as I remember, the Import wizard optionally supports import from local WSDL files. So you can download WSDL in IE, store it locally and pass to the wizard. To download WSDL try to add parameter u201C&zipu201D to the WSDL URL:
http://hostname/thewebservice.asmx?WSDL&zip
Another way to download WSDL is NWA -> SOA Management -> Application and Scenario Communication -> Single Service Administration, but you must know credentials for NetWeaver Administrator on the remote Web service provider system.

Shared Node Model not created

I have created multiple task flows and created the adf menu models. I have created the views for all the nodes and have created shared nodes for the lower level task flows. I have verified that the managed beans are all present for each task flow and they are located in the appropriate menu models XML file and referenced in the root_menu.
When I run the page I get the following error: java.lang.NullPointerException: Shared Node Model not created for query_menu. Check for the existence of the corresponding managed bean in your config files.
I did find another post related to this problem, but did not understand the post.
They suggested looking at the following:
"The file that should contain the menu bean is the file specified in the service-level property "Service Adfc Config". Can you check whether this property has a valid value? Also, make sure the advanced service-level checkbox property "generate ADFc Config Files?" is checked."
Where do I locate the service-level property "Service Adfc Config"? I have been looking through all the config files in the application and the preferences in JDeveloper.
I am new to JDeveloper and ADF.
Thank you for your help.
Chris

Hi,
It makes perfect sense that menu_root.xml has a reference to the managed bean #{JhsMigrateModuleMenu}.
This bean should be defined in the adfc-config for your appmodule, probably /WEB-INF/adfc-config-jhsmigratemodule.xml
It looks like this (with different names):

<managed-bean>
<managed-bean-name>AppModuleMenu</managed-bean-name>
<managed-bean-class>oracle.jheadstart.controller.jsf.bean.JhsXMLMenuModel</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>source</property-name>
<property-class>java.lang.String</property-class>
<value>/WEB-INF/menu-appmodule.xml</value>
</managed-property>
</managed-bean>

I guess that this definition is missing or has the wrong name or something. Perhaps it is pointing to an invalid XML menu model file (in my case /WEB-INF/menu-appmodule.xml)
Can you post your findings here?

Workshop CRASHED while editing a page flow

Workshop Gurus -
Any clues on this bug. I get this error while editing pageflow. It just started
happening this morning.
I must say, WLW crashes gracefully. It allows me to report this message directly
to BEA, and then allows me to save my files. However, I do need a resolution to
this problem, hopefully soon.

Raj -
Yes I am using SP2. I have had Workshop crash SEVERAL times when working with
page flows. Some sort of null pointer exception. The only good thing is that workshop
crashes gracefully, so I didn't lose any work that I was doing.
Thanks.

JBO-25017 Sporadic error during AM passivation/activation

As I said in the other thread, I have found one nasty error that happens sporadically and cannot be reproduced in production environment.
But with disabling AM pooling during the stress test I can see this error:
JBO-29000: Unexpected exception caught: oracle.jbo.RowCreateException, msg=JBO-25017: Error while creating a new entity row for MailOut.
JBO-25017: Error while creating a new entity row for MailOut.
java.lang.NullPointerException
Here is how I create the new record. Say on a page A there is a link "NEW" which takes user to data entry page B.
before the page B renders, it calls AM exposed method
<invokeAction id="prepareSentMail" Binds="prepareToCreateNewSentMail"
             Refresh="prepareModel"
             RefreshCondition="${adfFacesContext.postback == false}"/>
<methodAction id="prepareToCreateNewSentMail"
                  InstanceName="TrackingService.dataProvider"
                  DataControl="TrackingService"
                  MethodName="prepareToCreateNewSentMail"
                  RequiresUpdateModel="true" Action="999">
      <NamedData NDName="studyId" NDValue="${sessionScope.studyId}"
                 NDType="java.lang.String"/>
      <NamedData NDName="individualId" NDValue="${sessionScope.individualId}"
                 NDType="java.lang.String"/>
    </methodAction>So page calls prepareToCreateNewSentMail AM method:
    public void prepareToCreateNewSentMail(String studyId, String individualId) {
        ViewObject vo = getSentMail();
        vo.clearCache();
        //removeAnyInvalidNewSentMail();
        //vo.setMaxFetchSize(0);
        //vo.executeQuery();
        //vo.setWhereClause(null);
        //vo.setWhereClauseParams(null);
        Row newRow = vo.createRow(); //<-- CRASHES HERE!!!
        vo.insertRow(newRow);
        newRow.setNewRowState(Row.STATUS_INITIALIZED);
        vo.setCurrentRow(newRow);
        String studyPhaseId = JSFUtils.getFromSession("studyPhaseId").toString();
        newRow.setAttribute("StudyPhaseId", studyPhaseId);
        String studyPhaseOrder = JSFUtils.getFromSession("studyPhaseOrder").toString();
        this.getStudyPhasesUntilCurrent().prepareStudyPhasesDropDownList(studyId,studyPhaseOrder);
        newRow.setAttribute("StudyId",studyId);
        newRow.setAttribute("IndividualId",individualId);
        newRow.setAttribute("HowSentId","REG");
        newRow.setAttribute("DateSent",new Date(Date.getCurrentDate()));
    }And so the error shows @ Row newRow = vo.createRow(); line
I will post later when(if) I make progress

I have modified the code as:
public void prepareToCreateNewSentMail(String studyId, String individualId) {
//..... code from above goes here
        try {
            Row newRow = vo.createRow(); // THIS IS LINE 424
            vo.insertRow(newRow);
            newRow.setNewRowState(Row.STATUS_INITIALIZED);
            vo.setCurrentRow(newRow);
         //the rest of the code goes here
        catch (Exception e){
            e.printStackTrace();
}and here is the printout:

Consuming 3rd party web service in Java web dynpro application

Hi All,
I am working on a scenario where external(3rd party) web service has to be consumed in WD Java application. I am provided with WSDL file. Let me explain how I usually consume other webservices:
     Create model->AWS model->Remote Location/file System->provide url->create/choose service group->finish
     Then I would generate the code in custom controller by applying template
      I assign provider system as local for the service group in nwa.
This is normal process to me. I am struck with this 3rd party web service. Please share your ideas on the same. Any help is highly appreciated.
BR,
Manoj

I ve created a provider system pointing to where 3rd party WS resides. i am trying to connect through WSIL. While pinging that provider system, I don't see that particular WS(that I am gonna consume). And while assigning this Provider system to service group, processing state getting 'Failed'.
What could be reason?

NullPointerException at AWS model instantiation.
