Problem in executing the external webservice in a web dynpro java

Hi,
I have imported the Adaptive Web Service Model in web dynpro application and while executing the model, I am receiving the following error,
Exception when retrieving the WS invoker using the execution destination
I have tested the webservice in ws navigator which works fine.
I have defined the destinations under destination management template of SOA.
If anyone has encountered and solved this problem, please advise.
Thanks,
Appachi

Hi Robin,
Yes I have defined the stack trace and have defined the system & host name in configuring the destinations.
Yes, I have given HTTP authentication to webservice.
Advise me if anymore configurations have to be done.
Thanks,
Appachi

Problem when generating an non-interactive form in Web Dynpro java.

Hi,
I'm trying to create a PDFDocument using a creation context in java. Everything works fine when the Interactive property of the creation context is set to true. When I change it to false however, the Web dynpro application hangs and eventually throws the following exception:
java.net.SocketTimeoutException: Read timed out
   at java.net.SocketInputStream.socketRead0(Native Method)
   at java.net.SocketInputStream.read(SocketInputStream.java:129)
   at java.io.BufferedInputStream.fill(BufferedInputStream.java:183)
   at java.io.BufferedInputStream.read(BufferedInputStream.java:201)
   at com.sap.engine.services.webservices.jaxm.soap.HTTPSocket.readLine(HTTPSocket.java:806)
I'm wondering why this exception occurs when i'm generating a non interactive form and never appears when i'm generating a form with the Interactive property set to true.
Any ideas?
Edited by: Arjan Nieuwenhuizen on Feb 25, 2008 3:24 PM

Yeah I know changing the form properties will solve my problem, but since i'm developing a training for Interactive Forms in Web Dynpro Java, I wanted to figure out why the (static / non-interactive) combination didn't work, turned out to be a template problem, which i still didn't figure out, except the fact that having flowed content on your template is not the problem.
My ideas about your question:
When we have the layout of an Interactive Form, its clear if it's meant to be static or dynamic, we don't know however, if it's interactive or non-interactive.
I don't think we can judge a layout to have an Interactive or non-interactive purpose, can depend on the situation in which the same form is shown/used:
- One moment it can be interactive, e.g. user is filling in the form, can enter data etc.
- Next moment it can be non-interactive, e.g. form is shown to another user.
So it's more the scenario/situation that determines if the form is interactive or non-interactive.

Kill the RFC connection as soon as the call is completed in Web Dynpro JAVA

Hi Experts,
Please guide us how to kill the RFC Connection from web dynpro java as soon as the execution is completed.The FM connection (Adaptive RFC) isnt getting closed in IS-U side. Please guide us how to close them explicitly.
We are getting the following error
(102) RFC_ERROR_COMMUNICATION max number of cpic clients exceeded (300)

hi suvankar ,
wdContext.current<Modelname>_InputElement().modelObject().modelInstance().disconnectIfAlive();
use this option after executing your rfc, it will remove the connection to the r/3.
adn this
(102) RFC_ERROR_COMMUNICATION max number of cpic clients exceeded (300) -- is occuring because the pool size defined the jco destination is not sufficient, ask your basis team to increase the pool size.

Tutorial The concept of componentization in web dynpro java...

Hello there,
I try to complete this tutorial but i have a problem, maybe this tutorial is a little bit incomplete.
in page 18 have a code with this line:
pUsage.createComponent(wdContext.currentSelectedPersonElement().getPerson());
but in my app there aren't this code: wdContext.currentSelectedPersonElement().
I believe, this Element i need to declare in a Context Attribute of RootComponent.
In the Page 19 there something like the above situation:
The value of selectedKey of RadioButton is SelectedPerson.Person, probably this value is an attribute mapping to the SelectedPerson.Person of RootComponent.
In the tutorial, don't have how declare this attribute and i don't now how declare it.
Can anyone help me.

Problem while executing the transaction code FMBV (Reconstruct)

We are facing a problem while executing the transaction code FMBV
(Reconstruct Availability Control in Funds Management) in it when we
execute this transaction system only updates the expenditure which is
made before technical upgrade from 4.6c to ECC6 EHP6, against the
Assigned Budget (KBFC budget type) in the Annual Budget Table (BPJA)
and
the expenditure which we made after the upgrade, the program just
ignore
it. We can also see the expenditure in the standard FBL3N report.
Please guide us.
Thanks and Best Regards,

Dear Abrar
In your description, you refer to missing update after an upgrade. First of all, see if table FMIT is consistent, as it is the basis for calculating the assigned values during AVC reconstruction.
Refer to this note:
977016 FMIT: Missing totals records in Funds Management And perform following steps:
1.- Run program RGZZGLUX
2.- Run program RFFMRC04 to match totals table with line items. A test run after a successful effective run should not find inconsistencies.
3.- If RFFMRC04 does not show more inconsistencies, run FMBV as final step.
Note that this reconstruction must be done without any other budgeting/posting activities at the same time, otherwise you may cause other inconsistencies.
Please let me know the results.
Best regards,
977016 - FMIT: Missing totals records in Funds Management
Symptom
After the upgrade to ERP 2004 or higher you realize that the FMIT totals table is no longer updated in Funds Management. You start the RFFMRC04 report to reconstruct the totals, but the report still displays the missing totals after an update run.
Other Terms
FMIT, EA-PS, ECC 5.00, ECC 6.00, ECC 7.00
Reason and Prerequisites
This problem occurs due to a generation error.
Solution
Start the RGZZGLUX report to generate missing source code in FI-SL. Then start the RFFMRC04 report to reconstruct the totals, now another run of the report should no longer display any errors.

Problem in completing the TASK when using Web Dynpro Java and BPM

Hi,
I am using Web Dynpro Java and BPM.
i see my Web Dynpro View when i run the process.
Just that the task is not completing.
when i click on the Web Dynpro button to signal the completion of the event, nothing happens.
i have appropriately created events in both Component controller and Interface Controller and used the same in creating the Task.
a method in Component controller fires the event and a button click in the view calls this method.
i have successfully completed Donka Dimitrova's "SAP Netweaver Business Process Management-End-to-End Process Implementation Sample " but when i tried my own with slight modifications, it is not working !!!

Hi Amol,
The way you described the things, I dont see any problems. Just to make sure that you are triggering the right event that you mapped as completion event for the task, try to cross check once again and see if the correct event is getting triggered. Also try to put some messages for debugging to see till where the control goes.

Consuming External Web Services in Web Dynpro Java

Hi All,
I an trying to consume external web service in Web dynpro java using Adaptive Web Service Model.
But getting below mentioned error while executing the web service
Exception on execution of web service with WSDL URL 'D:\Web Service Project\CurrencyConvertor.asmx.xml' with operation 'ConversionRate' in interface 'CurrencyConvertorSoap'
Steps i followed are as below:

In next step i select No logical destination radio button and click on next
In next step, browse the WSDL file and successfully import the WSDL file.
2. After successfully importing the WSDL file i wrote below code in Init method:
WebModel modelweb = new WebModel();
Request_ConversionRate reqConversion = new Request_ConversionRate(modelweb);
ConversionRate conversion= new ConversionRate(modelweb);
reqConversion.setConversionRate(conversion);
wdContext.nodeRequest_ConversionRate().bind(reqConversion);
3.After that execute the model - code is given below :
    IWDMessageManager manager = wdComponentAPI.getMessageManager();
    try
      wdContext.currentRequest_ConversionRateElement().modelObject().execute();
      wdContext.nodeResponse().invalidate();
      wdContext.nodeConversionRateResponse().invalidate();
    catch(Exception e)
      manager.reportException(e.getMessage(), false);
Please let me know how to resolve this.
Thanks
Sandy

Hi,
You need to use destinations for metadata and modeldata.
Configure those destination in Visula admin.
you can refer to following link.

Deploying problem of web dynpro java application

Hi,
Since the exception says "Are all referenced components deployed and available on the engine?"
Check wether any DC is used as a used DC in the webdynpro component which you are deploying.
If any used DC is available try to deploy that DC in the server and then deploy ur webdynpro application.
If all reference DC's are avialable in server, still if you get this error try to rename the component and reload+rebuild the project and deploy it.
Hope this helps you...

Problem with Table display in Adobe Form of Web Dynpro ABAP

Hi Team,
I'm trying to display a table in Adobe Print Form (not interactive). The table is bound to the context node in the Web Dynpro ABAP where the cardinality is 0:N. I get a short dump. Don't know what to do here. I'm able to display individual fields from my context successfully. Looks like something is missing when I try to display a table. Any pointers to display a data table in Adobe? Any step by step example you know of where I can find out what I did wrong? Many thanks for your time
We are on support pack SP06 on 2004S release.
DUMP INFORMATION:
Short text
    Access via 'NULL' object reference not possible.
What happened?
    Error in the ABAP Application Program The current ABAP program "CL_WD_ADOBE_SERVICES==========CP" had to be terminated because it has come across a statement that unfortunately cannot be executed.
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not caught in procedure "CREATE_PDF" "(METHOD)", nor was it propagated by a RAISING clause.

Hi Thomas,
We upgraded our system(2004S) to SP10 so that we can use the ADOBE form printing in Web Dynpro ABAP but could not apply note 1034425 because of the validity constraints in SNOTE. All the pre-requisite notes are already in the system apart from one note 1029721 which talks about supporting input helps. We don't want to use input helps in our system and cannot upgrade to SP11 because of problems with Business functionality.
Questions:
1) Is note 1034425 absolutely dependent on 1029721?
2) If NOT, can someone please correct the validity so that we can implement using SNOTE.
3) Would it be OK if we manually apply the changes specified in 1034425 without implementing 1029721?
4) If all of the above is not applicable, is there any other note which fixes the above mentioned short dump.
Your help in this matter will greatly help us in using the ADOBE services provided by SAP WDA.
Thanks much

Problem of refreshing a tree in web dynpro java

hi all,
I'm facing a problem for refreshing a tree in web dynpro java for SAP HR.
I created a viewset with 2 cells( 1 view for each).
In the 1st view I created a droplistbyindex to select the unit ID and in the 2nd view ( defaut=false) I called a method to populate my tree according to my selection in the 1st view ( method called in wdInit).
When I make the first selection everything is ok.
But when I select another unit ID, the tree is not changed and I know the context is well changed according to my selection.
So I think the method is executed only the first the view is called.
In this case, how can I refresh my tree on real-time?
Thanks for your help
Yimin

May be u can write the code wdDoModify instead.

Hello John,
Thanks for the link. We have performed the steps in this blog:
1) Create DC Project "External Library" with name js/jars:
- Add *.jars in folder Libraries.[Screenshot Libraries|http://img846.imageshack.us/img846/8395/jsjars.jpg]
- Add archives (*.jar) to public part with name ExternalLib. Which option to choose?
a- Provides an API for developing/compiling other DCs (Option chosen)
b- Can be packaged into other build results (eg SDAs)
- Development Component -> Build
Step 1 is OK.
2) Create "J2EE Server Component / Library" DC with name js/lib:
- Add Used DC -> public part project ExternalLibrary -> "ExternalLib"
- Specify both build time and run-time dependency here and strong.
- Generated SDA file in <var>gen/default/deploy</var> How do we check that it contains <var>js.jar</var>?
- folder gen/default/plublic/defLib/lib/java then you meet *.jars files again. is OK.
- Development Component -> Deploy.
- Go to Visual Administrator. We found the library js/lib, but has no associated *. jar. It is the problem.[Screenshot Visual Administrator|http://img542.imageshack.us/img542/5537/visualadminlib.jpg]
3) Create "WebDynpro" DC with name pdf_jasper
- Add used DC (defLib) to WebDynpro DC with option "Build time".
- WebDynpro References -> Library references --> add <var>jslib
- Deploy
- Run error: java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource

Hi,
1) in Development Infrastructure Perspective -> rightklick in Navigator/Projekt Explorer -> new Project -> (Development Infrastructure) Development Component (DC).
NWDS generates Project Ressources e.g. the folder "libraries"
2) copy the jars to the "libraries" folder.
3) rightklick on the newly created Development Component (DC) -> Development Component -> Show In -> Development Properties -> go to the Tab "Public Parts",
in -> "Defined Public Parts" -> klick on Button "Add" -> give a name for "Public Part" -> at "Purpose" select "Compilation" -> Finish.
rightklick on the newly created Public Parts -> select "Manage Entities" and select the jars you want to use -> Next -> Finish.
4) switch to the Mobile Apps for Handhelds Perspective -> in Development Component select e.g. the Service Component or the UI Component ->
rightklick -> Development Component -> Show In -> Development Properties -> got to Tab "Dependencies" -> klick on Button "Add" -> under the Node MyComponents -> select the newly created Development Component with the Public Parts/jars (that was created in 1 - 3).
thats all, now you can deploy your application

How to find a BADI to change the default value of a Web Dynpro Screen?

Hello Experts!!
My requirement is as follows-
The SAP cProjects Distribution Functions screens default the Calculation Base to Per Day(This is represented via the initially-selected value in a listbox). The requirement is to make it deafult to the current standard Per Month (This also appears in the list box).
Is there any BADI to achieve this?
I tried putting a debug point in the Get_Instance method of the class cl_exithandler to find all the BADIs associated with the screen. I got a bunch of BADIs with no luck. And now I am not even able to debug anymore as the debuger is not opening. Can anybody tell me why this is happening? It was working two days before. And yes I have read all the posts about debugging a web dynpro application and I am doing everything that is mentioned there- I have set an external debug point and I have checked the "IP Matching" checkbox against my name in the workbench, but, with no luck
Any help on this will be greatly appreciated.
Thanks and Regards,
Smitha

You can't do this on a running VI. If you have an idle VI, you can open a reference to that VI and use an invoke node with the Make Current Values Default method, but that will only work in LV (i.e. not in an EXE) and will affect all the controls. What you can do is save the values to a file and load them when the program starts. OpenG's File I/O package includes some VIs which will help you with that.
