Exceptions in Webdynpro's generated methods

Hi,
I'm trying to develop a WebDynpro component and I'm using its feature to generate actions and methods. How can I generate a method, which throws an exception?
any added code outside the //@@begin and //@@end will be deleted by the generator....
regards,
Martin

As the views part deals with the creation of user Interface you are supposed to handle the exceptions here.
i.e
Create the methods with functionality in you rmodel and handle its exception in the view.
Perhaps if you can explain the requirement that drives you to create the method that is supposed to throw an exception, we can help.

BPM error: exception cx_merge_split occured,object FLOWITEM method EXECUTE

Hi Guys
I am working on a interface involving BPM.....
I am facing this problem while executing the interface...
I am getting error texts as below:
exception cx_merge_split occured,
object FLOWITEM method EXECUTE
I am trying to fix it....Please provide any iputs on this...
Thanx in adavance.

Is your Transformation step designed for multimapping (n:1 or 1:n)?
If yes the payload seems to be incorrect....did you check the working of your mapping (MM/ IM) using the expected payload structure...
the transformation step in BPM has been given exception as System Error
There is one block step before the transformation step...in which exception is not given...?can this be the cause??
Does it mean...you have a Block step in your BPM and your Transformation Step is placed in it....the Block should have an exception handling branch...have the exception handling logic as per your need....the Block step needs to use Exception Handler...same Handler to be used in the Transformation Step's System Error section.
Press F7 and check if your BPM is giving any warning message.

Abhishek.

How to handle exception thrown in standard bo method in the workflow design

Hi Experts
    how to handle exception thrown from standard bo method in the workflow design. For example, bo BUS2032, METHOD confirm. If the user cancel it, it will throw exception. In the workflow, how to catch this exception and add corresponding steps in the workflow.

@jrockman li
Try to implement the logic that what ever you are performing in the BO mehtod in a FM and in the FM you have tab with name EXECPTIONS define the execption in that tab.Now in the BO method you call this FM and if the exception occurs by using RAISE you can raise the exception in the FM and based on the number of exceptions your sy-subrc value will be set
so when sys-subrc is not eq 0 then pass a value back t the workflow container., I think this will work.
a sample Snippet for understanding purpose
CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
    filename         = <path>
    filetype         = 'ASC'
IMPORTING
    filelength       = lv_len
TABLES
    data_tab         = l_txt_tab
EXCEPTIONS
    file_write_error = 1          " If this Exception occurs
    invalid_type     = 2
    no_authority     = 3
    unknown_error    = 4
    OTHERS           = 10.
CASE sy-subrc.
WHEN 1. " SY-SUBRC value will be 1 then,
      " Pass or set the value back to the workflow conatiner element
ENDCASE.

Which exception is thrown in overidding method

Hi ,
I have a doubt in doubt in overriding method. What type of exception is thrown in overidding method.

Hi all,
I have a doubt.. I read some where that an overriding
method can throw a different exception from the
orignal one. Does that exception has a restriction
that ..it shouldn't be more Generic than that of the
original?
Yes, this is what the jls in section 8.4.4 has to say about throws and overriding
A method that overrides or hides another method (�8.4.6), including methods that implement abstract methods defined in interfaces,
may not be declared to throw more checked exceptions than the overridden or hidden method.
More precisely, suppose that B is a class or interface, and A is a superclass or
superinterface of B, and a method declaration n in B overrides or hides a
method declaration m in A. If n has a throws clause that mentions any checked
exception types, then m must have a throws clause, and for every checked
exception type listed in the throws clause of n, that same exception class or one
of its superclasses must occur in the throws clause of m; otherwise, a compile-time error occursLets take an example
public class A
   public void meth() throws IOException
        //some code that throws IOException
class B extends A
   //this is ok bcos FNFException inherits from IOException
   public void meth() throws FileNotFoundException
      //code that throws FNFException
   /* THIS WILL FAIL TO COMPILE
   public void meth() throws Exception
      //code that throws FNFException
I think the access modifier in the over riden method
can't be more restrictive than the original one.. For
example..The overriden method can change the access
modifier from default to protected..But not vice
versa..correct.
Cheers,
ram.

2007A: Exception handling for new ProjectService methods

Normally for other objects the Add() method returns error code and calling the GetLastError you get the description.
AddProject(Project) method of ProjectService returns ProjectParams object.
So the question is where to get the error code or what is the correct exception handling for that new methods in 2006 SDK.
Thanks for any help.
Tomas

Hi Thomas,
For DI API services there is no return code as for the basic objects methods like Add, Update,...
The only way is then to put try/catch blocks in your code and identify the error message with the Exception.Message property (same mechanism as we have for the UI API). No way to filter them by return code.

How to handle method based exceptions in webdynpro abap?

Hi ,
    I want to raise an exception from my method.....I am doing division operation inside my method...when I am entering a very large amount , that time I am getting run time error.....please someone help me to catch this exception and display on browser.
Thanks & Regards
Suman Kumar

Hi Suman,
You can catch the arithmetic exception by using exception class CX_SY_ARITHMETIC_ERROR as below
Sample code:
          data lv_ex_msg               type string.
          data lx_sy_error              type ref to CX_SY_ARITHMETIC_ERROR.
          try.
               "here goes your code
          catch CX_SY_ARITHMETIC_ERROR into lx_sy_error.
                           " you can get exception text as below
                         lv_ex_msg = lx_sy_error->get_text( ).
                         or
                     " lv_ex_msg = lx_sy_error->get_longtext( ).
          endry.
Hope this helps you.

Webservice Exception from Webdynpro

Hi,
We are on 7.1 SP04 Patch 1. We have created a webservice with http and None Authentication and deployed on EP 7.0 server. We have set a constant User Name and Password in Visual Admin.
We are able to execute this webservice successfully from Webservice navigator.
We have developed a Webdynpro appln with this webservice. We are getting an exception when the webservice is getting executed from Webdynpro appln.
"Exception on execution of webservice with WSDL url '<wsdl url>' with operation 'webservice name' in interface"
We checked in the trace file and got the following message
com.sap.mdm.logging.MdmLogger warning
WARNING: PingServerCommand failed
Have any one faced this issue?
Thanks,
Arun prabhu

Hi Walter,
The webservices are developed using MDM Webservice generator. The webdnpro application has to access MDM Data using MDM Webservices / MDM Java APIs.
This was working fine with MDM 7.1 SP03. Now we have upgraded to MDM 7.1 SP04.
When I try to access MDM Data from webdynpro using MDM Java API commands, I am getting an exception at AuthenticateUserSession Command. While access using MDM Webservices, I am getting an webservice exception and an entry in trace file.
Thanks,

Exception while exposing Application Module Methods as Web Service

Hello Everyone,
I am working on Jdeveloper 11.1.1.3.0 version and tried to expose one method of application module as web service. To do this, i used "Service Interface" tab of Application module within Jdeveloper and Jdeveloper had generated all interfaces, stubs, code for the Session bean required for web service. I am now trying to "Test Web Service" from the implementation class generated then i am getting this error in Weblogic deployment. Any help/pointers would be highly appreciated.
I used another installation of Jdeveloper same version at my collegues desktop but getting the same error. Not sure, if this version of Jdeveloper is having issue in exposing application module as web service. I think that database related exception can be ignored as no database call is being made by the application.

XI Webservice Exception within Webdynpro component

Hi All,
I have created a model for an XI webservice within the webdynpro project and created 2 view one for search and the other for search results and have accordingly associated the context variables of these views to the import and response parameters of the web service.
Now when I execute the method associated with this service I receive a service exception as enclosed below :
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized
Can someone please tell me if there any settings to be done on the client or server settings.
Thanks in advance.

Getting nullpointer Exception in Webdynpro application.

hi All,
I am getting one NullPointerException in the screen, .
This message is only coming only when the form is loading first time. So when i put the debugg statments to trace the error where it is coming, i come to know that it is coming before calling the init() method.
So when i click on the any of the button or firing the event in the screen, , i am not getting that error in the screen. Can u please tell me anybody , what would be the problem.s
for your reference i have added that screen shot in the in the following path. Please look at the same. It is production. i am not able to find the problem, could any body help to find what is the problem.
My Home > Web Dynpro Java > Main > Attachments
file name is > NullPointerException Easy.GIF
Is this error coming any of the life cycle methods creating internally by webdynpro framework.?
What is the lifecycle process of the webdynpro application.
Regards
Vijay

Hi Luciano ,
thanks for the reply
I have put the debugg statments also in the component contoller and custom controller init methods.
After that when i run the application it is throwing the exception in the component controller inbetween init() and wdDoBeforeNavigation() methods.
For your reference i have attached screen shot in the following path. under wiki
My Home > Web Dynpro Java > Main > Attachments
Filename is > NullPointerException Easy1.GIF
Acutally i was not able to provide the stract trace bcz , when i went the log files i am not finding any exception or error.

NWDS Webdynpro Code Generator overwrites custom source with old fragements

Hello,
I am developing Web Dynpro Components in Java with NWDS 7.1. and I am experiencing a strange behavoiur of the code generator. After I save the changes I made to a View in the "View Editor" the View is rebuild and the corresponding Java Source Code gets overwritten with an older version of it.
The same thing happens after editing the model or context bindings of the view controller, except that in this case all Java Sources are rebuild and overwritten. Its not that all method implementations are deleted, itu2019s the matter that they are replaced by older versions.
As a developer I think thatu2019s very dangerous, because sometimes I don't recognize which code areas are rewritten by designtime - I get Null Pointer Exu2019s by runtime.
Does anyone of you have an advice for me how to avoid these problems? Does anyone of you experienced the same behaviour before?
Thanks in advance!
Kind regards
Andreas Horn

Your question is not NWDI related. Post it in the [Web Dynpro for Java|Web Dynpro Java; forum or the [Java EE 5 @ SAP forum|Java Development;.

NO_PERMISSION Exception when calling secured EJB-methods

In WL6.1, I have an Ejb with secured methods. The (Swing) client application accesses the Ejb through rmi-iiop using the JDK1.3.1 Orb.
Unfortunately, it seems that the caller identity (which was supplied in the InitialContext lookup) is not propagated
to the server: any call to a secured method
fails with a CORBA NO_PERMISSION Exception.
Non secured methods work fine.
Using the t3 protocol the program also works fine, but that would require
the 25Mb weblogic.jar on all clients,
which is unattainable for us.
Any ideas how this situation can be corrected?
-Allard Siemelink

I am still getting the NO_PERMISSION Exception when using "weblogic.jndi.WLInitialContextFactory".
We use Sun's JRE, version 1.3.1_01.
Am I forgetting something?
My code is as follows:
InitialContext context = null;
try {
Hashtable ht = new Hashtable();
ht.put(InitialContext.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
ht.put(InitialContext.PROVIDER_URL, "iiop://localhost:80");
ht.put(InitialContext.SECURITY_PRINCIPAL, "system");
ht.put(InitialContext.SECURITY_CREDENTIALS, "system_password");
context = new InitialContext(ht);
Object objHome = context.lookup(EJB_NAME);
MyHome myHome = (MyHome)PortableRemoteObject.narrow(objHome, MyHome.class);
MyRemote myRemote = myHome.create();
//NEXT LINE Crashes when method is secured:
myRemote.securedMethod();
finally {
if (context!=null) context.close();
