How to handle an Exception in GP through webdunpro

Hi,
How to handle exception in WebDynpro GP callable objects.
I created exception parameter in getdescription() method like
IGPExceptionInfo processExc1 = technicalDescription.addProcessException("USER_NOT_FOUND");
processExc1.setNameKey("USER_KEY");
processExc1.setDescriptionKey("USER_DESCRIPTION_KEY");
processExc1.setFatal(true);
In my Process I have 2 levels, In block level i am able to see the above created exception using exception tab.
I have created an action with same callable object mapped, this action is mapped to exception handler & selected an repeat option from dropdown.
If any exception occurs in execute method(like UMException) how to call an handler from coding. I tried this code to call a handler
String localizedMessage =textAccessor.getText("USER_NOT_FOUND");
wdThis.wdFireEventTechnicalException(new GPTechnicalCallableObjectException(logger,localizedMessage,e));
this is not working...
Can any one please bring me an Solution.
Thanks in advance.

How to handle the exception in GP(Exception : Activity could not be read)

Hi all
we are getting the GP exceptions as 1) "Activity could not be read" 2) "Action has been stopped"
3) error while processing the item can not be displayed
Please let me know how to handle these exceptions in GP .
currently i got some documents in SDN on GP exceptions but those are related to manual exceptions for example if you enterd wrong data in the inputfield then we can handle those exceptions then it will allow to enter the new value but the exceptions which i mentioned above are new it seems
can you please let me know how to handle or solve those 3 exceptions

How to handle the Exception in GP using executable callabel object.

Hi all,
I handled an exception in GP using Background callable Object. That is working fine.
(Ex: Exception_No_User_Found). The Problem is I am not able to handle the exceptions for normal callable object. I have done the same thing as i did in background callable object except implementing IGPBackgroundCallableObject Class. I have created an WebDynpro DC Project where in getDescription method i declared an Exception and in execute method of component controller I caught the exception if no user found.
Then i created an callable object for this simple DC project. but that is not working i could not catch the exception. when i execute the process it is asking the User ID if i give the wrong userId it is not refreshing back to the user id input form.
But if i test that simple callable object separately it is throwing an Exception when I give the wrong input..
but the same thing is working fine using background callable object.
I couldn't handle the exception for the simple callable object or executable callable object.
Please If anyone bring me the solution that would be appreciated.
Thanks in advance.

Malar.

How to handle XScript Exceptions ?? HELP !!

hey buddies !!!
I am getting the following exception in the browser for some jsp that is using XSCript.
"Caught exception when evaluating expression "MIDC PHASE II DOMBIVALI {E}" with available binding contexts [actionForm, pageFlow, globalApp, request, session, appication, pageContext, bundle, container, url, pageInput]. Root cause: com.bea.wlw.netui.script.xscript.IllegalContextStateException: The context "E" could not be found. "
Its okay that i am gettign this exception but i want to to know how to handle this exception. I tried using a try catch block but it didnot catch the exception and it still showed on the screen. I want to know how to handle this exception in the jsp ...
Please help me ...thanks a lot !!!
Nikhiol

Nikhil--
Can you paste in the tag (with the attributes) that is throwing the expression?
Are you trying to data bind to "{E}"? If so, that's not a supported NetUI data binding context
and the exception is legit. There isn't really a way to "handle" it -- it's more of a runtime error
that occurs during regular development. When the application is deployed, such exceptions shouldn't
occur.

How to handle server event in component through BOL Concept

Hi All,
            Please let me know how o handle Server event in Component through BOL Concept.
Thanks,
Prameela.

Hi Prameela,
If you want the server event to be triggered in the search view, you have to add the code in the GET_DQUERY_DEFINITIONS method.
DATA: lv_getter TYPE string.
CONCATENATE 'GET_P_' <rt_result>-field INTO lv_getter.
    TRANSLATE lp_getter TO UPPER CASE.                    "#EC SYNTCHAR
    TRY.

            cs_result = <rt_result>.
      CATCH cx_sy_dyn_call_illegal_method.

How to handle multiple exception types in JSF 2?

I'm trying to handle multiple exception types in JSF2, including a default error page for any unexpected exception types. The problems I'm having are:
1) ViewExpiredException is handled only when no generic exception handler is specified
2) "Regular" exceptions like NullPointerException are never handled
My managed bean:
@Named
@SessionScoped
public class MyController implements Serializable {
/* A method that does nothing */
public void doNothing() {
    //do nothing
/* Generate a null pointer exception on purpose */
public void generateNpe() throws NullPointerException {
    Object x = null;
    x.toString();
My test page to generate the exception:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core">
<h:head>
    <title>Test page</title>
</h:head>
<h:body>
    <h:form>
        <h:commandButton id="button1" value="do nothing" action="#{myController.doNothing}" />
        <h:commandButton id="button2" value="generate NPE" action="#{myController.generateNpe}" />
    </h:form>
</h:body>
</html>
My web.xml:

<error-page>
    <exception-type>java.lang.NullPointerException</exception-type>
    <location>/error/error003.jsf</location>
</error-page>

<error-page>
    <exception-type>javax.faces.application.ViewExpiredException</exception-type>
    <location>/error/error002.jsf</location>
</error-page>

<error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/error/error001.jsf</location>
</error-page>My questions are as follows:
1) How can we handle "regular" java exceptions like NPE?
2) How can we define a catch-all for unexpected exception types, while still respecting specific exception handlers for VEE, etc?
Thanks,
Benjamin

Is your data model right? If you are adding in one and deleting in another it sounds to me more like a process that an entity, in which case you may revisit your data model and simplify it, add in a session bean with the process method to co-ordinate between the two.
However, if you want to map multiple different tables within a single entity bean it is possible and just part of the mapping. How you actualyl specify it depends on which implementation you are working with.

How to handle system exception in Sync communication without BPM? Help!

Hi Experts
   I have a Synchronous scenario in XI: webservice <------>RFC SAP R/3.
Webservice is making a sync call to RFC FM in SAP R/3 system.
   I want to handle system exception when SAP R/3 is down and send an email alert.
   Can I achieve this in graphical mapping without BPM? How? Kindly provide necessary steps/screenshots for the same.
   Are there any other alternatives for handling system exception apart from mapping and BPM?
Thanks
Gopal

Hi GopalKirshna,
      Yes,You can handle the Exception if at all you are using the RFC.You can achieve this without using BPM.
   Using Fault message you can catch the System Exception and even the primary role for Fault Message is to catch the RFC Exceptions.
   Please refer the Fault messages Notes to achieve this you will understand better.
Hope I am clear.
Please let me if you have any more queries regarding this..!
Thanks and Rewards,
Chandu.

How to handle multiple exceptions by the same code?

Hi, all:
In my situation I want AException and BException handled by the same code, while CException and DException handled by another code. How can I write my try-catch code in a simple way? Of course I can do the following:
public void TheMainFunction() {
    try {
    } catch (AException e) {
        Handle_AB();
    } catch (BException e) {
        Handle_AB();
    } catch (CException e) {
        Handle_CD();
    } catch (DException e) {
        Handle_CD();
private void Handle_AB() {
private void Handle_CD() {
}But is there a simpler way?
Thanks in advance.

If you have one or two places in your code that need multiple exceptions, just do it with multiple catch statements. Unless you are trying to write the most compact Programming 101 homework program, inventing tricks to remove two lines of code is not good use of your time.
If you have multiple catches all over your code it could be a code smell. You may have too much stuff happening inside one try statement. It becomes hard to know what method call throws one of those exceptions, and you end up handling an exception from some else piece of code than what you intended. E.g. you mention NumberFormatException -- only process one user input inside that try/catch so it is easy to see what error message is given if that particular input is gunk. The next step of processing goes inside its own try/catch.
In my case, the ArrayIndexOutOfBoundsException and
NumberFormatException should be handled by the same way.Why?
I don't think I have ever seen an ArrayIndexOutOfBoundsException that didn't indicate a bug in the code. Instead of an AIOOBE perhaps there should be an if statement somewhere that prevents it, or the algorithm logic should prevent it automatically.

How to handle JCO Exceptions at JCO (RFC) function call

Hello Forum,
I am implementing an JCO Server scenario.
I use dynamic repositories like Example7.java from the JCO documentation.
Example7 throws an JCO.AbapException if anything went wrong, e.g. the function is not implemented.
How to react on this AbapException?
The examples in SAP Help documentation only catch
SYSTEM_FAILURE and COMMUNICATION_FAILURE.
All other RFC modules I have seen which declare the function modules to be used by dynamic JCO repositories (like Example7.java) do not define any other Exception parameters.
But these two are only thrown and caught when something with communication went completely wrong, e.g. RFC not found.
But when RFC can be reached and the JCO Server is executing the Java method, an AbapException could be thrown on error. How to react on this?
In my implementation based on the examples I always get a ABAP dump. The dump says:
Exception named without message text. Why that name?
How to handle this type of exception in order to avoid the dump?
Can anyone post an example please?
Thanks,
Carsten

Hi Micky,
thanks for your quick response.
If so, to throw JCO.AbapException on JCO Server side is not correct?
What I do is throwing the JCO.AbapException (like in the JCO Example 7).
At the RFC call in APAB I handle both exceptions SYSTEM_FAILURE and COMMUNICATION_FAILURE like
CALL FUNCTION 'MY_JCO_FUNCTION_MODULE'
    DESTINATION JCO_DEST
    <...>
    EXCEPTIONS
      SYSTEM_FAILURE        = 1 MESSAGE RFC_MESS
      COMMUNICATION_FAILURE = 2 MESSAGE RFC_MESS.
This works as far something with RFC is wrong, e.g. Server can not find the function or Server not reachable.
But the AbapException thrown by the JCO Server (Java) is not handled that way. Why?
Sorry if this is the wrong forum but I tried posting in Netweaver integration and got no answer for 1 week and because it's ABAP related I thought the topic suites here.

      } catch (RuntimeException re) {
        throw new Exception(re.getLocalizedMessage());
      } catch (Exception e) {
        throw new Exception(e.getLocalizedMessage());
    } finally {
      em.close();
}Whatever the error type, i always get the message : Transaction does not exist.
Kindly advice how can handle these SQL error (table not found, column must not be null, column not found, ...)

Hi,
Whenever there is any error inside the WebService or while it's processing ...it throws Exceptions ..We can handle these exception by our own to make the Exception details more readable.....For that we can create our own SOAPFault message...
Please refer to the below Posts...

How to handle SYSTEM_NO_MEMORY exception

Hello,
is there a way to handle the SYSTM_NO_MEMORY exception in a Z-Program? I want to show the user an error message with hints how to prevent this short dump instead of having the system showing the short dump.
I tried to use TRY-statement but until now I wasn't successful.
Thank you for your help,
Stefan

Hi Stefan;
It seems there is no way to handle that exception as it's memory problem during run time.
Please try to free unusable internal tables in each subroutine.

How to handle the Exception when RegisterEventProcessorAsync

In our Cloud Service project, we have 2 instances for work role (deploy to Azure), the work role is consume events from the EventHub using EventProcessorHost).
When we want to register EventProcessor to consume data (see below):
await eventProcessorHost.RegisterEventProcessorAsync<eventProcessor>();
Sometimes we will got the Exception:
Microsoft.WindowsAzure.Storage.StorageException: The remote server returned an error: (412) There is
currently a lease on the blob and no lease ID was specified in the request.. ---> System.Net.WebException: The remote server returned an error: (412)

If we got the Exception, we won’t got messages any more.
From the Call Stack, we found it was cause by delete the Blob. So we wonder that, when we call
RegisterEventProcessorAsync,
the hub will delete the blob and renew one in Storage?
If we delete the blob for the EventHub manually and then run our server again. It worked as usual.
But we can do it like this way manually, so is there any way to handle the exception in code to make the EventProcessorHost worked?
Thanks so much!

If we use different blob container name for different EventProcessorHost, is it a workaround for the issue?
   var
eventProcessorHost = new
EventProcessorHost(
                hostName,
                hubName,
                consumerGroupName,
                serviceBusConnectionString,
                storageConnectionString,
leaseContainerName);

How to handle RFC exception in XI

We have developed a proxy-> RFC scenario. But its not able to handle the RFC exception. In case of an exception the response payload is as below
<rfc:Y_BAPI_GET_POSTING_PERIOD.Exception xmlns:rfc="urn:sap-com:document:sap:rfc:functions"><Name>RFC_ERROR_SYSTEM_FAILURE</Name><Text>Screen output without connection to user.</Text><Message><ID>RFC_ERROR_SYSTEM_FAILURE</ID><Number>044</Number></Message><Attributes><V1>DYNPRO_SEND_IN_BACKGROUND</V1></Attributes></rfc:Y_BAPI_GET_POSTING_PERIOD.Exception>
Is it correct way to get exception from RFC in such a way or the error/exception text should come in RETURN part of the RFC response?
What is the best approach or solution to handle the sync. RFC call exception in XI?

Hi,
You can create a Fault Message Type and map the RFC exception text to this.
In the interface mapping in addition to Request and response
mapping you will get an additional fault message mapping.
This will handle your exception properly.

Who should catch the exception if it is thrown?
You need to signal the error in any other way. What should happen if the connection can't be established?
