How to handle exception in driver program
Dear Friends;
I have been assigned to object wherein i have to display a form for which i am gathering all my data in smartform and my requirement is that when first time data selection failed i.e. no data found against selected order number (AUFNR) then i have to display information message and the return back to my selection screen wherein i am taking process order (AUFNR) from user . I guess we cannot display messages when we are in smartform function module so what i did is in my form interface i have created my own exception and i need to handle it in my driver program where it can be possible for me to display information message and return back to selection screen. But i don't know how to code it only i have is rough idea Can u please help me out???
If possible send me example code
Regards;
Parag
HI,
Before calling the Generated Functionmodule of the smartform, just write the code to check the data and write all the validations, if any one failes, then raise the error message, then the Selection screen will come again if the error message occurs

How to handle exceptions in web dyn pro
Hi Frndz....
Can any one kindly xplain how to handle exceptions in web dyn pro..like we hav exceptionhandling in java ....so is there any for NWDS
THANKS & REGARDS
RajeshHi,
Web Dynpro Java is basically java only.i.e You program in java. Hence exceptions are supported in the same way as in java i.e. via try,catch and finally block.
Additionally,
In 04/04s if you create a method in any controller in web dynpro you cann't specify exception that can be thrown in the method. This is now possible in new programming web dynpro model in CE.
Hence when creating a method you can also specify custom or core java (lib)excetions.

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

Its occurs because you're trying to access a objects with null reference. Or you forgot to create an instance or an error occurs during the instance creation. So You should put all your "Procedures and business logic" inside a Try/catch block. as follow.

The TRY block defines a guarded area whose class-based exceptions can be caught in the subsequent CATCH blocks. If no exception occurs in the TRY block and it reaches its end, the system continues the processing after ENDTRY. If a class-based exception occurs in the TRY block, the system searches for an exception handler in the same or an external TRY control structure.

You can the following two ways.
1)Go to your Interface or the Form which you have created -> Use Display object list to see form and Print program that are linked to that Interface.
2) You can use NACE transaction->
Select the application type, and Click Output Types->
Choose the Output type and Click on Processing Routines
Here you can find the Driver program and and the Corresponding PDF Form.

I have catch some exception ,but i don't know how to handle them. I means that if a caller call my method, the caller how to know exception .
This is my codes:
public byte[] encrypt(String algth,byte[] obj,Key key){
byte[] data=null;
try{
Cipher cipher = Cipher.getInstance(algth);//encrypted secretkey
cipher.init(Cipher.ENCRYPT_MODE,key);
data=cipher.doFinal(obj);
}catch(NoSuchAlgorithmException e){
}catch (NoSuchPaddingException e) {
}catch(InvalidKeyException e){
}catch(IllegalBlockSizeException e){
}catch(BadPaddingException e){
return data;
Can you tell me how to handle NoSuchAlgorithmException ,NoSuchPaddingException,InvalidKeyException and so onyou dont. you're stuffed. If there's 'NoSuchPadding' or NoSuchAlgorithm, or the encryption fails (the other 3), nothing you can do at that point will change that fact.
2 options.
return null, and check the return value every time you call the function
throw an exception, either the exception caught, or one of your own design with information pertinent to your application. -
we atarting new project first module.front end java back end oracle.
when we are writing procedures and functions in backend when errors and exceptions are raised we insert that values into error log table which contains all eroor and exception messages.
but when we run actual application front end people has to know which error is occured in back end .how to handle to display theese errors into front end peopleyinghan wrote:
you can add an out parameter to the procedure, output the error message by the out parameter, then JAVA can get the erro message.This is about the worst thing you could do. Better would be not to handle the exception at all.
Also the op might consider googleing for the log4plsql package which does something similiar as the popular log4j routine.
There seems also a beta version available for 10g that uses DBMS_UTILITY.FORMAT_ERROR_BACKTRACE/FORMAT_ERROR_STACK.

How to handle exceptions in a Service
Hi,
I'm trying to get the new Service (background thread) stuff working and am close but I have a problem with handling exceptions that are thrown in my Task. Below is my code, does anyone know if I am doing something wrong, or is this just a flaw in the system at the moment:
Here is my service:
public class TestService extends Service<String>
protected Task<String> createTask()
return new Task<String>()
protected String call() throws Exception
System.out.println("About to throw exception from inside task");
throw new Exception("Test failure");
}Here is my code using this service:
public void doTest()
final TestService test = new TestService();
test.stateProperty().addListener(new ChangeListener<Worker.State>()
public void changed(ObservableValue<? extends Worker.State> source, Worker.State oldValue, Worker.State newValue)
System.out.println("State changed from " + oldValue + " to " + newValue);
test.start();
}When the task throws its exception I was hoping to get a state change to FAILED but the callback is never triggered. I've tried listening for invalidation of the state and also tried listening to all the other properties on Service (running, progress, exception, etc). There doesn't seem to be any feedback after the exception has been thrown.
Am I using this wrong, or is it a bug?
Cheers for you help,
zonskiHi,
This was working in the build #32. I updated the JavaFX to build #36 and it stopped working.
I checked in the latest build #37 as well which was released last week and this doesn't work here as well.
If the task is succeeding the state is getting changed to SUCCEEDED but in case of an exception there is no change in the state

How to handle exceptions / errors in LiveCycle
Hello All ,
I want to handle some exception / errors that may arise while the user is filling the form so that the JavaScript console should not show any error rather we can simply show an alert / message .
Say I got a dynamic table where the user can add / delete row at run time . There is a minimum count for the no.of rows . Suppose the user clicks the delete button without adding a new row then the JavaScript console will show error . I know we can handle this by using if else statements where depending on the instance manager count the deletion of rows are permitted . I want to know is it possible here to write a code to handle exception considering this thing as an exception without using the If-else statement ?? Just a thought.
Thanks.
Bibhu.What you're looking for is the javascript:
try{
// code
} catch (err) {
// fail code
However, this is not the right way to solve your problem: Exception handling is for handling exceptions, and a scenario that you know can come to pass (such as the user clicking the removeInstance button when there are none to remove) is not an exception.
Don't misunderstand me - putting code inside try/catch is 'good developer manners' (I do it myself all the time), and I strongly encourage you to do the same. Although only for handling exception sprung from code that you think should work just as fine without them.
A better way of solving your particular problem is to remove the minus-button if there are no instances to remove. -
How to handle exceptions in BAPI
Dear Gurus,
Is there any specific way to handle exceptions in BAPI? I mean the way one handles exception in FM...can tat be applicable to BAPI or is there something specific.
Regards,
ShikuThe export parameter Return can be implemented as follows:
As a structure, whereby it must be defined in the function module as an export parameter, as well as in the method in the BOR.
As a table, whereby it must be defined in the function module as a table parameter, as well as in the method in the BOR as an export parameter.
Before filling the Return parameter you should either initialize the structure with CLEAR or the table with REFRESH and CLEAR.
If the return parameter is not set or is set to an initial value this means that no error has occurred.
The Return parameter may be based on the following reference structures:
BAPIRET2
You must use this reference structure when developing new BAPIS.
BAPIRET1, BAPIRETURN
These reference structures are still partly used in old BAPIs.
Both structures must be filled in the logon language.
