Fault Handling in BPEL - Continue after Catch Block

Hi,
I have a catch block in my BPEL process.
On exception, the catch block catches the error and terminates the BPEL Process.
Is it possible to loop back the flow after the catch sequence?
Thanks,
Venkat

Hi,
Thanks for your reply
Sorry, I was not clear with my question.
I have a infinite loop in my process. Inside the loop I have an invoke operation(Invokes another BPEL process) and a wait operation. If any exception occurs, my BPEL process terminates. However, I wanted my BPEL process to just continue in the loop.
I solved the issue with the help of this How to handle fault when BPEL process is polling a FTP server which is down
i.e, using the Scope activity. Place my invoke operation inside a scope and put a catchAll block only for that scope. Its working fine
Thanks,
Venkat

Exception Handling In BPEL By using Catch Blocks or Fault Policies Or Both

I have a confusion regarding
Exception handling :
When Should i go for 1)Catch Block (Remote , or binding ) in bpel for exception handling .
2)Fault Policy , Fault binding.xml
Currently iam using catch blocks , but even fault policy is good , but can i use both...
Currently in My bpel ,when any error occurs i have to send a error notification by Email .
Currently i have exposed the email service which shuts emails and write a file with errored Message.
Hence if any error i will catch i in a parent BPEL, i will just invoke the above email, service .
So anybody can help me by giving the suggestion how to go for the best approach

Currently in My bpel ,when any error occurs i have to send a error notification by Email .
Currently i have exposed the email service which shuts emails and write a file with errored Message.Seeing your use case I will suggest you to use fault handling framework (fault policy). Fault handling framework should be used where you need generic error handling framework which handles all the faults occured in any composite component. Generally BPEL catch block should be used to propagate error info/fault back to the client/to fault handling framework or to consume an error

Fault Handling in BPEL process

hi
We have to develop an application which involves several BPEL processes and proxy service(OSB) and JMS queue etc.
What is the difference between Fault Management Framework in SOA11g and normal fault handling(using catch and throw activities)?
which one we should prefer for fault handling in our application n why?
Plz help thanks in advance.

Hi-
In Normal Fault handling process, you will be able to catch the faluts only but in Fault Management Framework if a fault occurs the framework catches the fault and performs a user-specified action defined in a fault policy file associated with the activity. You can also have a human intervention prescribed in it, where you perform recovery actions from Enterprise Manager.
Pls go throgh the below post for detailed description

Fault handling using BPEL

Good, I'm working on a research project and I have been assigned the task of processing errors in SOAP BPEL.
I've been searching on Internet and the most commonly methodology used is soap-fault with throwing and catching exceptions in BPEL process.
I wonder if I can do it in a more proactive and comprehensive way, catching those exceptions through a web service, and if possible, how can the BPEL process send the information encapsulated in the soap-fault to the web service?
If there is another way of treating errors or someone can suggest me another way, I would be very grateful.

I am not clear on your objective, but in so far as BPEL SE Component of Open-ESB Project, running on JBI is concerned you can read more about Fault handling and other features of BPELSE here at http://wiki.open-esb.java.net/Wiki.jsp?page=BPELSE. Also, you can find some working examples on this page http://wiki.open-esb.java.net/Wiki.jsp?page=HowToDo

Fault Handling in BPEL

Hi,
Can anyone explain me how do I handle the faults in my BPEL process. What I want to do is whenever any Faults occur in my Invoke activity I want to capture the error messages and send an email to myself with the error messages. Appreciate if anyone can help me out here with the design process. I'm new to BPEL and if there is any step by step design document it would really help me.
Thanks

Return statement at the end of try or after catch blocks

Hi
Can anyone tell me which is the better practice - to put the return statement at the end of try block or after all the catch blocks ie at the end of method.
Eg
Method A()
String str;
try{
str= [some code]
return str
catch(Exception e)
System.out.println("Exception");
} // end of method
OR
Method B()
String str;
try{
str= [some code]
}catch(Exception e)
System.out.println("Exception");
return str
} // end of method

I always try to work with only one exit point for each method.
For readability I always put the return statement as close to the end of the method as possible.
In this particular question,
I think you should put the return at the end of the method (for readability, since this is what you are
familiar with), but when I have a try-catch clause, I usually have an unrecoverable error and
should throw this further down the tree, so it usually becomes
try{
   return
}catch(...){
   // write out some logging information
   rethrow exception or throw another exception
}I think you should NEVER reflect the occurence of an error in the return-value of the
method when an unrecoverable exception occurs. Just rethrow this exception or throw another method.
Other methods look like
   Object result = new...
   return result;As for the specific case of a repetitive if-case:
This is possible in two versions:
With one return and a result-object
Object result = new ...
if(..)
   result = ...
else if(..)
   result = ...
return result;With every time a return
if(...)
   return ...;
else if(...)
   return ...;For me the above two possibilities make no difference,
but I find the second version (which I hated when I began programming)
to be somewhat more of a (self-made) standard nowadays.
But I do not think this particular case makes much of a difference.
kind regards,

An issue with BPEL fault handling

Hi,
I need to catch an exception in my BPEL process. The exception is thrown from a partner service(in java). I am using the catch fault handler in BPEL to catch a specific fault.
1. When I give "systemFault" as the faultName its catching the fault
2. But when I give "Exception" as the faultName its not catching the fault
In the second case server log gives me the following fault,
BPCOR-6135:A fault was not handled in the process scope; Fault Name is {......
Can you please help me to figure out the problem here.
Please let me know if you need any more information.
Thanks in advance,

Can error handling framework use fault policies and BPEL catch blocks

As part of an integrated customer solution that makes substantial use of SOA Suite (including OSB, BPEL, Mediator, etc) we are in the process of designing an “Error Hospital” subsystem to expose a web service API specifically for BPEL services and/or the OSB layer to call whenever they encounter an exception which they cannot handle so that the appropriate user is notified of the error (via email) and the error is recorded (in an appropriate common fault format, with error codes elaborated into more meaningful descriptions, etc) within OEM, immediately prior to returning the exception to the caller.
The problem we have experienced in our design is as follows:
•     We have an error handling service to be called, inside the BPEL catch blocks, when an error occurs to notify the appropriate user, via email, that an error has occurred;
•     We also use the error handling XML fault-policies so that we can recover from an error using OEM (via human intervention);
•     The error service needs to be called before the process is suspended (waiting for human intervention) so the email notification and error message formatting occurs BEFORE the recovery action. Unfortunately the fault policies trigger BEFORE the error handler is able to transform the error into the appropriate format and notify the user so the error recorded is not the reformatted one and the user is never notified.
The key question is how can a BPEL, upon catching an exception, invoke the error handling service and AFTER that send the error to OEM (and have the process suspended).
It seems the two mechanisms "cannot play nicely together"

The fault management framework catches all faults (business and runtime) for an invoke activity only.
For all other activities use the BPEL fault handler.

While the policy definitions are working fine for runtime faults, it is not working for selectionFailure fault. Unless I add catch block in the bpel definition, the instances are faulted. Does fault handler ignores standard faults ?
Please help. Thanks in advance.

Yes, catch and catchAll branch can catch all the faults.
fault policies will be executed only when the invoke activity fails.
if both fault policies and catch and catchall brnaches are there,
a. if invoke activity faults, then the fault policies will be executed.
b. any other activity fails, then the catch or catchAll branch will be executed.
Please look into these posts below...

BPEL Fault Handling Framework, default Action to send Notification

All,
I'm using SOA Suite 11g R1
Is there a way to send (email) Notification without Java coding in the BPEL Fault Handling Framework ?
I would like to, when catching a fault in the Fault Handling Framework (remotFault/bindingFault) -> send a Notification and then HumanIntervention.
Thanks
Bjorn-Erik

Hi,
one option wud be to send it to human intervention and then rethrow the fault back to bpel....here u can define the email activity in the catch handler...try it.

Creating Fault Handling and Exception in Oracle BPEL

I am following BPELtutorial-Orderbooking.pdf and have successfully reached chapter 6 i.e. Creating Fault Handling and Exception in Oracle BPEL. Everything went fine except this one... i.e. after implementing the Fault Handling and Exception in Oracle BPEL when I execute my process and enter CustId that begins with 0.... the invokeCR generates error message as follows as expected:
<NegativeCredit xmlns="http://services.otn.com">
<part name="payload">
<error xmlns="http://services.otn.com">Bankruptcy Report</error>
</part>
</NegativeCredit>
However, the execution proceeds ahead instead of terminating. The tutorial states that the BPEL process should terminate as the SSN is invalid, can anyone please tell me whats going wrong.. ?

Well not exactly.... but when click on the 'Audit' sheet under BPEL Console for this instance, I can see the following:
invokeCR (faulted)
[2006/03/20 10:35:07] "{http://services.otn.com}NegativeCredit" has been thrown. less
<NegativeCredit xmlns="http://services.otn.com">
<part name="payload">
<error xmlns="http://services.otn.com">Bankruptcy Report</error>
</part>
</NegativeCredit>
The above is exactly what the tutorial states will be the output, so I presumed that the exception must have fired !

BPEL Fault Handling

Hello,
I am working on imlementig of fault handlers in my test process. i have the service impl in axis with fault message as well. when i try to catch the exception within catch-block it works fine but the activities defined in the catch block wont be executed...damn...no idea what is wrong in this definition...and secondly if i work with catch-all construct i can catch the error and the activities of the catch block will be executed but the further activities (outside of catch-block) are executed as well...
has anybody an idea what is wrong here?
thanks a million!

In Oracle document for Fault Handling http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10224/bp_faults.htm#BABIGGIB it is given that fault-policies.xml adn fault-bindings.xml can be placed in same directory of composite.xml or it can be placed in common location.
I take that common location as MDS repository. Can anyone tell me how can i place the two files to MDS repository?
If my understanding is wrong can you please tell me how to achieve the second crieteria?
Regards,
Sundar
