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 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 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

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

Fault Bindings using BPEL.xml

Hi
I have a peculiar problem with fault bindings. I have a webservice from target application hosting two different operations. I need to have the fault policy being applied to one operation and the other operation should not have any fault policy defined on it.
I tried in the following way.
Approach 1. In Fault Bindings.xml i have added the entry for the operation for which policy needs to be applied.
This is working fine as expected.
Approach 2. I have added the entries in bpel.xml and fault-bindings does not contain any entries related to this operation. In this approach the problem am facing is for both the operations the policy is getting applied.
I need to go with the second option as all my bpel processes have fault policies at the bpel level instead of domain level.
Can any one give me some clue on this
Thanks
Vamsi

Entries in BPEL.XML file
<faultPolicyBindings>
<partnerLink faultPolicy="EAIFaultPolicy"/>
<name>BSNLUpdateCollectionStatus</name>
<portType xmlns:CollectionProvCreateSO="http://siebel.com/asi/">CollectionProvCreateSO:BSNLUpdateCollectionStatus</portType>
Entries in Fault Binding.xml has been removed for this
One observation i had is both the WSDLs has same SOAP Address location but the operation names are different.
Does this have any impact for this kind of behaviour
Thanks

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,
Jose John

Thank you very much for your reply.
Following is the wsdl file,
relevant part of the WSDL file
<message name="Exception">
<part name="fault" element="tns:Exception"/>
</message>
<portType name="PostConstraintChecker">
<operation name="check">
<input message="tns:check"/>
<output message="tns:checkResponse"/>
<fault message="tns:Exception" name="Exception"/>
</operation>
</portType>
<binding name="PostConstraintCheckerPortBinding" type="tns:PostConstraintChecker">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<operation name="check">
<soap:operation soapAction=""/>
<input>
<soap:body use="literal"/>
</input>
<output>
<soap:body use="literal"/>
</output>
<fault name="Exception">
<soap:fault name="Exception" use="literal"/>
</fault>
</operation>
</binding>
Is this correct? Do you see any problems in this? Please let me know if you need any more information which will help you in debugging the issue.

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

Using Fault handling framework for executing Database procedure

We have a requirement wereby we have API to be executed on Oracle DB which would return a code saying 0 or 1.
I meaning error.
Now with regards to exception handling we require that we receive remote fault we retry for 3 times & if not successful have a email sent out & a human intervention.
This can be easily taken care by having define this in Fault polciy.xml
Another requirement is when the API fails for some reason & we get returncode as 1.Now we would like ot invoke the same policy for this type of error.Although BPEL instance is not failed.But we can throw custom fault.
Now the APi's that we have can be called in 3 ways.
1.In each instance we call API exactly once
2.In each instance we call API in a loop for each record in message.Hence if 10 records are there in message & while executin 7th time it failed then how to handle reminaing records?
3.In each instance we call API only once but submit all 10 reocrds at once.And at same time 7th record fails then whats best way to handle this?
We realy want to use fault handling mechanism because it gives a lot of options of replay rethroew continue...but given the requirement can somebody point out a right way of using fault policy?
Thanks

U can archive the records in archive tables once the database adapter polls the data.

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.

3.- Then i create an simple async BPEL case for fault handling with a DB BPEL Adapter using a wrong Jdbc string for instance Bad SID database (deliberately , The correct is XE not XE1).
Then i test it, and with audit trail in BPEL Console, i can view the 2 retries that i indicate in the descriptor, but after [FAULT RECOVERY|http://forums.oracle.com/forums/] Marked Invoke activity as "pending manual recovery, it have a exception.
* In normal case with OC4J, after last line, the process is ready for recovery in a manual step.

For all other activities use the BPEL fault handler.

Unable to handle fault thrwon by BPEL in ESB

hi ,
my bpel process(syncronous request&reply) is throwing the remote fault and my ESB process is not picking the fault even both fault schema are same.
error message:
<MSG_TEXT>An error occurred for port: BPEL_OC4J_SOAP_Provider: javax.xml.rpc.soap.SOAPFaultException: business exception.</MSG_TEXT>
can any one throw some light on this.
PS:my bpel fault schema is not part of response schema( so cant use reply activity inside fault handling section)
Thanks,
Narasimha.

There is a bug in the ESB, what version are you on. If on 10.1.3.3 you will need to apply the latest MLR patch.
cheers

Fault handling in osb using publish

Hi all,
i am new to OSB, every thing is working fine. i will explain how we design the basically we have inbound and outbound. call inbound as 'aaaa' and outbound as "bbbb". we have created the proxy and BS which will communicate with EBS, BAM and B2B. i have created BS for all the three. from PS i used 2 assign and 1 publish activity. we are publishing directly to BS correspondingly. since i am not using any route activity i could not get the error back or any invocation error messages. can any one tell how to capture the error and place it into BAM report. we can transform data to BAM we just need to get the details about the fault handling in OSB.
thanks ----

Hi prabu,
thanks for your response.
As we have the discussion on this issue for quit a long time. i have configure the error handler in the proxy services when my EBS throws the error. error handler come active and some data is published to bam. here i got the problem is that, the PO which we are sending is one way or fire and forget when using Publish action. when the PO hit the EBS, i.e. when error message is passed through the test XML, error is occuring and and reporting to bam with some null values. i need to capture the data processed at that transaction. is it possible to capture the data in error handler which is errored out in message flow of PS.
can you please help me
thanks--

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 !
