Create custom fault type in BPEL

Hi
Quick question for you all on a sunny Friday in London! Has anyone created a custom fault type in BPEL?
If so, I'd appreciate a quick how to. I'm guessing it's a case of declaring a new type in your WSDL, but does it have to extend a type or something?
Many thanks
Chris

From a rainy sunday eveving in Holland,
You just create your own message type. Then you defien in your WSDL the fault, and point it to your own message type.
In de BPEL process, you just name the name-space and use the Throw activity that uses your message type.

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 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 - 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

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 !

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.

Fault Handling in Mediator

Hi,
We have a DBAdpater to retrieve the data and a mediator to invoke the DBAdapter. In cases like No Records we want to create a soap fault. So we implemented Mediator Java callout and overriden postRouting() to read the response message and create a soapfault.
[ we referred to blog http://technology.amis.nl/blog/6669/soa-suite-11g-introducing-mediator-java-callouts-for-debug-audit-and]
but when we tried creating SOAPFault and add it to the response message, while execution , the response message is being parsed and seeing the fault it is throwing the exception below:
java.lang.Exception: oracle.sysman.emSDK.webservices.wsdlapi.SoapTestException:
This is a fault.
at oracle.sysman.emas.model.wsmgt.WSTestModel.invokeOperation(WSTestMode

I found that if exception from mediator is not handled, then the exception is throw as system fault as shown above.
So we tried implementing external fault handling - by creating fault-policies.xml and fault-bindings.xml and a java callout.
fault-bindings.xml
<?xml version=”1.0" encoding=”UTF-8"?>
<faultPolicyBindings version=”2.0.1" xmlns=”http://schemas.oracle.com/bpel/faultpolicy”>
<composite faultPolicy=”SOM_ServiceFaults”/>
</faultPolicyBindings>
fault-policies.xml
<?xml version="1.0" encoding="UTF-8"?>
<faultPolicies>
<faultPolicy version="2.0.1" id="SOM_ServiceFaults">
<Conditions>
<faultName xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" name="env:Fault"> 
<condition>
     <action ref="ora-custom"/>
</condition>
</faultName>
<faultName xmlns:medns="http://schemas.oracle.com/mediator/faults" name="medns:mediatorFault">
<condition>
<action ref="ora-custom"/>
</condition>
</faultName>
</Conditions>
<Actions>
<Action id=”ora-terminate”>
          <abort/>
     </Action>
<Action id="ora-custom">
<javaAction className="gm.som.FaultPolicyJavaAction" defaultAction="ora-terminate">
<returnValue value="ora-terminate" ref="ora-terminate"/>
</javaAction>
</Action>
</Actions>
</faultPolicy>
</faultPolicies>
But still getting the error.Appreciate any help on this.
Thanks in Advance,
Subhashini

Not exactly but doing it the other way around by copying the fault msg to output variable and check flag for the response in my initial requester process then throw fault accordingly.. didnt have much time as it was holding back my other deliverables
Thanks a lot for your time

Best Practice for Implementing Exception Handling in BPEL

Hi All,
what is the best practice and the approach to follow Exception Handling in BPEL.
1) Do we need to implement Exception Handling in BPEL as we do in Java, means
     method 3 throws error to method 2 (if any) and
     method 2 throws error to method 1 (if any) and
     finally method 1 throws error to the main Class.
If we replicate the above scenario to BPEL
In BPEL main Scope have Custom Fault, Catch ALL
     Each Invoke is surrounded by a Scope Activity with Remote Fault, Binding Fault & Custom Fault
and follow the paradigm of Java, assuming we have Inner Scopes
     [ OR ]
2) In BPEL main Scope have all exceptions defined like
     Remote Fault,
     Binding Fault,
     anyOther System Fault (selectionFailure / forcedTermination),
     Custom Fault (if required) and
     CatchALL
     and also
     each Invoke is surrounded by a Scopes Acitivity with Custom Fault (business fault) exception Handling
I feel 1st one may not be a good practice, may be i am wrong...
Any Suggestions from experts.
Thanks in Advance
anvv sharma

Hi-
In you can create different scope and use catch branch to catch binding, remote, custom faults, business faults etc. If an error happens in a scope it will not move to the next scope( eg: you have 3 scope, error occured in 2nd scope then it will not propogate to the 3rd scope. One thing to be noticed here is your transaction in the 1st scope doesnt gets commited when an error happens in 2d scope).
You can have a catch all to catch error which are not being caught at catch level. So if any error happens which is not defined in catch block then then it will be caught in catch all branch.

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
Edited by: anantwag on Mar 23, 2011 6:31 AM

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

Custom fault message from OSB is not throw in BPEL

Hi,
I have created a custom fault error in OSB which is sent to BPEL.
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Header/>
<env:Body>
<env:Fault>
</env:Fault>
</env:Body>
</env:Envelope>
If my namespace in FAULT tag is "http://schemas.xmlsoap.org/soap/envelope/",
message is understood as fault IN BPEL. But if I change namespace, BPEL understands as reply message.
How can I use my custom fault message with different namespace as http://schemas.xmlsoap.org/soap/envelope/ ?
Regards,

SOAP Fault has a defined structure and defined namespaces. It does provide a placeholder for custom data though. Just like you can not change the namespace of Envelope of Body, similarly you cant change the namespace of Fault(if you want it to be recognized by the client apps). Any custom data you want to send in the SOAP Fault needs to be set as a child of 'detail' element of SOAP Fault. This custom data can have any namespace you wish. This Custom XML will be the element you define as Fault element in your WSDL
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Header/>
<env:Body>
<env:Fault>
<faultcode>env:Client</faultcode>
<faultstring>some error string</faultstring>
<faultactor>somedata</faultactor>
<detail>
{here you can put your custom XML content in any namespace which you have defined in the WSDL}
</detail>
</env:Fault>
</env:Body>
</env:Envelope>

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.
