Business Faults handling

Question

I am having a simple BPEL process and i am trying to catch fault within the process.
1.file adapter read the xml file when available and process it
2. XML is parsed and plsql pkg are invoked via DBadapter,
I want to catch business faults. How should i use fault variables and how to assign them to a wsdl.
WSDL part is confusing me. Can you throw some light on this please
Regards

Answer 1

Can u make it bit clear?
In the scenario u mentioned File adpater and DB adapter can not throw a business fault.
If U want to throw a business fault in your service u can use throw activity.
Then u catch it using catch block.
If you want to expose the business fault thrown by you in the service to the service consumer add below segment to the wsdl of your service
<binding .... >
<operation .... >
<fault>*
<soap:fault name="nmtoken" use="literal|encoded"
encodingStyle="uri-list"? namespace="uri"?>
</fault>
</operation>
</binding>
namespace is the URI u define while throwing fault in your service.
