Hi,
I need some clarification on Fault Handling Framework...
Scenario:
My BPEL Process is Asynchronous.(10.1.3.3.1) and I tryed to invoke the another BPEL Process( which is used to select the Fname from the table using DB Adapter) . In the Main BPEL Process I have the Fault handling Framework and I done necessary changes in the bpel.xml. This is successfully working for Invoke Activity when ever an Remote or Binding Fault occurs in the Sub-BPEL Process and this Fault is send to Fault-Policy.xml in the server(bpel/domains/default/config/fault-Policy) and works accordingly to the action mentioned in the policy xml....( I have also made changes in the fault-bindings.xml ).

How ever this Framework is working fine for every actions.

Need Clarification:

1) Only the Binding and Remote faults will work for the Fault handling Framework.
2) can we use User defined faults (Buissness Faults,,,) for this........because I used the User defined faults to invoke the fault-policy.xml and it won't works....
3)Only Invoke Activity can be handled for this Framework or any Other Activity........
4)How to handle other Activity in the Fault-policy.xml...
5)Any difference for Asynchronous or Synchronous in this Fault Handling Framework.......

I also referred the Oracle SOA Suite New Feauters PDF .......
Can any one send me the related documents and try to help me on this.
Please help me on this.......

Thanks,
Ashok.
