11g: Help regarding fault handling framework

Question

I am trying to implement a POC demonstrating the fault handling framework using fault policies. I am trying to handle remote and business faults. These faults are being thrown explicitly in the code. But I dont see the framework coming into picture. Here are the fault policies and fault bindings files
The POC does the following
1. If input is R, throws a remote fault.
2. If input is B1, throws a business fault. There is a catch defined for this. But as we also have a policy for this error, we expect the policy overrides the catch
3. If input is B2, throws a business fault. There is no catch defined for this. We expect the policy to handle this.
4. If any other input, we return a string.

</condition>
</faultName>
</Conditions>
<Actions>
<Action id="ora-human-intervention">

</Action>
</Actions>
</faultPolicy>
</faultPolicies>
Here is the fault-bindings.xml file

</faultPolicyBindings>

Answer 1

I created another bpel in the same composite that calls the original bpel. So now, those errros are supposed to travel to calling bpel.
Fault policies are coming into effect now. So, one part of the problem is solved, that atleast syntax and all is correct, and the fwk does work (!) but another one has opened - why is the fault not getting handled by the fwk if there is a single bpel that is throwing and not catching those faults.
Also, even in this new avatar, fault b1 is getting handled by the catch in BPEL process, while the fault policies are supposed to override any catches in bpel code.
What I was attempting was, throwing the fault in a bpel process and expecting the fault handling fwk to handle it.
It turns out, the framework is not capable of doing this, its only capable of handling faults coming after an invoke activity.
Consulted Oracle Support on this. Their response
The behavior within the single composite you are seeing is correct and is by design. As the documentation states:
http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10224/bp_faults.htm#BABIGGIB
If a fault occurs during runtime in an invoke activity in a process, the framework catches the fault and performs a user-specified action defined in a fault policy file associated with the activity.
The fault management framework catches all faults (business and runtime) for an invoke activity.
So the above means that unless the fault is thrown in response to an invoke activity the Fault Policy set will not be triggered, which has been confirmed through the test you have uploaded. Please let me know if you have any questions or concerns.
