Hi Jaliya,
First of all THANKS for replying. I know you are too bussy.

The answer to your question is:
Yes I've tried the same service without Sandesha and Just pure Axis2.
And it works fine. I can get the Axis Fault as a SOAP fault in my
client.

I've tried to debug the code while using Sandesha2 and it seems to be
a problem in the

run{} method of the "InorderInvoker.java"

The flow of Exception is something like this:
1) I throw a NullPointer exception from generated SKELETON class.

2) Which in turn throws an Axis fault from the Axis2 generated "InOut"class

(HelloWorldServiceMessageReceiverInOut.java).
3) This AxisFault straight away goes into the CATCH block of the run()
method of the "InOrderInvoker.java".
4) There AxisFault is caught and a NEW "SandeshaException" is thrown.
5) This new "SandeshaException" get caught by the external CATCH block
of the same method.
6) And I think the problem lies here ?? Because after catching the
SandeshaException, Nothing is done with it. It is just printed for the
StackTrace.
7) Since the exception is consumed the thread tries to process the
same message again and goes in an indefinite loop.

Please let me know if this is a known issue or I've to do something
else to throw SOAP Fault.

Your help will be greatly appreciated. Because we are at a very
critical path in our project where we will have to take a decision
soon.

Thanks and Regards
Amitesh

correctly.
Let us know.
