Hi All,
I have a scenario in which i have 2 flows.
1st Flow :- SOAP Input node -> Compute Node -> SOAP Request node -> Compute Node -> SOAP Reply Node.
2nd Flow :- SOAP Input node -> Compute Node -> SOAP Reply Node.
In my flow i m calling 2nd flow from my 1st flow. In my 2nd flow i m getting an exception and i want to pass this exception to 1st flow so that i can handle it with my Error Handling code.
But the problem is that when my flow comes back from 2nd flow to 1st flow my exception list is not populated in the message.
So please tell i am doing anything wrong in this or i need to set any properties for that.
Please suggest

The scope of an ExceptionList is at the maximum the thread that processes one input message. You cannot pass it to another thread. Or you can, with shared memory,if the flows are running on the same execution group. You need to implement it with java. Or with ESQL, but then you will have to put both flows in the same flow file.
You would end up implementing a Singleton with a Hashtable that is using MsgId's as keys, for example. And some housekeeping code for memery management. Not impossible, I have implemented equivalent gadgets myself.
Today, a bit older and perhaps wiser, too, I would start by examining more standard solutions. Like serializing the ExceptionList under the details element of a SOAPFault that you return to the first flow.
Well, that won't be automatically transformed into an exception in the first flow. If you need to do something more in your exception handler, like audit logging, you will have to copy the Fault message into Environment and throw a user exception that would inform your exception handler that there is a Fault message available. For example.
And you need to read the InfoCenter a lot. I read it every day. It's relaxing. |

I always knew you Finns were a strange people. I can't be alone in finding the InfoCentre immensly frustrating especially when you keep going round an round in circles.
I always preferred the PDF's. At least you could search an individual PDF.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

I'm sure this is true, but

Well, if you did read it every day, this might not happen...

I always hated the PDFs, because you could always had to have six of them open to find the full answer to what you needed. And you could only search them one at at time.
And you can create a scope to limit the search in the InfoCenter... Granted, it's only got a limited resolution, but you can still isolate what you want to look into. |

I do also but I passed it off as a British - American writing style difference thing. |
