Hi All,
My Requirement is create common exception handler kind of accelerator, that should support for all protocols like Mq,FILE,HTTP,SOAP,...etc
1) How can i differentiate the exception is coming from which protocol?
Using InputLocalEnvironment we can to do this, my exact question is it supporting for all protocols
2) Is ther any different set of rules i have to follow to capture for multi protocol excetions
Get exception details, form a some structure which is contain all exception details and send it back to main service or client.
Thanks in Advance
Arunkumar

We do this BUT as you point out it could be difficult to detect the input type.
To solve this we have a subflow (one per type) that the developer puts into the flow BEFORE they do any real work on the message.
This sets the Input message type (and a few other things like to 're-throw' or not) into the Environment. Using the LocalEnvironment relies upon the developer to set the Compute node mode correctly etc. You don't have to do that with the environment.
The common Error Handler will use the message type and extract the relevant data from the ExceptionList.
The development took a bit of time to get right but once done, it saves a lot of time in flow development. It will also be a useful set of code to have in your toolbox.

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