ESB Reprocessing Issue with client API

Question

All,
We are currently working on reprocessing the failed ESB instances using the client API. The instances are getting reprocessed but on a random basis are are getting the below exception. The reprocessing code is also provided.

Answer 1

Hi Rajesh,
I am trying to get the failed instances using the client API in your code what is the FILTER string that you have used since i have used below code to get the payload but not able to get the payload.If you are able to get the payload please do reply me back.
String payload = el.getAttribute("inPayload"); // Not getting the payload
Hoping for early reply from you.
with regards
NK
