James, Thanks for the response. The data is latter. I dont know the structure of incoming message. It can be a simple json or a nested json. I dont have a persistance store. I have a pipeline where a random json comes in and I would like to model the pipeline based on its structure. I need to read this json, present it to the user for further processing. I was wondering if there is something equivalent to jackson library in Java.
