Hi Thank you for the help!
1.For the json-path library, can you give me some blueprint using example? 2. I have covert the json into a map struction using jackson with the following code <route> <from uri="jms:queue:FEATURES.JSON"/> <unmarshal> <json library="Jackson"/> </unmarshal> <to uri="jms:queue:FEATURES.JSON3"/> </route> How can I get the value of "id" field? Can you give me some example?
