Ralph Goers commented on LOG4J2-3046:
-------------------------------------
On the server side you are receiving JSON with the application name in it. As I
said, you have to parse the JSON and then log the result of that. You may have
to create a custom Object to match the JSON so it can be parsed with Jackson.
To be honest, I've never tried that. Once you do that all the data should be
available for you to log, including the application name. I really can't offer
much more help than that.
